Mike fills us in: six murders from 2002 to 2005, all the victims stabbed. Another agent shows them the police sketch and says when she visited Carroll she used an alias.
Emma asks Paul for the phone and asks if he saw the news. He did: there's an all-points bulletin for Maggie. Emma calls her and leaves a message, telling her to call them. She's worried. Joey is watching from the top of the stairs. When Emma calls him, he picks up his boots, runs down the stairs and goes outside with his soccer ball. Emma asks Paul what's going on in the basement. He says Jacob is supposed to be taking care if it--if he can take care of it, he emphasizes. Emma asks what that means, and Paul says he knows Jacob better than she does, after their three years of pretending to be a couple.
Emma and Paul squabble over Jacob some more, with her telling him she doesn't care if they fooled around and Paul's in love with Jacob, but it's over now, and Paul protesting that it's not about that. He insists that Jacob is lying to everyone. Jacob has never killed anyone, Paul says, as if that's a bad thing. He's delighted with Emma's surprise.
Mike shows security camera footage of a hardware store parking lot: it's Maggie, stabbing some guy to death to take his car. She bought rope, tape, a flashlight and magnets. They all wonder about the magnets while Ryan points out that the hardware store was close to I-95, which would be the way to get to New York or Connecticut, which is where forensics thinks the tape was made, based on the trees and grass.
Ryan's phone rings again; it's Jenny. Flashback. The same woman is watching Ryan sleep. He wakes up from his alcoholic stupor and she says he missed his last few doctor's appointments, which isn't a good idea for someone with a pacemaker. He tells her she doesn't need to take care of him, but Jenny says she cares about him. She tries to convince him to get some help for all his fucked-up-ness, but he snaps at her and she leaves.
Ryan answers the phone. He asks if everything's okay, and Jenny says it's not. Then Maggie comes on the line. He asks her what she's doing with Jenny. Maggie says she won't keep him, since she knows he's busy, but asks how he wants her to kill his sister. Painlessly and in fifty years?
