I'm late to the party this time, but this was an amazing episode. I'm all for a combination of Ninth and Yuno fanservice... >_>.

Glad to see that Yuki actually decided something. Let's hope he continues to make actual decisions instead of becoming Shinji 2.0 (or _.0, if you consider all the Shinji-clones before this series).

@Bill: I'm thinking it's not as convoluted as it seems. Judging from the opening of episode 1, Yuki sacrifices himself for Yuno, so one would assume they hadn't actually consummated their relationship.

I'm actually going to toss out a new theory pulling from previous ones. Continuing with the "replay" scenario, Amano-Yuki did not know, or at least wasn't yandere for Yuki in the "original" game, but after Yuki saved her numerous times, or just by being with her, she started to become like she is now, thus the change from "Amano-kun" to "Yukkii". And then, as mentioned before, Yuki sacrifices himself for Yuno, and she becomes the new God of Spacetime; chooses to go back and try to change the past (whether being herself, and subsequently killing her past self, or as a clone) so she can be with Yuki. Thoughts? Most of it has been said before, but I wanted to touch upon the relationship change.
