Finnick's been waiting for Annie to ask him to go home, honestly. He's been watching her get more and more tired but he doesn't want to push her home if she doesn't want to go, so he's just been waiting for her to say something. The yawn doesn't come at all as a surprise, but the request for coffee instead of a request to leave makes him raise his eyebrows.

"No, I'm sorry love, I don't think so," he tells her. "I'm sure there are some shops close around here, though."
