Jack raises his eyebrow as he watches her. Not at her getting the glass, because between Rapture's style of self-service and the absence of easily visible staff in the ship it seems only natural to get your own glass, but because uh, Jack's scale for what's good for drinking is definitely broken.

But he doesn't hesitate to reach over and pour her a glass when she holds it his way.

He had asked for the strongest thing they had, and needless to say, the drink has a sharp scent, something definitely not meant to be drunk on its own for any other reason than to get smashed as fast as possible.

Jack sets the bottle down and picks his own glass back up again, though he keeps an eye on her to see if she'll commit to this.
