Yes, that's what I'm thinking. I don't quite know how I would feel about it if it turned to be true. But the possibility is certainly there, especially when I think Michael might be MIA at the moment. Otherwise even Dean doesn't say no, Michael can at least rides another vessel a la Lucifer is doing at the moment. So what if Michael isn't at his full strength. It's not like Lucifer was at his either.

Btw, I forgot to say I too wish to see JDM come back, even for a brief moment. Yes, he has such intense chemistry with Jensen. In fact, for a brief second toward the end of this ep, I thought he just might show up, and then I was all horrified thinking Sam or Dean would have to chop off "John's" head!
