It won't be difficult for Charles to connect Viktor in here to Viktor in his body, no matter what it looks like, because psychic energy translates. He has a feeling for people. It doesn't require reading a mind for him to get impressions of a person, and he hopes that he will run into the physical manifestation at some point. His curiosity is certainly engaged.

"Perhaps one day you'll feel comfortable enough to talk about it in detail. I can't deny that as a scientist, I'm intrigued, but only if you want to." Charles knows that they only just met, so he's not pushing. It's placed there as a possibility for the future if Viktor decides to later, not as any particular expectation.

"Are you concerned about being in this world looking different? This is a strange enough experience as it is."
