Unsub!Elle frames Reid

I don’t remember too much about this story. I know men were being killed and it looks to the team like it could be Reid. I think he was at the places were the men were either last seen or killed. I think Elle mention she thinks it could be Reid.

Morgan and Reid are together and Morgan feels bad for thinking it could be Reid. Turns out that the killer is Elle because she is jealous of Morgan and Reid.
