Anna sets about mingling as soon as they arrive. Kristoff's managed to get a nice house in the Hamptons – a coworker's, apparently, who's on holiday in Florida. It's almost 9pm when they arrive, just because the drive took so long.

"You don't mind if I drink, do you?" she asks, about ten minutes into the party. "Kristoff said we can stay here in the spare room..."

Elsa doesn't mind at all. It is a party. "Just don't go too crazy," she says. Anna gives a bashful grin before she leaves for the kitchen.
