Percy is done with doing the gods' dirty work. So after she defeats Gaea she moves to Star city and becomes a villain. She hates the Young Justice League because they remind her of her old life and she sets out to get rid of them. But when she gets captured by them and pretends to have memory loss, they try to reform her and make her a hero. She sees this as a golden opportunity to infiltrate the team and eventually she is put on the team. But when she starts to get attached and understand their ways, she decides to not kill them and instead join them for real. She doesn’t tell them that she’s faking amnesia but when an old enemy comes back to play, and she knows how to defeat him, will she risk getting kicked off the team and not being able to protect them anymore in trade for the truth and the way to get rid of the enemy, or will she risk all their lives to save her reputation and keep them from knowing the truth about her past?
