He says to let him go, like it's easy. Good advice, what the doctor did. Letting go. Stop searching, stop fighting, stop hoping.

If it's such good advice, why the hell didn't Dean let him stay dead? Why did Dean make that deal, if letting go is the right thing to do?

Because he's Dean, that's why. And because it was Sam who'd died. Because Dean isn't as important as Sam.

Sam watches Dean walk away and decides, fuck that. Sam's not letting go; not now, not ever.

If Dean can hold on until his fingers fall off or the world burns, Sam won't do any less.
