Copypasta from the last thread:
"Heres what will happen.
Kallen will be killed in the second to last episode. C.C. will be missing and Lelouch will be all alone. Lelouch will then run off to the Imperial villa to confront his past. When he arrives, he will casually kick a grenade in the direction of the guards, killing them and setting into motion a great gun battle as he ascends through the Imperial villa toward the Sword of Akasha at its summit. On the final leg of his ascent, he will encounter his brother Schneizel who will unlock the final gate for him before being shot by the last remaining guards. He will tell Lelouch as he is dying that he was "waiting for him to come back and take over," and then expire. Lelouch will reach the Sword of Akasha as an explosion seals the passage behind him. Leaving him alone with Suzaku.
Suzaku, having assassinated the Emperor and taken his position, will be waiting for Lelouch, and the climatic final battle between two former best friends and comrades shall commence. In the end, it will come down to both of them tossing their disarmed weapons back at each other and shooting one another at the same instant. Suzaku dies instantly, and Lelouch has just enough time to contemplate his life before he too, dies on the steps of the Sword of Akasha.
Afterward Rollo walks casually to Lelouch's corpse and tells his dead "brother" that he "made a good clown," and that it was because "he talked so loud" that his actions were "so small." A smiling C.C. walks out of the shadows behind Rollo and looks at him with affection.
