The librarian/doctor ignores this and injects the shopkeep, in his arm. Then he withdraws the needle, and nods: "Go ahead. Try 'em out." The shopkeep seems surprised that that was all it took, but he lurches to his feet with the help of one of his crutches, which he then casts away before taking a few halting steps. "Thank you," he says to the librarian/doctor, who is all, "Thank you," because he has the box with the doomsday-machine component that Fauxlivia handed over to him earlier.

And over in Boston General, a groggy Olivia wakes up, and is somehow not startled to see Peter all stubbly staring at her. She says his name, and he takes her hand and says he's sorry. She shakes her head and tells him not to apologize: "You were the only thing that got me through. If it wasn't for you, I would never have made it back. You saved my life." He leans in and kisses her on the forehead as she closes her eyes, and then he hovers over her face. We're going to leave them there, where I assume he delicately broaches the subject of just how advanced things got with Fauxlivia and how he doesn't think it's necessarily fair that he should have to start back at first base.
