Alright. [He won't argue. He's not here to make her uncomfortable, after all, it was his idea to come up here.]

I worked it out by the end. I'd show you, but it's not Cordis right now.

[It's not that he can hear her thoughts at least, just that he was thinking similarly.]

Alright. It might be for the best actually.

[When she sits down, he nods at her with a grin, before moving a little farther away so that she's get a full view of the show, but also so that she won't be too disoriented when he takes his masks and suddenly removes it.]

Satanael!

[A burst of bluish energy explodes from around him, bluish flames rising up but the effect seems to be mostly for effect can actual heat. A burst of wind from all directions, and a grandiose figure materializes behind him, floating as all six wings open up.

The flames never leaving Joker's face, the figure itself moves forward to give her a small, of dramatic bow, almost echoing his movements.]

That is Satanael, one of my other selves.

[It extends a hand? claw? In greeting. Despite being nearly twice the height of the person who summoned him, it appears to be quite a gentleman.]
