Until a chance encounter 4 years later with Captain Levi Ackerman forces her to make a choice. Escape again, outside of wall Maria where the scouts can no longer reach her? Or return with Captain Levi to the walls, use her strength for the greater good, and cage the monster once more. Can Rhea allow herself the hope of redemption for her past sins? And maybe something...more?
