Well, Lelouch would remember this now, that the Doctor had some sort of way to get in through their security and into the very room they were in. Lelouch didn't expect that outcome, but it was surely one of them as he had to remind himself that there was many things that could happen that wouldn't be a normal thing back in his own world. It wasn't clear if the Doctor had some way to keep some sort of defense in his faction's territory, and even he didn't consider the possibility of there being multiple Doctors. With the tight times he had now, he had to be cautious with his choices and actions. "Ah...this makes things much simpler than it had to be," Lelouch said with a rather surprised tone, but kept that proper and mature tone he usually tries to replicate ever since he became Emperor. Even if he could risk an actual attack to occur within the capital of his Empire, it wouldn't be that effective as he hasn't even gotten a chance to deploy the Avalon or even the Damocles. So...all this would be a talking kind of thing, mind games. Yes, that was what he did best.

"Tell me, Doctor, since you were the one to bring up the idea towards my Empire, I would like to ask a question to get to know your ideals better. Of course, if that's fine with you," Lelouch said as he leaned back in his seat, his hand holding up his leaned over head but also it was a way to keep his hand near his contact lenses if Geass was applicable for this. Though, it seemed like those two that the Doctor had brought over seemed to be non-human, and Lelouch wasn't sure on how Geass would work on non-human. He did manage to use Geass on the collective unconscious, or otherwise known as the "Gods," so the young Emperor was unsure. While the discussion began, CC was silently sitting at the 'sidelines' of this discussion, hugging the Cheese-kun plush in her arms that would seem like it was some sort of security blanket for her. Though, at times she seemed to be fidgeting with the plush, but maybe she was just getting herself comfortable?
