The Ragnarök Connection (episode)

The Ragnarök Connection is the twenty-first episode of Code Geass: Lelouch of the Rebellion R2.

Summary
Within the Sword of Akasha, Lelouch learns the truth of his mother's death from the Emperor and Marianne herself. They reveal their intention and initiate Ragnarök and Lelouch almost reconciles with them, but changes his mind upon realizing the world the Emperor desires has no future. Evolving his Geass to its next level, Lelouch defeats his father with the help of the collective unconscious mind of humanity, the personification of the "gods" the Emperor sought to defeat, dissolving his parents from existence. One month later, with Ragnarök prevented, Lelouch seizes the throne as the new Emperor of Britannia with the aid of Suzaku and C.C, and uses his Geass to make all dissenters in the court acknowledge him as such.
