I cannot remember the exact deets, but I remember having a pretty interesting interaction between multiple NPC's. Basically I poisoned some random drink, which turned out to belong to someone working behind the scenes for the runway models. He had to dive out mid-show and go be sick, but the "main guy" (always forget his name) was not all too fond of this at all. He started shouting at him, making fun of him, etc. Which was followed by his co-workers laughing at him. I then later caught him sitting outside on some bench crying to himself, putting him out of rotation for the rest of the level. I thought this was some great attention to detail, I'm sure there's a bunch of little things like this that I still haven't stumbled upon. Hopefully it continues throughout all the rest of the maps/levels.
