I highly disagree on the whole "create another female character and use her as a breeding device" plot. That happened with Kelly Kline and I absolutely hated it... Although that would be possible because Buckleming is still a thing and they love that kind of crap.

If anyone's saving the angels, it's very possible that it would be Cas. Or maybe it could be Cosmic Entity. My thinking is that when Cas woke up in The Empty, a lot of angels woke up as well so maybe Cosmic Entity will just throw them back to Earth or something. I definitely think the whole "The Empty/Cosmic Entity" plot isn't done.

I agree on Jack taking over Heaven by the end of the series. I doubt the writers will kill him off since he's already loved by the fandom.

If the rumors are true and our Michael will come back on episode 12 (the episode Rowena comes back), then he's also a candidate for the Ruler of Heaven.
