This made me wonder, what happens to someone who is prevented from doing whatever they were commanded to?
Like if Lulu ordered that girl to mark the wall, then chained her up in the basement what would she do?
Chew off her arm to fulfill the geass'd command? Die?
I don't think this has come up in the show yet, so I'm willing to bet the writers will use this to do some retarded TWEEST.
Also, I can't see this girl as anything but Jun with implants.
