Surprised no one beat me to this.
I think they've got the characterization of MB down. I definitely sympathize with being the introvert in a room full of extraverts. I remember having to play white noise in my ears in the break room when I worked at staples. One guy almost lost his phone when he kept trying to shove some meme in my face.
anyways. It's been a while since I listened to the audiobooks so I don't actually quite remember where this is exactly going so that's neat.
My one complaint is that honestly... they made him too easily pass for human. The books made it clear that you could tell he wasn't quite human.
