I think this is overall pretty good. There's some style tweaks I would make, below, but the writing works. I have two main comments: I think a lot of the dialogue is trying to be a bit too hard to be smarmy/clever, and I think the encounter with Claire needs to be lengthened and explored more: it feels like it should be the heart of the piece, but it also gets brushed over pretty quickly, almost feeling like it's not entirely there. Other than that, I like the setting and mood you've created, and the characterization is quite strong. Pretty good overall.

Just "patiently waiting".
Her eyes had, once the Great Shift occurred, been a beautiful hazel, now completely clouded over like watered-down milk. It was the first of the changes that happened to her. Even now, he could see the strands of white spilling into her hair, a material reminder of what was taken from her.
I'm confused by the timeline this is indicating. The Great Shift turned her eyes hazel, and then clouded them over? It seems more natural for them to be hazel before right?

Is dialogue missing here?
