Yes, if she wasn't around they wouldn't have focused on the school so damn much, and maybe they wouldn't have had to kill her to get SOME of the story moving.
Sadly, this episode is so similar to HEY LET'S KILL MEER, it's disgusting. Killing of a character just for that cheap attempt at emotional impact, problem is we don't really give that much of a fuck about her.
At least I don't because I'm not interested in this high school drama crap. I am (or at least was) interested in the other stuff, but instead R2 gives me this clusterfuck.
What gets me the most is Orange...so he just joins the Black Knights, just like that? Is that all what all that 'holy shit it's orange' build up was for? So they could just have him join BK? Why even give him a Geass Canceller for a Geass if they were just going to throw him to Lulu? Just for a cheap way to multi-Guess people? What a load of crap.
