I hope they at least tell Mary about Adam, it would be fair, but then again, it's best to let Mary keep her memory of John untainted. Whatever John went through after she died, Mary is going to blame herself for them.

I don't think Michael will come back acting all crazy. If he does come back, it would be more like Castiel in season 7.

I also don't think it is possible to run out of ideas for Supernatural. A single person can make up a dozen different headcanons based on one topic, at least, that's my experience.

I'm a Michael-fan, so I do want him back, but it just doesn't sound possible. Who knows?
