A tall floating woman...

[If Sunday has any better guess, he might guess that it was a vampire that kidnapped his sister. But that is not an observation that he can give up to Aether. Not now.]

If I had lost my sister in the same way, I would do anything in my power to get her back. [Even ugly, bloody things.] I do hope that you find her... And that you find the answers you want.

[He is curious...]

You don't seem the arrogant type...
