I'm also a fan of luluxcc. I do hope more will happen between the two. I mean, she did kiss him in season 1, and when she dropped him off after the kiss he smiled and told her not to die.
and in R2 when lulu got his memories back it was all about CC, but to have all these kallenxlulu moments seem really random and odd. It's like.. what happened to luluxcc that was happening before. Ugh.. Code Geass you confuse me.
