Which, thankfully, IS something that Sam's been thinking about. "The Men of Letters left one hell of a library here. I've been working on figuring out what's in there and getting it organized, so it would be great if you could help me out with that. And Kevin, for all that he's good at it, actually really hates doing research." Or, more specifically, research that he didn't see much use in. Which was a lot of what Sam and Dean did. "Don't get me wrong, Kevin's great in a lot of other capacities, but he's not great at being left in the library."
