Thalia Grace
Halfway through the battle, she along with Lit, Calypso and Josephine stood by as Commodus had Emmie, Leo and Georgie hostage. Apollo asks her to stand down before he goes not his Divine Form and blinds the emperor. She takes out one of his guards and searched the surrounding area for Commodus with no results. After that, she sits with everybody and discuss about the prophecy revealed by Meg, saying that the Hunters can't help because they just have one mission to finish.
