Specimens in its use strikes Sam's interest and he notes for himself to look into that later, perhaps specifically to see a little more of what that might entail. What sort of specimen are being collected and for what use? He could ask Ciri, he figures — have the answer immediately — but opts instead to take on her question.

He couldn't abandon Dean, couldn't make that decision again even if urged to do so. (That's the feeling this week, at least.) And so he shrugs. It's nice to feel the guise of options for once, even if he's not saying as much.
