Dr. Spencer Reid

Played by Matthew Gray Gubler, SSA Dr. Spencer Reid is a genius who graduated from Las Vegas High School at age 12. He is almost always introduced as Dr. Reid, even though the others are introduced as agents, because SSA Jason Gideon understood that people would not otherwise take Spencer seriously because of his young age. After an introduction, he never shakes hands. It has been revealed that he holds Ph.D.s in Mathematics, Chemistry, and Engineering, B.A.s in Psychology and Sociology, and is working on a B.A. in Philosophy. He claims to have an eidetic memory, and hints that he could one day suffer from schizophrenia, since his mother does. ^E408 Matthew Gray Gubler confirmed that Reid has Asperger's Syndrome. In many episodes, Dr. Reid can be seen visiting his mother in her Las Vegas Mental Help/ Nursing Home. In Season 4, "Memoriam", Reid experiences dreams, nightmares if you will, of a young boy being murdered. This was due to a series of events that happened in Reid's childhood. In the end, Reid saw his father after a 20-year absence, and found out that the murders in his dreams were indeed based on a real murder case and that his baseball coach, his mother, and his father were involved in the case, some criminally, like his baseball coach, and some not criminally, like his parents. Matthew Gray Gubler has been known for his many hairstyles throughout the continuing show. In almost every season his hair different, Whether it is a long man bob, or short Albert Einstein hair, if you've seen it, he's rocked it.^[2] Reid has also said that he was bullied when he was younger.

Jennifer Jareau

Played by A.J. Cook, SSA Jennifer "JJ" Jareau originally acted as the team's Communication Liaison with the media and local police agencies. She has a son named Henry (Mekhai Andersen) with detective William LaMontagne, Jr. (Josh Stewart), whom she met while the team was working a case in New Orleans in the season two episode "Jones" and married at the end of the season seven two-part finale, "Hit and Run". In the second episode of season six, JJ was forced to take a promotion to the Pentagon and left the team for the rest of the season. When JJ leaves the BAU for a promotion to a position at the Pentagon, Garcia and Hotch take up her responsibilities as media liaison and retains this position when JJ returns to the BAU as a profiler. Jennifer returned to the show in the episode entitled "Lauren," in which she receives a call and returns to help the BAU find Emily Prentiss and capture Ian Doyle before it is too late. When Emily is stabbed by Doyle and rushed to a hospital, Jennifer announces she did not survive. However, it is later revealed that Emily is alive and Jennifer meets her at a cafe in Paris, where she provides her with three passports and bank accounts to start a new life in hiding. She returns once again in the season six finale before returning as a full-time cast member again in season seven. Jennifer is now a professional profiler. She shows great skills in the field when it comes to her family and protecting other children. In 2015, the actress announced she was expecting her second child, and in the season ten finale, the character announced her pregnancy.

Penelope Garcia

Played by Kirsten Vangsness, Penelope Garcia is the team's Technical Analyst at BAU headquarters in Quantico, Virginia. She is flamboyant and fun-loving and provides the rest of the team with comic relief whenever it is needed. She got her last name from her stepfather—hence the Latina implication—but she is not Hispanic. She was shot and almost killed in season three. She and SSA Morgan share a very friendly-flirty relationship but never go beyond that, although Penelope shows mild jealousy when she sees him dancing with two other women, and he responds negatively when asked for proposal advice by her boyfriend, Kevin Lynch. Penelope lost both of her parents at the age of 18. Penelope taught herself to hack after she dropped out of college and was grouped with the best hackers in the world. After being caught by the FBI, she was given a choice of living in a high-security prison for the rest of her life or working for the BAU division of the FBI as an analyst. She is in a relationship with fellow FBI employee Kevin Lynch. When Jennifer Jareau leaves the BAU for a promotion to a position at the Pentagon, Garcia and Hotch take up her responsibilities as media liaison and retains this position when JJ returns to the BAU as a profiler. After Garcia's parents died when she was 18, she took up hacking as a hobby. In "The Black Queen", Penelope's past is brought up after a series of flashbacks, in those flashbacks the viewers see a Goth looking Garcia. Her story was revealed and it became known that Penelope's skills came from her own teachings to herself. She is now haunted by her past, so much that when her hacker ex-boyfriend needed to be caught, she became bait. In the situation she was really uncomfortable and said that she would never do it again and that she didn't know why she was ever "that" person.

Emily Prentiss

Played by Paget Brewster, SSA Emily Prentiss is the daughter of an ambassador and a U.S. diplomat. After Agent Elle Greenaway left the BAU permanently following a case when she had shot an unsub in cold blood, Prentiss showed up with papers stating she was the newest member of the BAU which caught both Hotch and Gideon off-guard as they hadn't signed off on her transfer. She became a permanent member of the team in "Lessons Learned" where it was revealed that she was fluent in Arabic. She also has a tough relationship with her mother. She got pregnant at the age of 15 and later chose to have an abortion. Prentiss is also skilled at chess. In "The Thirteenth Step" (episode 6.13), Prentiss receives some disturbing news from her previous boss at Interpol. In the following episode, "Sense Memory", after coming home from work, she notices that someone had been in her house because her cat's back was wet and her window was open. She also received several strange phone calls, with the caller ID saying "Caller Unknown". This also leaves Agent Morgan concerned for Prentiss. Prentiss appears in only 18 episodes of season 6. She faked her death to escape an old nemesis with the help of both Hotch and JJ while the rest of the team continued to assume she was dead. In season seven premiere ("It Takes a Village"), Emily returns to the team when Doyle resurfaces and she rejoins by the end of the episode. At the end of the season, she leaves the team to return and run Interpol in London. She returns in the episode "200" (2.14) to help the team as JJ goes missing.

David Rossi

Played by Joe Mantegna, Senior Supervisory Special Agent David Rossi, a "'founding father' of the BAU," was in early retirement from 1997 until his voluntary return to the BAU in 2007, replacing Jason Gideon, who had abruptly resigned from the BAU. He had retired in order to write books and go on lecture tours, but he returned to settle some unfinished business that was not immediately specified. It was later revealed that the case involved three young children whose parents had been murdered in a possible home-invasion case that had remained unsolved. This case haunted Rossi for twenty years and prompted him to return to the BAU, where he eventually solved it.

Dr. Tara Lewis

Played by Aisha Tyler, Lewis is Cahallan's and JJ's temporary replacement while they are both on maternity leave. Dr. Tara Lewis is a psychologist with an eye on forensic psychology and its application toward the criminal justice system. Her dream was to study psychopaths up close and personal – and her psychology background, combined with her experience in the FBI, brought her face-to-face with monsters. Her job was to stare them down and interview them, in order to determine if they were fit to stand trial.

Jason Gideon

Jason Gideon
Criminal Minds character
First appearance	"Extreme Aggressor" 1x01, September 22, 2005
Last appearance	"In Name and Blood" 3x02, October 3, 2007
Created by	Jeff Davis
Portrayed by	Mandy Patinkin Ben Savage (flashbacks)
Information
Nickname(s)	Gideon
Occupation	FBI Special Agent
Title	FBI BAU Senior Supervisory Special Agent FBI BAU Unit Chief
Children	Stephen Gideon (son)

Played by Mandy Patinkin, Senior Supervisory Special Agent Jason Gideon was the BAU's best profiler. He helped Derek Morgan and Spencer Reid through their nightmares. He was shown to have a very close relationship with Reid, having hand-picked him from the FBI Academy for his team, helping Reid through many difficulties (including his implied drug use), and even leaving the good-bye letter for Reid to find. Gideon did not know Garcia well, as expressed through an episode wherein he is placed with her while he is on crutches; after they are placed, Garcia complains about him, and he doesn't know her name. Through the first two seasons, Gideon was portrayed to be very good at chess, winning against Reid many times (only exception being Reid's birthday^E104) and encouraging him to "think outside the box." Prior to the series, he was said to have had a "nervous breakdown" (or "major depressive episode") after he sent six men into a warehouse with a bomb in it; all six agents were killed, and he was heavily criticized about the event. He showed particular dislike for the practice of using religion as a defense or motivation for one's crimes. Gideon participated in some field operations during his time with the BAU and had the rest of his team "think outside the box" as well, as he made a major advancement by shouting at the top of his lungs with pleas of mercy and, when questioned by his team, he said that the victims were being threatened to be kept quiet as neighbors would have heard the pleas if they were unrestrained. He blamed himself for the torture Reid received from Tobias Hankel as he had ordered Penelope Garcia to add a virus warning to the videos Hankel posted.^E215 Gideon also had a son named Stephen.^E111 The nature of their relationship has not been directly stated, but it was implied that they have not seen each other very recently. Gideon began to lose confidence in his profiling skills after Frank Breitkopf murdered his girlfriend, Sarah Jacobs. During his final case in Arizona, he further lost faith in his abilities when his decision to release the unsub resulted in the deaths of both the unsub and a young woman. As a result of his actions, Aaron Hotchner was suspended, which was the final straw for Gideon. He then left his cabin shortly afterwards, leaving his gun and badge behind along with a letter for Reid to find as he sought to regain a belief in happy endings.

In the season ten episode "Nelson's Sparrow", it is revealed that Gideon is dead, having been shot dead at a close range by a serial killer named Donnie Mallick, which prompts the BAU team to investigate Gideon's murder. During the flashbacks focusing on a young version of him for the episode which show him working at the BAU in 1978, he is played by Ben Savage.

Elle Greenaway

Played by Lola Glaudini, SSA Elle Greenaway was formerly assigned to FBI Field Office in Seattle, Washington and was assigned to the BAU, being an expert in sexual offense crimes. Her father was a police officer but was killed in the line of duty. She is half Cuban and speaks Spanish. She was shot by an unsub.^E122 Though she had physically recovered, the event still left her with psychological scars.^E201

As a result of those scars, Elle began acting even more harshly in season two, especially during a case involving a serial rapist.^E205 Ultimately, she killed the suspect before he could even be properly arrested.^E205 During this episode, she mentioned that the unsub wrote on the wall with her blood from the wound.^E205 She handed in her badge and gun in the episode "The Boogeyman" saying that it was not an admission of guilt.

Ashley Seaver

Ashley Seaver
Criminal Minds character
First appearance	"What Happens at Home" 6x10, December 8, 2010
Last appearance	"Supply & Demand" 6x24, May 18, 2011
Created by	Edward Allen Bernero
Portrayed by	Rachel Nichols
Information
Nickname(s)	Seaver
Occupation	FBI Special Agent
Title	FBI BAU Special Agent FBI Domestic Trafficking Task Force Agent
Family	Charles Beauchamp (father) Unnamed mother (née Seaver)

Played by Rachel Nichols, Ashley Seaver is an FBI cadet assigned to the BAU. Her father, Charles Beauchamp, was a horrific serial killer from North Dakota known as "the Redmond Ripper" who killed 25 women over the course of 10 years before Ashley was a teenager. He was caught by David Rossi and Aaron Hotchner. Because North Dakota does not have capital punishment, he was sentenced to life in prison. She has not been to see him. Though he writes to her sometimes, she never reads his letters, though she does keep them and admittedly still finds herself unable to hate him for what he did. In the episode "What Happens at Home", the BAU investigate a series of murders in a gated community and bring Ashley along because of her understanding of the family dynamics of a serial killer. In the end, the suspect commits suicide by cop in front of her. In the next episode, she requests that the rest of her remedial training be done with the BAU and is attached to the team. In the season seven premiere "It Takes a Village", it was revealed that Ashley transferred to the Domestic Trafficking Task Force, which is led by Andi Swann.

Dr. Alex Blake

Played by Jeanne Tripplehorn, FBI Linguistics expert Dr. Alex Blake replaces SSA Emily Prentiss. She is introduced in season eight. Her appointment at the BAU was met with some mixed reactions as the team was close to Prentiss. She retired in 2001 until she rejoined the BAU in 2012 to restore her reputation after Blake was blamed for arresting the wrong suspect in the Amerithrax case and Section Chief Erin Strauss let her take the fall. As a result, she and Strauss do not get along, with Strauss accusing her of joining for selfish reasons, but they eventually make amends. The rest of the team recognize her expertise and are generally less antagonistic towards her. As season eight progressed, Blake found herself in danger when she was threatened by a serial killer, 'The Replicator', who turned out to be John Curtis: a fellow former FBI agent disgraced due to the events of the Amerithrax case, who targeted Blake out of envy that she had restored her reputation while his own was still in ruins. Curtis killed Strauss, kidnapped Blake, and tried to blow up the entire BAU team, but the team rescued her, and Rossi locked Curtis in the house to die when the bomb exploded as vengeance for Strauss's death.

Blake graduated from Berkeley with a double major and also holds a PhD. She was recruited to the FBI at the age of 24, making her one of at least two team members to join the Bureau in their early 20s along with Spencer Reid. Blake is also a professor of forensic linguistics at Georgetown, where Reid had previously guest lectured, and an SSA in the Washington field office. During her initial time at the FBI, Blake was involved in some high-profile cases, particularly the Unabomber case.^[3] Blake understands and speaks American Sign Language.^[4]

In the season nine episode "Bully", it is revealed that Blake is estranged from her father Damon (a retired police captain of the Kansas City Police Department) and younger brother Scott (a current homicide detective there himself); after the death of her older brother Danny (a cop killed in the line of duty) and her mother, she found it too painful to be near her father and brother, and distanced herself from them. However, after Scott is injured by the UnSub, the two siblings start to reconnect, and by the end of the episode, she reconciles with both Scott and Damon when she and the rest of the BAU team have a barbecue at her father's home.

In the season nine two-part finale, Blake becomes distraught and depressed when Reid is shot in the neck by the UnSub after pushing Blake out of the way and nearly dies, even commenting that it should have been her who was shot instead. She is also further upset when rescuing a young boy who was being used by the UnSub as leverage against his mother. Though Reid survives, Alex is greatly shaken by the case, and reveals to Reid that both he and the young boy reminded her of her deceased son Ethan, who died of an unnamed neurological disease at age nine. Her guilt and distress over Reid's brush with death touched a major nerve with her, seemingly pushing her to the breaking point. At the end of the "Demons", she sits apart from the rest of the group on the plane ride home, and it is implied that she sends a text message to Hotch handing in her resignation. After taking Reid home, telling him about Ethan, and departing, Reid finds her FBI badge in his bag, and watches her leave, saddened but accepting, from his window.

Kate Callahan

Occupation	FBI Special Agent
Title	FBI BAU Supervisory Special FBI Undercover Agent
Family	Unnamed mother Liz (sister, deceased) Joe (brother-in-law, deceased)
Spouse(s)	Chris Callahan
Children	Meg Callahan (niece/adopted daughter) Unnamed child

Played by Jennifer Love Hewitt, Kate Callahan has been in the FBI for eight years and has experience as an undercover agent, which has allowed her to establish a prior friendship with members of the BAU. Her sister and brother-in-law were killed in the September 11 attacks, leaving Kate as the legal guardian of their infant daughter, Meg, whom she raised for thirteen years along with her husband, Chris. This tragedy shaped her patriotic attitude. She is described as "smart, charming, and wise for her years" and holds a passion for making the world safer, according to showrunner Erica Messer. In the episode "Breath Play", Kate reveals she is pregnant. In the season ten finale, "The Hunt", Meg is abducted by human traffickers who are connected to a previous case that Kate had researched. Though Meg is eventually brought back safe, Kate decides to take a year off to spend with Meg, Chris, and her soon-to-be-born child.

Derek Morgan

Played by Shemar Moore, SSA Derek Morgan is a confident and assertive everyman character, the son of an African-American father and white mother. He went to Northwestern University on a football scholarship, holds a black belt in judo, runs FBI self-defense classes, and served in a bomb squad unit and as a Chicago police officer. In season two it was explained that after the death of his father when he was ten, Derek struggled somewhat: youthful fighting earned him a juvenile offender record. He was taken under the wing of a local youth center coordinator, Carl Buford (Julius Tennon), who acted as a surrogate father to Derek and helped him to obtain a college football scholarship. But he also sexually abused him; the episode "Profiler, Profiled" revealed this. In season three, it was revealed that he hated religion because, as he said, something bad happened to him when he was 13. He went to church every day and prayed for it to stop, but it did not. Because of this, he had a resentment towards God and church. He prayed for the first time in 20 years at exactly the time, he later found out, that Penelope Garcia was being operated on after being shot. Former Unit Chief Aaron Hotchner promoted him to unit chief in his place, a promotion Derek saw as only temporary until the "Boston Reaper" was captured. Aaron again took his place as unit chief when he returned after grieving over his ex-wife's murder. He resigned to care for his family.

Aaron Hotchner

Played by Thomas Gibson, Unit Chief SSA Aaron "Hotch" Hotchner used to be a prosecutor and was formerly assigned to the FBI field office in Seattle. After stepping down for a period, he returned to lead the unit. He has a son named Jack (Cade Owens) by his deceased wife Haley (Meredith Monroe). The two eventually divorced and remained on good terms until Haley was murdered by George Foyet (C. Thomas Howell), Aaron's Nemesis. Aaron's attempts to balance his family life and his job have been something of an ongoing struggle on the show. When Jennifer Jareau leaves the BAU for a promotion to a position at the Pentagon, Garcia and Hotch take up her responsibilities as media liaison and retains this position when JJ returns to the BAU as a profiler. But in the episodes "Closing Time", "A Family Affair," and "Run," it is shown that he has moved on and is currently in a romantic relationship with Beth Clemmons (Bellamy Young). It is known that "Hotch" is rarely seen smiling throughout the show. His most notable smiles are when he is with his now girlfriend, played by Beth Clemmons and his son, Jack, played by Cade Owens. Gibson will appear in 1-2 episodes in the forthcoming season; he will then immediately be removed as a cast member.

Current

Agent Grant Anderson

Played by Brian Appel, Agent Anderson appears in "Plain Sight" (episode 1.4),"The Fisher King" (1.22 and 2.1), "The Big Game" (2.14), as well as "Honor Among Thieves" (2.20), "The Crossing" (3.18), "100" (5.9), "The Slave of Duty" (5.10), "Hope" (7.8), "Hit" (7.23), "Run" (7.24), "Carbon Copy" (8.16), "The Replicator" (8.24), "To Bear Witness" (9.4), and "200" (9.14). Agent Anderson was told to drive Elle home in "The Fisher King", and he dropped her off at her front door and left. She was soon shot by The Fisher King, as he had already been there, waiting for her. Hotch scolds Anderson briefly for not doing more, and quickly sends him back to the scene of the crime.

Agent Josh Cramer

Played by Gonzalo Menendez, Agent Josh Cramer runs the FBI Field Office in Baltimore, Maryland, as well as the Organized Crime division in that city. The two episodes which take place in Baltimore, "Natural Born Killer" (1.8) and "Honor Among Thieves" (2.20) both have him liaising with the BAU.

Diana Reid

As played by Jane Lynch, Diana Reid is Dr. Spencer Reid's mother. She first appeared as a potential target of serial killer Randall Garner, the man who shot SSA Elle Greenaway.^E122 Like her son, Diana has a genius level IQ. She was once a university literature professor, but is no longer since her diagnosis of schizophrenia. She currently resides at the Las Vegas-based Bennington Sanitarium, where Spencer committed her when he was eighteen. Her husband, William Reid, left her when Spencer was a child. The reason William left is because he was aware Diana witnessed a murder, as a family friend avenged his own son's murder. He was unable to live with this knowledge though he claims he tried; he said "the weight of knowing what happened was just too much." Much of Diana and Spencer's time while he was growing up was spent with her reading to him. Spencer writes her a letter every single day because he feels guilty about not visiting her. In season 11, Spencer takes some time off from the BAU to visit her. In "Entropy", he reveals she has early signs of Dementia and when he first walked in her room, she didn't know who he was for three seconds.

Kevin Lynch

Played by Nicholas Brendon, Kevin was Penelope Garcia's replacement when she was briefly suspended and hospitalized.^E309 He is a former hacker like her, but he is far messier. Garcia is denied access to her system during her suspension from the BAU. Kevin takes over in the interim. He is immediately impressed with the system she has set up and her GUI. Garcia attempts to hack into the database under his watch. Kevin is unable to block her. They are each impressed with the others work, but Garcia establishes dominance. When they finally meet face-to-face, they fall in love instantly. Kevin remains in awe of Garcia. They've developed a dating relationship in spite of Garcia's 'special' relationship/mutual admiration with Agent Morgan. This is revealed at the beginning of Damaged, when Agent Rossi shows up at Garcia's apartment only to find the quirky twosome showering together.^E314 In the season six finale "Supply & Demand", they profess their love for each other. Later in the show Penelope brings him in for a case in season 6.

William LaMontagne Jr.

Played by Josh Stewart, LaMontagne is the husband of Special Agent Jennifer Jareau. He is a homicide detective who worked for the New Orleans Police Department and is now with the Metro PD. In the season two episode "Jones", it is revealed that his father William Sr. was a detective himself in the NOPD and was killed during Hurricane Katrina as he was working a case in his home and refused to leave during the mass evacuations. The case later resurfaced and LaMontagne enlisted the help of the BAU.^E218 While they were there, he and JJ became romantically involved, although he wasn't mentioned again until "In Heat". In that episode, he was brought to Miami where the unsub had killed a friend and colleague of his. During the episode, it was revealed that he and JJ had been secretly contacting each other since "Jones". JJ didn't want to reveal their relationship since she believed it would complicate their personal lives, but in the end, they went public with it. At the end of the episode, it is revealed that Prentiss, Morgan and Reid already knew about it. In the episode "The Crossing", JJ discovered she was pregnant and they have a boy named Henry. The actual status of JJ and Will's relationship (engaged, married, etc.) has not been disclosed, though they exchanged rings with Henry's birthstone in season four. In the season three finale, it is revealed that he transferred to Metro to move to Virginia to be with JJ and raise Henry together. To conclude season seven, he and JJ marry in a small ceremony in David Rossi's back yard.

The character was written back in after A.J. Cook told the writers she was pregnant, and as such JJ needed a love interest. In addition, one of the original plans for the season seven finale was to kill off Will. However, this idea was scrapped due to Paget's impending departure.

Jack Hotchner

Played by Cade Owens, Jack Hotchner is the son of series regular Aaron Hotchner, his first appearance being in "The Fox". His mother, Haley Hotchner, is killed in season five by George Foyet (a.k.a. "The Boston Reaper") but is spared when his father gives him a secret signal to "work the case" (hide in the trunk in Hotch's office). It is shown in season seven's "Painless" that Jack is being bullied. Jack is shown to have become good friends with Beth Clemmons, his father's new girlfriend.

Henry LaMontagne

Played by Mekhai Andersen (A.J. Cook's son), Henry LaMontagne is the first son of Jennifer Jareau and William LaMontagne Jr., his first appearance being in "100".

Mateo Cruz

Played by Esai Morales, Cruz is the new Section Chief of the BAU. All that is known about him is that he worked at the Pentagon prior to season nine and has a past with JJ.

It was revealed in "200" that the two had worked on a task force together in the Middle East. He was the only person to know of her pregnancy and her miscarriage during her time on the task force. In the same episode, they are both kidnapped by Tavin Askari, who was a traitor within the task force. They are both physically and mentally tortured into giving the access codes given to them during the mission. He is shocked to discover that Michael Hastings, one of the men they had worked with on the task force, was the mastermind behind the plan and threatened to rape JJ in order to give him the access codes. He gives in and is later stabbed by Askari, who was quickly killed by Hotch. Cruz is taken to the hospital following the incident and survives. Cruz later appears in the season nine finale "Demons", where he accepts a case from the sheriff who is a personal friend. When the sheriff is killed and Reid is shot, both Cruz and Garcia fly to Texas to meet with the rest of the team. He is next seen in the pilot episode for the upcoming spinoff, entitled Criminal Minds: Beyond Borders, which was the nineteenth episode of season ten. He enlists the BAU to help the international team find a vicious international killer in Barbados.

Joy Struthers

Played by Amber Stevens, Joy is Rossi's daughter from his short-lived second marriage to French diplomat Hayden Montgomery. When they divorced, Hayden didn't tell him she was pregnant and Joy thought her father was her mother's second husband, who finally told her the truth before dying from cancer. In the episode "Fate" (10x09), Joy sought Rossi out and they're getting to know each other. Joy is a reporter and true crime writer and is married with a 2-year-old son named Kai.

Former

Erin Strauss

Played by Jayne Atkinson, Erin Strauss was the BAU Section Chief, the direct superior to SSA Aaron Hotchner. Her job lies in administration, and she has little field experience. Strauss becomes more prominent in season eight. It is revealed in "The Silencer" that the newest member of the BAU team, Alex Blake, worked with her during the Amerithrax case, during which Strauss left her to take the fall when a linguistics flub led to the arrest of the wrong suspect. As a result, Blake did not get along with her afterwards. At the end of "The Silencer", Strauss tries apologizing to her, but Blake turns Strauss down. In "Carbon Copy", she specifically oversees the investigation into the Replicator, and by the end of the episode, she apologizes to Blake again, and this time, her apology is accepted. In "Brothers Hotchner", she is abducted by the Replicator, later revealed to be a former FBI agent named John Curtis, whom she left to take the blame along with Blake following the Amerithrax case. In "The Replicator", Curtis poisons her with spiked wine and leaves her to die. She is found on the streets by Hotch, and she admits that the Replicator forced her at gunpoint to drink again. She dies in Hotch's arms after begging him to stay with her as she does not want to die alone. Strauss indirectly helps defeat Curtis post mortem when Rossi uses her sobriety chip to escape his trap, leaving him to possibly die in an explosion. After her funeral, the team celebrates her life during dinner at Rossi's garden, discussing happy stories of her time with them and acknowledging her as a good woman, friend, and mother.

Haley Hotchner
