How exactly does this manifest?
I also wondered how dialogues work.
Please do not tell me that "companions" are (again) mindless drones without their own personality and you have to pick their dialogues answers for them.
You can talk to companions and ask from a set of questions about their backstory, or what you should do next, and they'll give a response.
They'll also (rarely) react to world events, giving their views on situations you find yourself in. But it's little more than the odd line of text or a small bit of backstory.
Not much in the way of chat or banter between the group.
