Mao + Lulu
Hmm.
Hrmn.
AHEM.
I'm just really not sure how to start on Mao's end. He just got shot up by like twenty people at the point where he tries to kidnap Nunally. Any time before that has him being all THE CRAZY and so forth.
Could always switch the plot around and have Mao come in at a seperate point. I mean, really, deducting him from the plot does not change much, as he was a token device to show that Lelouch's powers would eventually start to consume him as well. Well...other than the whole making Shirley CCRAAAZZZZYYYYY thing.
