Dan hates libraries. That isn't surprising, given that he can't read and that Sam's gentle and insistent coaching is the only reason he can even sort through his initials. It's one thing to exist in a culture that's hostile to a part of him; it's another to walk into the halls of a world totally beyond him, with secrets everyone else can access except for him, and that sense of inadequacy makes him grumpy, at least, as grumpy as Dan ever gets over things that aren't personal but certainly feel personal.

"If it ain't Sam Winchester. Fancy seeing you here." Dan's voice is already a quiet croak, so he barely has to lower it to be properly relevant to the library's purpose, but he does sit on the edge of the table rather than a chair, the only indication that he isn't properly genuflecting to the concept of literacy. "I got no idea how long you been here. I just got back from New Zealand."

Bunny's been taking Dan around on tiny missions, anywhere they can go together to do what they love best, which is saving the day. He's only dropped Dan back off because the next call to action was something that would probably require a few days without sleep, and Dan's already running on fumes, despite feeling energized by the adventuring.

"How are you?"
