Rewrite: Moon and Terra ending In the anime ending of Rewrite season 2 (Moon and Terra) did the girls summon Kotarou as their familiar knowing who he is/was? They were still childs when he was around them trying to save the earth. When he brought them to the moon, to the Kagari of season 1 did the girls remember their past lives or alternate routes? Can someone explain the ending to me, I'm not sure whether it was a good or bad ending. He completed his initial objective, but was that a good thing in order to fullfil his promise? 

It are a lot questions but they are all related to the ending of season 2, hence why I didn't make several threads for this but just one. I am not really into novels or mange (yes it's weird I know) so I'd appreciate it if someone could explain the ending. Up to the point where he thought that he couldn't kill her but chose to go against his own instinct I could follow the storyline, but after that it all felt kinda rushed and I think those only watching the anime might've missed out on a lot important information.
I think that the 2nd season closed off with a good ending. My reasons for it is that Koutarou had the same relationship with the key by the complete end, but they all seemed to be back to how they normally were, school clothes and all the other things. I don't know why but I got the feeling they gasped not just because the two kissed, but because they knew the two of them so it was even more of a surprise.

A bad ending in my eyes would have kept him dressed in his butler suit and not have the scene where they look to be casually chatting while walking on the path of light on their way to the moon.
