Will finds matches and lights a lantern, then looks at Gwen's stab wound. He puts alcohol on it from a whiskey bottle he finds among the gardener's things, then improvises a bandage for her leg. She asks where he learned to do that, and he says his dad taught him. Gwen says, "Don't you wish you could call your dad right now?" and he agrees, but he tells her Hal is in Washington working on a case. When she asks when he'll be back, he says he's not sure, but he thinks his dad would approve of the bandage he's just made. Gwen thanks him, telling him that's twice he's saved her life, and she apologizes for the first time, when Casey and the police basically accused him of having attacked Gwen himself. She says she knew then that he couldn't be capable of something like that, yet she stood by silently, even though she'd promised him to always be there for him. She asks if he can forgive her, and he says of course, because he still loves her so much, and he just wishes everything could be different. He leans in to try to kiss her.

Elsewhere at the lake, Maddie bangs on the door to the bus, begging the other teens to let her on, but they drive away.

He tells her she won't get away with killing his friends; Maddie insists she didn't kill anyone, but Ian attacks her with a boat paddle anyway. Maddie hides in the boat house, and Ian keeps looking for her. Maddie gets out of the boathouse, but after stumbling around in the dark some more, she comes across Ian, now stabbed to death like the others.

Maddie apologizes to Casey, telling him it's her fault he's dead; Louis comes up and grabs Maddie, who knees him and runs again.

Maddie screams.
