I was just about to write a post ranting about how often the AI insists on having "bully" characters constantly insert themselves into whatever story you're playing.
(Disabled girl with a barely functional wheelchair? Better make sure to have Marcus literally following you around school harassing her)
I just figured out how to get them to go away. You can basically control the NPCs by putting instructions for them in starred text.
Feel free to copy and paste this in a story if you want.
**Suddenly Marcus blinked out of existence and evaporated, all memory of him and his friends erasing itself from everyone's minds as though he never existed. We continue on with our pleasant night as though we had never been interrupted in the first place**
