If there's anything that makes Booker nervous, it's gatherings like these. He's always lacked the social graces and patience that they require and honestly, if he hadn't felt obligated, he'd never have some in the first place. But Sybil's someone Elizabeth likes and he has to admit she wasn't totally useless when they were all trapped in that... well, wherever they'd been trapped.

Still, it doesn't stop him from standing in the back of the room, drinking from the flask he always has on him.
