Oh, good call Al. I was thinking to myself about where I've seen the twin-death-> replacement thing before, but I couldn't quite put my finger on it.
It feels like we're back to square one with the story in that we're trying to figure out what the heck's going on. Angel's not really an angel, and now we're left without an antagonist to drive things forward with.
I guess the weirdest thing that requires immediate addressing is how Kanade's staying in this word without rebelling.
Kanade's cute, but that doesn't stop the scene with a soaked Yuri being restrained being niiiice.
