I doubt Zeke is Lucifer. How would he have been able to get out of the Cage? He may be a follower though, or he may have some kind of other plans for leading a rebellion. It may be that Zeke is not Zeke, and Cas will know it's not him. I think maybe Zeke saving Cas' life, well, it could be because it's his brother, or it might be because he wanted to show Dean he could be trusted, you know, the way that Ruby showed Sam she could be trusted through helping them.

Sam is very forgiving, but with everything that is happening, I don't know how he's going to get past this one. I mean, what Dean is doing, it's stupid and reckless and just unbelievably underhanded.
