starryburst pointed this out. Spoilers so don't read if you haven't seen ep 19
Like I said starryburst pointed out Rollo was never geassed by Lelouch. wanted to KILL him, we all knew he really wanted Rollo to die
And always did this plans to destroy him but he never geassed him to kill himself. I'm starting to think he never wanted Rollo Dead unconsiously. Anyone other speculations?
