This led to a hostile relationship between Blake and Erin Strauss, the BAU section chief.

However, they eventually make amends and maintain a solid working relationship.

Blake worked as a linguistics expert and was revered for her intelligence.

Similarly to Greenaway, it was also psychological trauma that led to Blake leaving the BAU.

She was last seen in the Season Nine finale, “Demons”.

After Spencer Reid was shot whilst saving Blake’s life, she became overwhelmed with guilt and depression.

Blake left her FBI badge in Reid’s bag and went on to pursue a career as a teacher.

Simmons was first introduced in the spin-off seriesBeyond Bordersbut has been a member of the BAU since season 13.

Though since Henney is currently also starring in Prime Video’sThe Wheel of Time, a permanent return seems unlikely.

His relationship with Reid was brotherly, and the two shared a strong bond created through their mutual experiences.

Perhaps an even more prominent relationship for Morgan was his loving friendship with Garcia.

Garcia is a technical analyst for the FBI and is often considered the best in the business.
