Ryan and Debra both try to reassure Claire that they'll find Joey using the video, and Ryan figures that Carroll is playing games with his ex-wife as part of his new story.

The killer then informs Ryan that Maggie's real name is Margaret Schuller and she came to him after she had already killed five people in Arkansas. Carroll warns Ryan that Maggie is a very dangerous opponent.

Ryan slams Mike into the wall and asks if Debra knows, and then tells Mike that Maggie has Jenny. Mike tells him that Debra doesn't know and offers to help.
