Oooh super awesome catch! Actually I did notice that in the episode and amid my Lelouch ramblings completely forgot to bring it up. Thank you so so much. It is a crucial piece of information. I didn't take it so far as to match it up with Urabe, which is another clever move. That could indeed throw a wrench in their potential reunion. I don't think Kallen quite does the tail-wagging anymore; I think she truly and honestly loves Lelouch. One-sided probably. So she'll be angry yes, as she should be, but I do hope she makes Lelouch tell her more about Geass.
