lol. i see your point esper
anyway. i think she has done quite abit as a female lead.. i mean.. helping lelouch when hes unable to be in two places at one time.. you know.. but karen seems to play a much more important role nearing to the end of season 1 and starting of 2.. such that c.c seems less important. yeah maybe she doesnt pilot and fight like the other soldiers of OotBk like karen (exception of gawin) but she did help lelouch in one way or the other.. like sensing nunnally was gone..
