Wow, so much sympathy for Rolo. While I wouldn't go as far to say he deserved it, I think he had something like this coming. .__. He lied and pretend to Lelouch for a year =(
As for how Lelouch manipulated him.... That was totally expected XD (well maybe not how, but the fact that he did, wasn't unexpected) I wouldn't be surprised if Lelouch starts to care for him later on in the series, but even then, it's never been beyond Lelouch to use people that he cared about to obtain his goals (He did kill Euphie, and tried to shoot at Suzaku in S1). I get the feeling Lelouch doesn't really care who he manipulates in order to achieve his goals, with the exception of Nunnally.
