I'm genuinely interested to see how Sally reconciles her desire to have everyone live together in relative peace, and her peach-eyed sociopathic episodes.
Wow... that was a lot that wasn't explained... but then a lot that was vaguely explained. This author really makes the reader pay attention to details and piece together the characters' backstories themselves. Confusing when you're stuck reading volumes months apart, but a clever storytelling method.
But I like this new character. He's the perfect thing to introduce key bits of the mystery (especially where Sumeragi is concerned) and I'm glad we get to see Yuki again; he's a lovable goober.
