Ah. So Sam is alive. That's—something. He watches you reconsider and sink down onto the bed again. You're concerned about him working with Sam.

"Why wouldn't I be." It's a flat question, a non-question. He hasn't thought about Sam Winchester much at all in years, besides wondering how much of Sam remained aware behind Lucifer's Grace. If Sam ever regretted saying yes. He must have, if he retained any moments of consciousness.

Your question makes something clear, however: Sam will always have your loyalty before he does. For you to allow him to stay, he needs to get along with Sam. He's never very good at getting along with people when it doesn't involve sex. But he'll try.

For now, though, since it won't be just them together again—he'd still like you to stay the night. "I don't have—a bag." To put his things in. He has two other shirts, besides what he's wearing, but he'd like to bring to the comforter and his books. "Tomorrow morning when Target opens, we could buy one."

We. It forces them to spend the night here. He'd like to spend the night here with you. In a house full of photos and books.
