But you also come back. You may die but you still come back.
From the looks of things, only something major, massive death of more than one person would attract his attention.

Sit in a hospital waiting room, just to see. Sam and I are going to be there. And if he dies by supernatural causes, he has a ring that will bring him back. If something happens and there's a risk of him dying normally... I can kill him and he'll come back.
I don't like it, but Sam seems to think it's the best option right now. I know Jeremy, which was why I had asked before how dangerous it would be, because he'd offer if it meant there was a chance. This way at least I know he's not alone.
