Anti-Sam. There was a little ghost of a smile at the name. Sam appreciated that Fred had separated him in her mind like that, even though he didn't feel all that worthy of second chances. If she knew... all the decisions he'd made that led to that point. If she knew, maybe she'd feel differently.
As it was, he didn't much feel up to going into explanations of those things just now so he settled for rolling with the change of subject.
He considered for a moment, how much to tell her. If the Men of Letters was in fact a secret society, betraying their secrets to just anyone might not be wise. Then again, Fred wasn't just anyone and Dean had already mentioned wanting to tell her. Dean seemed to think that she could help with exploring the place and perhaps she could.
Sam picked up the notebook containing all of his notes on what he'd learned so far. He didn't expect her to read the whole thing, but he slid it over to her.
"I'm looking into a society called the Men of Letters. Trying to figure out if it's something native to the City or if it's from our world."
