The descent into madness.
Lelouch shows what happens when your motivations are founded on a shallow foundation. He has to come face to face with cognitive dissonance: he wanted to create a world for Nunnally, but Nunnally had her own ideas. He has sunk below where he was when he was just a bored student. Instead of taking risks with adults, he tries to relive the good times with Refrain. He also uses his geass for the enjoyment of bullying other people. Lelouch has no moral code that keeps him from being completely selfish except the ideal that Nunnally sets before him. Lelouch’s new motive is not much stronger than his one based on Nunnally. He is enemies with two of his old friends and Rolo is going to be a problem. Lelouch’s intelligence is not going to keep him from flipping out again. He knows has to maneuver within his motivations for his sister and friends, which will make it hard for him to solve anything.
His advances on Kallen shows something interesting. He was interested in creating a safe world for his sister. But when he no longer had the comfort of his sister, he reached for physical comfort from Kallen. Lelouch knew that Shirley liked him and one would assume that he would have gotten physical affection from C.C. if he pushed for it. But instead, he looks to Kallen. Perhaps it is because she is the one person who knows who he is, and does not have a contract with like C.C. It will be interesting to see how their relationship will proceed. If they act like they always have, then the writers are missing an important relationship to explore.
Despite there not being as much action in this episode, it is important for the story. The parameters for Lelouch’s actions are being set. He cannot hurt Nunnally, but he is not going to sacrifice the Black Knights. He will not abandon his goals against the emperor, but he is also going to have to work for the Britannians at his school. The stage is being set for an interesting story.
The ocean farting is also awesome.
