Billie can't say she likes the sound of the mirror, either, which more or less prompts her to suggest, "Maybe you're just crazy."

Or maybe he isn't. The scale from the courier isn't an experience she can refute, though, which casts the rest in the unfortunate light of really being a thing. She should ask to see the mirror, but she won't or, more like, she really doesn't want to. Instead, she'll focus on what they have in common, meaning Billie turns around fully and takes a few steps over to close the gap between the two of them.

There really isn't anyone out here to eavesdrop but she'll humor Strange's worried glances around them.

"Was it a black scale? The one from your courier."
