Mike is looking at the computer Carroll used, which he's infected with a virus so Mike can't figure out the sites he visited. Ryan asks who the guards were who were supposed to be supervising Carroll's Internet use and Riley says there was one constant, Jordan Raines. He's Candice Bergen's bum of a son from Miss Congeniality! And he helped Carroll escape.
The troops head to Raines's house. Turner bangs on the door and when there's no answer, they break the door in. The house is empty. Ryan finds a wall full of missing-dog flyers, and when Mike wakes up Raines's computer, there's a video of Raines with a puppy -- I don't think I can do this, you guys. Carry on without me until the threats of violence toward puppies are over. (I know. Animal violence bothers me more than people violence. I blame James Dobson.)
Turner shows everyone Raines's abattoir, which is full of bloody saws and chains and a German shepherd that is maimed, but STILL ALIVE OH MY GOD. Mike observes that Raines was "practicing" and Ryan replies that Carroll was teaching him how to be a serial killer. So maybe he shouldn't have been a prison guard, hmm? Do we not have behavioral evaluations for this kind of shit? Aaaaaah.
Mike is also bothered by dead dogs more than dead people. I knew I liked you, Iceman. I forgive you for being a dick to Veronica Mars (wait, that wasn't you). Ryan has found a copy of Carroll's novel, which he signed for Raines. Mike observes that Raines is lonely and unstable, so he looks up to Carroll the way Carroll looked up to Poe. Mike fanboys out a little about Ryan's work on the Carroll case the first time around. Mason interrupts all the bro love to tell Ryan it's time to go talk to Claire.
Sarah and her boys are watching TV, still, and I'm sorry, gay boyfriends, but if your friend was the last victim of a notorious serial killer who's now escaped and maybe is on his way to her house to scoop out her eyeballs, you do not watch the fucking news. This is a time for RuPaul's Drag Race. Or Road Runner cartoons. Something thoroughly not murdery. One of the boys agrees with me and says they should watch a movie, but Sarah says she wants to go lie down. They say they're right next door NO, NO, DO NOT LEAVE HER. Sarah goes to her room and takes her shirt off. She looks at her scar in the mirror. Correction: scars. Eek.
