J'onn starts following M'gann so as to protect her. Armek, her former mate, comes to Earth with orders to take her back to Mars for execution, and gives her two hours to surrender before he goes after her friends. Fearful, J'onn decides to bring her to the DEO for protection. The real M'gann shows up, revealing the other one to be Armek in disguise, forcing J'onn to put the DEO into lockdown. Assuming Winn's identity, Armek initiates a meltdown in the building's nuclear reactor, while another White Martian posing as Alex ambushes Kara. J'onn and M'gann free the real Winn and Alex and confront Armek, killing him with a metal pole. Winn fixes the reactor in time, and Alex helps Kara subdue the other Martian. Afterwards, M'gann informs J'onn that she intends to return to her home planet in order to reform her people. Encouraged by Alex, Kara tries to ask Mon out on a date, only to find that he already has a relationship with Eve.
