Shemar Moore reprises his role as Agent Derek Morgan on this season's finale of Criminal Minds (airing May 10).
Per CBS, "Derek Morgan comes to the team with a lead that might help find Mr. Scratch, the elusive fugitive that has been taunting the team all season."
Here's a preview on what to expect, per EP Erica Messer:
It's tied to what happened to him last year a little bit.
Scratch isn't getting to Hotch (Thomas Gibson) to get us that message because Hotch is in Witness Protection, but he did get to Morgan even though Morgan is a civilian now. That's still a little disheartening that Scratch can have so much reach.
Messer also teased that the final hour will wrap with a cliffhanger:
It isn't a car exploding [like in Season 3], but it is a legit cliffhanger that we haven't done in a really long time, so that's kind of exciting.
We get to start Season 13 in a different way. You'll be asking the same type of question: 'Who was that?' 'Are they OK?'
