Cheering Mao (episode)

Cheering Mao is the fifteenth episode of Code Geass: Lelouch of the Rebellion.

Summary
C.C. explains her history with Mao, and how his inability to turn his Geass off drove him insane. An injured Villetta wakes up in Ohgi's apartment and he discovers she has selective amnesia. C.C. leaves Lelouch to take care of Mao herself, but Mao gains the upper hand when he incapacitates her. Lelouch utilizes his intellect to fool Mao and rescue C.C. using Geass on the Britannian Police to surround and shoot Mao. Safe on a rooftop away from the scene, Lelouch reaffirms his contract with her, promising not to fall victim to his power as Mao did.
