[Someone's sounding vaguely distracted] Hey Finnick, you've taken girls out to fancy restaurants before, right? [Just. Making assumptions here]

[Uhhhhhh.] I've had expensive dinners with people before. [That's basically the same.] Why?

[He'll take it! Also the distinction kind of goes over his head] Jack got me'n Annabeth reservations at some really nice place and - well, the last time we went somewhere like that, I literally had a god to help me out. And I'm trying to keep it a secret from her too, so...I don't really know what to do.

Blindfold her and tell her it's a surprise. Girls like that sort of thing. [Being blindfolded and surprised, that is.] You could make a game out of it. [Also... is Percy comparing him to a god right now? Hmmm.]
