List of Criminal Minds: Beyond Borders characters

Played by Gary Sinise, Unit Chief SSA Jack Garrett is a 20-year veteran agent with the FBI. Jack is the Unit Chief of the International Response Team (IRT), which specializes in solving cases that involve American citizens on international soil. Through his job, he shares personal history with Aaron Hotchner and David Rossi of the FBI's Behavioral Analysis Unit and Clara Seger from his own team. In his personal life, Garrett is married to his wife Karen (Sherry Stringfield) and together they have six children, Ryan, Jack Jr, Josie, R.J., Millie and Emma. His son Ryan recently got into the FBI Academy which concerned him, as Ryan would therefore be putting himself in harm's way as an agent. His daughter Josie recently went away to college. Garrett takes his job seriously and hopes to make the world a safer place for his family to live in.

Alana de la Garza as Clara Seger

Played by Alana de la Garza, SSA Clara Seger is a smart, well-traveled and multi-lingual cultural anthropologist and special agent with the IRT. Before rejoining the IRT in 2016, Seger was married to a man named Brad who was a fellow agent and, like her, knew Jack.[1] In 2013, she took a sabbatical from the FBI after her husband Brad died from unknown causes, which Clara struggled to cope with. She later, reluctantly, returned to the IRT in 2016.[2]

The character did not appear in the series' backdoor pilot (Criminal Minds' "Beyond Borders"), but instead replaced Anna Gunn's "law expert and linguist Lily Lambert"[3] in the first episode (March 16, 2016). When de la Garza spoke to Yahoo! in March 2016, she raved about the ease and comfortableness of the character's wardrobe: flat-heeled shoes, cargo pants, and loose-fitting t-shirts.[4]

Seger is a cultural anthropologist, returning to the Federal Bureau of Investigation's International Response Team[5] in the first season after taking a two-year sabbatical following the death of her co-worker and husband. She speaks 13 languages fluently, including French and Thai, a feat that complicated de la Garza's performances: "That was tricky for me, to kind of swallow it and make it sound authentic. […] In Thai, there was a line I had to say that I kept saying like a question but it was actually a statement. I was like, 'This feels awkward.' It's like retraining your brain."[3]

Played by Daniel Henney, SSA Matthew "Matt" Simmons is a Special Operations agent and special agent with the IRT. Simmons is married to his wife Kristy (Kelly Frye) and has a total of four young children, including sons Jake and David and twin daughters. Like Garrett, Simmons' full and fulfilling family life was a deliberate choice. Through his job, Simmons has some prior history with Derek Morgan and JJ of the FBI's Behavioral Analysis Unit. He was a former member of a Special Ops unit, and his experience with the unit allowed him to hone his profiling skills.

Played by Tyler James Williams, Russ "Monty" Montgomery is a technical analyst with the IRT. Monty has some prior history and friendship with Penelope Garcia, the tech analyst of the FBI's Behavioral Analysis Unit. Much like Garcia, he upholds a positive attitude, though he shows it in a different way. In addition to his job as a technical analyst, he liaises with the families of victims on the American homeland while the rest of his group is away.

Played by Annie Funke, Mae Jarvis is a medical examiner and special agent with the FBI's International Response Team (IRT). Young and spunky, Mae has a fun-loving big bro-little sis relationship with Simmons and was in the FBI purely as a medical examiner before being brought onto the IRT as a resident medical examiner to bypass the bureaucratic red tape in various countries.[1] Jarvis was briefly engaged to a man but later called off the wedding due to her devotion to her job with the IRT.

Played by Sherry Stringfield, Karen Garrett is the wife of Jack Garrett and the mother of their five children.

Played by Brittany Uomoleale, Josie Garrett is the middle daughter of Jack and Karen Garrett's five children.

Played by Kelly Frye, Kristy Simmons is the wife of Matthew Simmons and the mother of their four children.

Played by Ezra Dewey, Jake Simmons is the son of Matthew and Kristy Simmons and David's twin brother.

Played by Declan Whaley, David Simmons is the son of Matthew and Kristy Simmons and Jakes's twin brother.

Played by Matt Cohen, Ryan Garrett is Jack's and Karen's oldest son who is currently training at the FBI Academy and following in his father's footsteps.
