The drug commentary makes me THINK, because. I mean, outside interference is the only thing that kept Lelouch from actually using illegal drugs in his canon. He was at a super low point, and it was a special drug that supposedly causes you to hallucinate memories from ~happier times~ (I'm sure it's more random than that in practice, but this is the idea), but. Would he try something, if given the opportunity? :|a
I imagine he'll at least consider it, so I will smoosh him into Kija's accidentally-experimenting vicinity.
