I definitely want to tag all three of the first names on your list. Maybe particularly Reid and Aidan, since a more relaxed Lelouch might have feelings to express, re: Euphie and their living situation, re: having met Reid before..... and as I said of Mal, the atmosphere will be great for Lelouch getting over his sulk at everyone who threw water balloons at him or, in Chuck's case, just suggested he should go soak his head. ;D
