Rachel Nichols (Ashley Seaver)
We only saw Rachael Nichols in the role of Ashley Seaver for just one year. The character was an FBI cadet born to a serial killer dad. She was transferred to a task force that dealt with domestic trafficking towards the end of the sixth season. The actress went on to play Angela Roth in Titans. Aside from that, she also became a part of the cast of The Man in the High Castle in 2019.

Jennifer Love Hewitt (Kate Callahan)
There is no doubt that Jennifer Love Hewitt was one of the most famous figures to join the world of Criminal Minds. She was only in one season of the show in the role of Kate Callahan. It was a short stint, but it was eventful. Her character was heavily pregnant when she nearly got human trafficked! The actress went quiet after this gig, but she did make a comeback in 9-1-1.
