You know, Kallen/Lulu is my favorite pairing, but I liked shirley too as a character and about his love toward Lelouch. Her love was really sincere. I'm sad because the last scene is so....... after this I think if I had the choice, i would have wanted her to live and be with Lelouch.
Rolo is really evil. Now it's sure he has already planned to kill Nunnaly if he can be near her.
