Where are the actors from Criminal Minds now?

The Team Leader role was played by Gibson for 12 consecutive years until a disagreement over "creative differences" occurred with the writers.

Only one appearance by Gibson on the big screen has been noted since 2017, in Axis (2017), and another on the small screen in Shadow Wolves (2019).

It suggests that something must have gone awry.
