Did he actually say he loved C.C. that episode?
I've always been partial to a Kallen end myself, but I never really had a problem with LelouchxC.C. either. But doing it this way just makes me upset. I like LelouchxC.C. for the fact that they were two partners in crime who grew fond of each other due to proximity and witty banter. Lelouch realizing he cares for her after seeing her after seeing how shitty her life was is not what I wanted.
I can't really explain it, I just don't like it being developed this way.
