Episode was fantastic! I knew colt would not kill Lucifer(but did not know that it can slow him down for a few seconds)!I almost cried when Jo and Ellen said farewell to Sam and Dean!Im assuming that the colt cant kill Angels and horsemen's of the apocalypse!Also im guessing that Sam&Dean will have to kill War,Death,And Famine(I think they will not kill Jesse).But there is a problem....how to kill death?! This episode clearly states that Sam&Dean will have to say yes to Lucifer&Michael! I have a theory that Jesse will be the one who puts and end to other three horsemen!

Supernatural's 100th episode coming up in March/April time and its a big one for Jensen! Could that be because Dean is going to say YES to Michael and Jensen will undergo a whole character labotomy?!

Maybe maybe not we shall see....Lucifer said to Sam that he will say yes to him in Detroit.After that Dean will surely say yes to Michael(probably in that upcoming episode in April).

I'm thinking Dean is going to say Yes first! six months from now roughly coincides with the finale. Dean says Yes first hoping to kill Lucifer before Sam can say yes maybe even thinking it will spare him having to do so. I think Sam will say Yes after Dean if Michael cant stopLucifer without him being in his true vessel or Sam caves because he is now all alone Dean having said yes already!

I have a pretty good theroy what if both says yes, in the fight both micheal and lucifer become weak and sam and dean will find a way to kinda break free and use there bodies kinda!!!!! but that prob wont happen but another one is that Bobby kills Lucifer proving that he aint usless!!!! idk tho

Lol....Bobby the world hero.I dont think that's gonna happen!I say that there will be the fight between Michael and Lucifer. I am just curious on one thing.how the !$#!# will Sam and Dean defeat the horsemen?!

idk they got rid of war already maybe they cant kill death but bring it back alive! get what i am saying! and also if you think bout it bobby has always help/solve the conflicts between they boys wouldnt this be the same concept and think he could throw books at them and say that one speech bout family (that he gave to dean in season 4) to micheal and lucifer

1.I think Bobby is going to die between now and the fianlly 2. Castial is going to die too 3. Michael is the only one who can stop Lucifer 4. the fianlly takes place roughly 6 months from now in real time (not ccounting for the passing of time on the show though usually its quite acurate), Sam says yes in six months time. This tells me Sam will only say yes to Lucifer for the finally ! 5. Dean says Yes first, because he thinks he can end the war before Lucifer gets Sam to say Yes! 6. Lucifer can not be killed only put back in his cage! 7. Sam and Dean will not die!

Michael the healer, will he be the one to get Bobby back on his feet? I read somehwere that the arc angel Michael is a healer I wonder if they'll use this to give Bobby his ability to walk?
