We'll see how it goes. As much as I'd love to put the bastard outta my misery, I don't wanna cause a scene I can't get away from. But if he were to, y'know, hunt me down or something... I know what I gotta do to get out.

[So there's about as much of a confession as he's willing to give for why he needed all of this.]
