I'm as tired of fighting as anyone. And I don't really know Sam that well, but I know he's a good guy, like...the epitome of a good guy, and I know even if somehow it wouldn't literally, and physically, hurt him to remember everything, he'd damn near kill himself in the grief and the guilt. And he doesn't need that.
I don't really know... Is there some way to reinforce the wall? Plaster the cracks, so to speak?
