I think they brought back Ketch to make fun of people always saying the villain survived no matter how definite they seem. Ketch got shot in the head, and he commented on Dean still "questioning his demise". Even though there was a clear reason why he survived his death.

And I forgot, Lucifer's almost powerless now. And now he's Asmodeus's prisoner alongside Castiel, so I'm still sure Asmodeus is the main villain this season. The only other character who seems like he might be is the alternate Michael, but now there's no way for him to get through. Unless of course Jack opens another rift, or Michael uses his own grace for another ritual. (Are Gabriel and Raphael still alive in the other world?)
