Snowman's been quietly stalking this, watching him interact with the Prospitian and the human for awhile. He's clearly not her Jack, or rather her Slick, because well let's see no Dersite from her session would be caught dead in something that colorful, first of all.
And then there's the whole thing with PM, that's also a thing that makes it obvious.
So despite this not being the little bastard she had spent centuries torturing on a dead planet, it's at least some sort of substitute. And fortunately for her, she's already spoken to PM about the fate of that session's Black King and Queen.
By which I mean it's time for her to fuck with him a little are you ready okok]
