[This is easily one of the more revealing things he's heard Larus say in the time since they met. ("But you know that just as well as I do.") He's come to know that Larus has a hard edge, but this is something else. Something more. There's a chilly kind of rationalism here that only comes from someone seeing something harsh, or having something harsh done to them.

There's the obvious possibility, but it's something that's hard to guess at easily without it coming from the other man himself.

Dorian frowns, mulling over the thought until Larus distracts him.]

I wasn't being overwhelmed with options for protecting my picture, and Grayson impressed me. [His tone has a note of 'You weren't there, Larus'.] He demonstrated his magic, proved that he could satisfy my needs, and I chose.

I can tell he's hiding something, but... [There's something there, too. His meeting with Grayson had the feeling of being a masked man in the presence of someone wearing something very similar. Someone very comfortable and experienced in the art of hiding the relevant. He's sure he saw more peeking out from beneath more than once. It's a potential warning sign, but not one without attendant charms and intrigue.] I can't say what. [Yet.]

But yes, he's some kind of sorcerer. Probably more.
