Yay! James is real tactile, so he'd have been hugging and slinging his arms around Harry and ruffling his hair (this is not really new but a little more excessive than usual) and praising him all night. And he might've headed back with them, since he's still kinda hurty, and gone to bed.
LOL. Katniss would've been like, okay, ONE DANCE. ONE. And she would've held to that, but she enjoyed it in spite of herself. Annie is happy to dance as much as Johanna would like.
