Jason Gideon
First: Anyone recognize these faces?
Gideon’s character arc is painful.
Hotch’s first introduction is a testament to who he is.
Derek Morgan
First: 1940s, he put bombs in train stations and movie theatres.
Last: You’re welcome.
Derek Morgan is introduced in possibly the most Derek Morgan way.
There’s charisma and class to his character, straight away.
Viewers see his character go through unimaginable pain and loss and reckoning.
Jennifer “JJ” Jareau
First: Good.
Because these go to you.
Last: And here I thought I was out of tears.
Jennifer, or “JJ” to her friends, starts off as the unit liaison for the BAU.
She climbs her way up the ranks from unit liaison to profiler and key member of the group.
In her first scene, she impresses the team with her knowledge of each member and their esteemed career.
Her emotions have often allowed her to empathize with victims in a way like no other agent.
Emily Prentiss
First: Hi, Agent Hotchner?
Last: This will be her maiden voyage.
Emily is a later addition to the team, but she’s an invaluable one.
She’s introduced in Season Two as a new team member after Elle Greenaway resigns from the FBI.
David Rossi
First: Go on, boy!
Last: I love the smell of a new jet in the morning.
Senior Agent David Rossi is introduced shortly after the departure of Jason Gideon.
Eventually, it becomes apparent that he cares for the team deeply, despite his reservations.
Luke Alvez
First: I’m from the Bronx, lady.
Last: Moving out of here like the Colts did Baltimore?
Luke Alvez had big shoes to fill, coming in as a replacement for Derek Morgan after his departure.
His first scene sees him undercover as a fugitive agent, capturing convicts on the run.
Much of Luke’s character is based on his time in the Army and in the Fugitive Task Force.
While he served as a replacement for Derek, Luke carves out his own path as a unique character.
He’s definitely the muscle for the team, but he’s also so much more than that.
Matt Simmons
First: Three families, three countries, in three years.
Last: We got a new one?
Matt is introduced as a member of the International Response Team in season ten.
He’s stoic and one of the pillars that keep the team together.
Tara Lewis
First: Absolutely.
Last: So, you expecting the Queen?
As one of the late starters, Dr. Tara Lewis has some catching up to do.
Spencer Reid
First: They’re calling him the Seattle Strangler.
Last: I’m gonna name her Mildred.
Similar to Gideon, viewers first meet Spencer Reid at Quantico.
He’s introduced as the shy, soft-spoken, young genius of the team.
He’s one of only two characters who were in the first and last episodes of the show.
His last line is simple and perfectly encapsulates the eccentric nature of his character.
