Alex: *chuckles* Pizza has a magic all its own I swear. I have never met anyone who doesn't like it. 

Clary: *smiles a bit and gets up, pulling him him up with her* Come on let's go find something to eat, I'm starving. 

Billie: *nods, and leans her head against his shoulder* I was there for five minutes, long enough for Alex to reassure me that he had it covered and then I went back to our dorm and drank. *Storm runs over towards them, sitting in front of them* He wants you to pet him.

I see Billie having completely shut off for a while, and God did the demons hate it. However, it's why they respect her authority. Poor Lo tho.
