Wolfgang makes the effort to smile and feels like Wednesday Addams doing it. It feels like they have sixty teeth. Should they get up? They feel like they should get up but Michael's on the side closer to the door. Probably to escape more easily, which is unfair, since he could just fall into the shadow under the table or something. Wait, why are they thinking about escape? About 'getting through this'? He talks about this like they're here to get a root canal.
Their strained smile falters slightly. They're actually not sure they've ever heard Michael make a joke. They choose to politely skip over that comment, probably they misunderstood, happens all the time. “Hello. Is nice to meet you.” They're seated, which means their unusual height isn't immediately obvious, which means the first notable thing about them is their accent — not American.
It occurs to them they don't know which name to use, or how much about themself that is true to reveal. That's the problem with lies: you can't keep them straight forever.
Michael's sweaty hand is like a vise, it's a little uncomfortable actually, but they've never seen him this anxious either. They keep their hand where it is.
