V.V is going to reveal that he caused Lelouch's geass to go crazy, Lelouch will take advantage of this and neglect to mention that even with him no longer being in control of it's activation he was still being a dumb shit by saying what he did.
V.V escapes when Orange-kun manages to recover from his wounds and get to a Knightmare. Cornellia joins up with the Black Knights.
Her defection causes a cival war within the Britainians. 10/90 split in favor of the emperor.
This still gives Lelouch enough time to rally the Chinese and the EU agains tthe Brittainian forces., who begin a massive crusade into the heart of Britainia iteself to strike at the emperor and end the war.
Cut to the end of the epic battle fueled by plot device and insane flips. The Emperor is dead by Lelouch's hands and the world seems to be settling down.
