Lack of Kallen in recent episodes has made me angry.
Either just come out and have her betray the BKs after her capture or have her be rescued. Don't leave us in suspense while you just completely forget to give us any info on her for two weeks Sunrise.
Also, don't pull the "hey lets hint at a relationship between her and Lelouch for half the second season then have her flip completely and go for Suzaku!" bullshit either.
But of course, seeing that Sunrise is made up of assholes, of course they'll do just that.
