Seeing Sam.. it's like getting stabbed all over again. His chest is tight and he can't quite breathe as much as he'd like to. Needs to now, considering he's human.

"Probably not. Let me guess, someone tried to hit you with a car or something and it bounced off you like a superball. And you, being you, went and hit the books."

The spell was supposed to be unbreakable and more importantly, untrackable. Sam was supposed to live out his life safe and never really knowing that Gabriel had not only died for him, but he'd offered up his grace to keep him protected.

Fucking loopholes.
