So when you're moving around, the world is empty, unless you trigger a cutscene that has a person talking to you, like you enter a room and they're there, or you do an action and they show up.

But they have to then exit, because of the "no humans in navigation mode" rule. So what do the animators do? They make it so EVERY CONVERSATION IN THE GAME ends with someone walking out. Usually them, sometimes you.

It's a silly thing, but once you see that they're doing it, you can't not see it, and it becomes increasingly hilarious. It's a whole game where people are constantly walking out on you and shutting the door behind them.
