Honestly, I don't remember very much from the rest of the episode, other than Lucifer being awesome.
I also may stop watching the show until we know for sure when Castiel will be back, and catch up then. Not because I don't like it any more - I'm actually sure that it was a pretty good episode - but because I'm afraid I won't be able to watch it properly, the way it deserves to be watched, while I'm so busy worrying about my angel and waiting for his return.
I honestly don't know yet.
