I'm pretty sure he doesn't know. Suzaku has never said anything about it, and in the last episode Lelouche made some sort of comment about how he thought Suzaku was in the research division.Originally Posted by Budweineken
And interesting ep. Not really in the main plotline but still enjoyable. Oh, and I totally called Suzaku killing his father. Very interesting parallel with Lalouche. I hope this kills the whole Kira comparison, because Suzaku is obviously not just an innocent pacifist. Although he was very young and traumatized by the death he had witnessed so there are some mitigating circumstances. He probably didn't plan it either. Also explains why he is so committed to the idea of coexisting with Britannia. After killing your own father for a cause it's sort of hard to admit you were wrong later.
Also, where can I find this picture book or whatever?
