In Area 18, rebels attack Britannian forces with large tank-like Bamides mecha. The bulky Bamides become easy picking for the Gloucesters piloted by Andreas Darlton and Gilbert G.P. Guilford and led by Princess Cornelia Li Britannia in her custom unit. With Area 18 pacified, Cornelia plans to head to Area 11 and avenge Clovis by finding Zero. Lelouch returns home and is shocked to find the green haired girl making origami cranes with Nunnally. Nunnally says she was worried that Lelouch got caught up in the chaos created by Zero. She says that C.C. has come to visit Lelouch and wonders if she’s his girlfriend. C.C. says that their futures are intertwined, and Nunnally wonders if that means marriage. Lelouch drops a cup of tea and uses it as an excuse to pull C.C. out of the room. She asks him if he likes his new power, and he tells her that it’s pushed forward his plan to destroy Britannia. C.C. asks Lelouch if he thinks he can destroy Britannia with that power, and he explains that he was planning to do it without it. C.C. then goes to sleep in Lelouch’s bed and ignores his questions. Cecile reads news of a rise in terrorist attacks since Zero’s appearance. Jeremiah lost his position, and Britannia is in disarray. The JLF leadership wants to act immediately, but Tohdoh cautions against moving too quickly. C.C. asks Lelouch what orange means, and he explains that it’s just a meaningless remark, but it will make people analyze it and search for a meaning. Elsewhere, Suzaku is acquitted of Clovis’ murder due to lack of evidence. As he walks out of the building, he catches a girl jumping out of a window. He asks if something’s wrong, and she says she’s being chased by bad people. Kewell and the other Purists decide to do something about Jeremiah before Cornelia arrives. They don’t buy Jeremiah’s excuse about lost memories, and Viletta thinks about the soldiers in Shinjuku who lost memories, as well as herself. On the street, the girl introduces herself as Euphie. Suzaku asks if her story about being chased is a lie, but she’s playing with a black cat. Although it takes to her, it bites Suzaku on the finger. Lloyd and Cecile wait in a trailer truck and spot Suzaku with Euphie. The cat runs off, and when Suzaku asks Euphie why she lied, she asks him to show her around town. She tells him she wanted to see what sort of place Area 11 is because it’s her last day off. After seeing the town, Euphie asks Suzaku to take her to one last place: Shinjuku.
At the academy, Kallen sees Lelouch on a bench and asks if there’s any logs of the phone call in his bathroom. He says he doesn’t think there are, and he becomes unnerved when he sees C.C. walking around in his clothes. As Kallen begins to turn around, Lelouch suddenly grabs her and kisses her, which Shirley sees from across the lawn. Elsewhere, Bartley is flown out of Area 11 in restraints as a prisoner and regrets ever getting involved with C.C. Lelouch drags C.C. to a rooftop to ask what she’s doing, but she says she’ll be safe as long as she stays on school ground. C.C. sees a girl carving marks into a wall, and Lelouch explains that he placed a Geass on her to place that mark on the wall everyday. He mentions that he heard the world “Geass” during the contract. C.C. sees that he’s testing the length of Geass’ duration, and Lelouch says it’s best to know a weapon’s specs. At a memorial site, Suzaku tells Euphie that Shinjuku is finished after what happened. Jeremiah receives false information from a communications officer about Zero and heads to Shinjuku in his Sutherland. After the officer sends the information, Viletta enters the room and pulls a sword on him. Tamaki and two other punks argue with Britannian students, and Suzaku asks them to stop. Tamaki slaps Suzaku, knocking off his sunglasses and revealing his identity. Tamaki asks Suzaku if he’s even Japanese anymore and charges, but Suzaku flips him over his shoulder. Tamaki and the others leave, and the Britannian students yell at Suzaku for not finishing them off. Euphie slaps one of the students and says she won’t allow more insults. At the academy, Lelouch shows C.C. the results of his research: to use his Geass, he must make eye contact, he’s limited to about 270 meters and subjects experience temporary memory loss due to the Geass invading the cerebrum. Suzaku tells Euphie that he wants to create a world without war so that people don’t die in vain like his father did. A nearby stadium rocks from an explosion where Kewell and the Purists have set a trap for Jeremiah. Kewell says that they want to purge their shame before Cornelia arrives. Cecile and Lloyd pull up in the trailer to retrieve Suzaku, and he says he wants to use the chance to get battle data on the Lancelot. The four Sutherlands charge Jeremiah with lances, but Suzaku stops them with a slash harken. He pulls out his Maser Vibration Swords and cuts their slash harkens apart. Kewell charges at Jeremiah again, but Viletta jumps in and knocks him away. Euphie runs out into the stadium yelling for everyone to stop, and Kewell tosses a chaos bomb, which Suzaku blocks with his maser shields. Euphie steps forward and orders everyone to cease fighting under her authority as Princess Euphemia Li Britannia. Kewell and the others bend knee, and Suzaku apologizes for his rudeness. Euphemia asks Suzaku to help her so that others don’t have to suffer. Later, Euphemia meets Cornelia, who tells her to not do reckless things. At the academy, Lelouch is surprised when Suzaku appears as a new student.
Things are changing now that Zero has appeared on the world stage. Princess Cornelia has been sent in to take over Clovis’ position as Governor-General, and she wants Zero found. Because of Lelouch’s actions, the Empire is forced to drop the false charges against Suzaku. Suzaku has a rather strange encounter with “Euphie,” who turns out to be Princess Euphemia. The dissent inside Britannia continues as Kewell and the other Purists decide to execute Jeremiah and set a trap for him in Shinjuku. Jeremiah is saved by the most unlikely of people, Suzaku, with some help from Euphemia. C.C. appears in Lelouch’s life again, and although it’s seemingly an annoyance to him, she’s sticking around for the long term. This episode notably features C.C.’s first instance of eating Pizza Hut. Although Pizza Hut banners have appeared in previous episodes, C.C.’s obsession with Pizza Hut marks the beginning of many product placement shots.
