Something that felt natural but I didn't think about much at the time: throwing a drink is an act of anger, yet in this sequence Eve looks completely fearful of what she's doing. She doesn't have the confidence to back up her aggression, and most likely would've crumbled in apology if Park hadn't reacted the way he did. Up until he reveals his lack of cultural awareness, she still holds him in high regard and can't walk away. It's sort of a gift that she gets it out of him, for both of them - they finally have their answer.
The final visual was mostly lost in the bigger, more enticing discussion of their roles, but I still like the duality. Eve is either laughing or crying, and the $50 is either pathetic and irrelevant, or the basis of a formal, transactional meeting.
