Right now the only way I can see Sam bieng a vessel is if Sam thinks he can trick Lucifer and somehow defeat him but he doesn't manage to pull it off.

do you think there's any chance that Sam would in fact end up saying yes?

When Lucifer definitively told Sam that Sam would say yes, didn't he tell Sam it would be in 6 months, and that it would take place in Detroit? (I'm upstairs right now, and the DVR is downstairs. I'm hoping one of you people with the photographic memories retained the info.) Because it seems to me at the time it worked out that if Lucifer wasn't lying his ass off, that the 6 months timeframe worked out to some time in May. I figured it would make a hell (no pun intended) of a season finale.

We've heard Detroit referenced twice. Lucifer said that's where it would be, and in Dean's trip to the future. I assume we'll be visiting Detroit soon. What I don't remember was whether Sam went there alone in the now-defunct future, if it was addressed at all (I think it was, and I think he did, but it's been months since I've seen it).

Morgana, I also remember the "hey, that's May!" time prediction.

The only way I won't (I think) be completely upset with Sam saying yes is if it's a plan. If he caves, I'll probably be pretty bitter.

There might be ramifications (as in, no takebacks) from Dean already having said yet, and that seems fair. Unfortunate, but fair.

A plan could play out in really cool ways. I just think someone's got to say yes to someone and make it stick, or the whole setup will seem anticlimactic.

Either way, we're in for pain.

I honestly don't think there would be a S6 if Sam said yes deliberately and without it being part of a plan. After winning back Dean's trust, which is what S5 has been all about, throwing it away would destroy their relationship utterly, beyond redemption.

If he's tricked into it somehow, or if he agrees as part of some plan, that's another thing.

I don't particularly want another season of rebuilding trust. I'll watch this show regardless of where they land, but I hope S6 has something new to tell.

I think there will be Dean!Michael and Sam!Lucifer in the finale. I like the tricked into it or part of a plan scenario best.

I would really like Sam to have grown solidly beyond the point of being tricked into it. I guess if it's really clear to Dean he was suckered in, but still I think it would damage the progress he's made, and the progress they've made as a team and as brothers. So I desperately hope Kripke doesn't go there.

ehab, I spoiler-fonted out that phrase in your post, and I think it might need deleting, although everyone at the cons seem to have been really careful about spoilery material that I've seen.

Sorry about that, I deleted the con stuff.

And I'd prefer the boys have a clever plan that works.
