To Annabeth: What would you do if Percy had interest in another girl?

Annabeth: No... No. Just, no. 

Percy: Annabeth's jealous of my sassiness. It tends to attract girls.

Annabeth: Percy, I swear, there's no help for you.

Percy: Jealous, I tell you.

Annabeth: Oh my gods, Percy, I'm not jealous of you.

Aphrodite: Definitely jealous.
