I don't know... that whole sequence with the flashback to Narita, after Shirley mentions the railcar, seems to make Lelouch's subsequent words feel completely out of guilt. The way he dodges her questions, too, by mentioning the others following them, seems to make it feel like he's just trying to make it up to her, nothing more. Anyway, a quick summary:
Spoiler for Summary??!:
1. Lelouch tricks Rollo by having C.C. perform and calls him, using Villeta to further confuse Rollo.
2. Kallen thinks Zero is Lelouch, but C.C. reveals herself. The two have a talk and it looks like C.C. and Kallen on much friendlier terms, though Kallen looks a little jealous.
3. Lelouch the house-wife... Milly the evil slave driver.
4. Lelouch wonders about Nunally, his face shows the worry but he keeps it hidden.
5. Viletta and her crew? discuss Zero, Lelouch, and C.C..
6. EU gets owned by the White Shinigami, Suzaku and the Lancelot.
