A local cop asks Mike if it's true that Carroll has a cult of serial killers -- follower! Keep an eye on this one! -- as he's hanging up pictures of Paul, Jacob, and Emma, and Logical Cop asks Possible Follower Cop, Ava, if Paul might be the guy from the missing-girl case in Rhinebeck. She pulls up the surveillance footage of the convenience store. Mike leans in and transfers the video to the FBI's server, then enhances the image so they can positively identify Paul.
