Lulu is like a clone of Marianne.

Or like, you know, a son or something.

lol at the pic... well I think Nunnaly hair color and such takes after her father, while Lulu is clearly his mother's son. But lol at younger Cornelia and Ephuie. (especially Cornelia since looking at her, you can't tell that she'd grow up to be an asskicker, a hot one at that)

yea....you wonder how u get pink or purple when mixing blonde+black hair....

aren't Euphemia and Cornelia half-sisters?

Lelouch and Nunnally are from Marianne.
Euphemia and Cornelia are from another unnamed woman.
