Thuke is the real tragic romance that Aphrodite was talking about. I mean seriously, Percabeth ends happily ever after. They kiss in an underwater bubble. On the other hand, Luke dies and thalia becomes an immortal virgin. Which one sounds mais like a typical Romeo and Juliet scenario (not that Luke would ever wear tights or not climb up a balcony.) Maybe Luke will end up being reborn and then him and thalia can live happily ever after. That is if Artemis does not turn him into a jackelope or if she does not accept her lieutenant's resignation.
