WHAT THE FUCK LELOUCH!? Just take Nunnally, Euphie and Karen to some desolate place that no-one will ever find, and love them tenderly or RAVAGE them, or whatever, and put C.C. in a continuous death machine, so that if she revives, she just dies again.
Goddamn, if I was Lulu I'd just be loving Karen, Euphie and Nunnally tenderly all day long. Fuck Japan. Fuck Britannia.
