He walks as if in a daze across the main dispatch room and into a stunningly lovely library. If he had looked at Amelia with a tenth of the love he's showing here, their romance might have approached believability. Dean is impressed as well. "Sammy, I think we found the Batcave."

In no time at all, they've each settled in, in their own ways. Sam immediately gets his nose in a book while Dean avails himself of a shower. Sadly, we only see the aftermath the latter, which is that Dean pads around in slippers and flannel robe, extolling the virtues of indoor plumbing. Sam and I both wonder how they even have running water or electricity, but Dean's too happily clean to care. Dean peers at the books Sam has laid out on a table. "Listen, little brother, let's not go all 'geek' on this stuff," he says. An instant later, he's geeking out over a scimitar he finds atop one of the bookcases. Still, he tries to keep his enthusiasm in check, saying it's not like the Men of Letters knew anything they don't know. Sam points out that they were a secret society. They knew all the secrets, except the secret to survival. I, for one, would like to know why all of Sam's shirts lately have diamond-shaped buttons. It's up to Sam to argue the virtues of a place like this, because the show wants to make it absolutely clear as to who's going to be the Man of Letters and who is to stay the hunter. Dean looks thoughtful, but says nothing. Sam scoffs and glances down at Dean's new outfit. "You gonna take off the dead guy robe?" A thousand "Wincest" fans get the wrong idea and faint dead away.

Meanwhile, in Wilkes-Barre, Pennsylvania, a white-haired Barney Miller hobbles into a library. He's greeted by a snitty librarian. "Well, well. So late. I didn't expect you in at all," he says. "Three times I had to transfer the bus lines to lose him today," says Barney Miller. The librarian doesn't believe him, nor does he really care. Barney Miller asks for a particular manuscript and has apparently been working his way through the whole section for some time now.
