Ariadne is going to take a moment to wonder why she didn't just graduate and stay graduated. New York is weird, but this shit is ridiculous. Then she is going to tuck the kitten in her bag, grab something vaguely shaped like a baseball bat, and figure out where the hell the boys ran off to. Because, really. Bullshit. So much bullshit.
Pasithea is going to assume this is largely nightmare-involved and would, if on campus at all, be at or close to the library anyway. This whole thing would be more creatively bothersome than genuinely worrying. Unless something is attacking her. Then she will yelp like a girl and kick it in the face.
Dude, Coyote has read the books on this shit. She is so apocalyptically-prepared it isn't even funny. She will, however, want to make sure that her Minions and the tiny little baby-things are okay. And then she'll probably go hang out with Charon. (Even though, man. The urge to bust skulls. It is so great. When else will you get this type of opportunity?) But no. Henry. She'll just kill shit on the way over.
And Nanna is going to be simultaneously very glad that her father left and very distressed that her father left. She doesn't want him to make her leave - okay, a little right now, but not completely or forever or anything - but holy shit monsters. This was not in the brochure.
