Strange can't help but nod approvingly as Christine shows him what he's guessing is a living area. As he looks over the bookcases, he can't help but smile. His house is the same in that regard.

"Normally, I'd suggest the kitchen as that would have more natural light and some windows you could open should the experiment go wrong, but I honestly don't know how much natural light a house inside a tree could have to begin with."

It's an honest question. If the window was open, would that dispel the illusion? Could sunlight penetrate illusions? Strange is full of questions about the theory of Christine's illusion magic, but he's keeping his mouth shut for the moment. He can lob questions at her after she chimes in.
