He's not entirely sure how well Reira's thought this through. But it makes her happy so he should let her do it? But she'll get herself in trouble if she does do it.

At her question, he shakes his head slightly. "They just don't see me. There's a difference." Someone becoming invisible means that everyone can't see them. If Cole makes it so that some people can't see him, then this means that others can.

"Some people need to see me, so I make it that they do. Most don't."
