I think that Dean and Sam will say yes at the second to last episode at the same time so in the season finale they will fight but figure a way to stop themselves!!!! Like Bobby did in season 5 episode1!

I don't know I think Cas will find god and save the day Sam and Dean can't say Yes, because they won't be able to stop from killing each other.

I think this is the big 'brother' conflict the series has been leading to since Season 1.

Kripke promised to reconcile the brothers this season; I don't know if there getting together for Dean to stop Sam from saying "yes" counts. If they do say yes; it probably won't be for awhile. Kripke also sais that the humans were supposed to be the heros so maybe Dean will find a way to kill Lucifer and keep his humanity.

I hope so, Jared is so sexy as Lucifer!

God, I am afraid so... yes

If Sam says yes to Lucifer first, I think that Dean will say yes too, in order to stop Lucifer/Sam.

No, I do not think that either of the boys will say yes, because it would no longer be Dean & Sam. Because as Eric has mentioned that humans are the heros of the show. I think they will find a way from letting that happen. And they still have some reconiling to do, Sam coming back is only the first step. I definitly don't think Dean will say yes, because he has seen what happens to the human vessel & knows that thousands of lives will be destroyed if he does that & he is all about saving the innocents, finding ways around it so that does not happen. Also, as long as Sam is w/him, then he has stronger chance of not letting the future Zachariah showed him come true. As he said, they are going to make their own future.

I'm hoping that they will try and say yes....as a self sacrifice but somehow Cass finds God. I would think that maybe if the boys were willing to die to save the world...that it would give God what he needs to kill Lucifer. I mean, if he created Lucifer, he should be able to destroy him right? Also, if that happened, it could be a giant reset for the whole show....no Lucifer...they could start a new life and we could get a season 6? LOL

No I dont think either will because they are both tired of angels and demons messing with their lives.
