BY THE BOOK
WOW: stiff. vaguely spoilery for Season 9. Newly-human Castiel takes Dean's advice. The brothers sort of wish he hadn't.
Disclaimer: I don't own them, and they should be very grateful for this.

The brothers peered round the doorframe into the Bunker's cavernous library where Castiel sat in rapt concentration, turning the stiff vellum pages of one of the library's antique books.
"Dean," Sam sighed; "remember you told Castiel that he could learn about human interaction by reading books?"
"Don't remind me," snorted Dean; "he's been wishing me happy unbirthday every day after reading Alice through the Looking-Glass."
"And then he was all angsty and maudlin after reading Hamlet," added Sam.
Dean nodded in agreement.
"Well, I don't want to worry you or anything," Sam whispered; "but he's reading Lady Chatterley's Lover now."
