Playing through the other day, I noticed how antagonistic MacCready and Nick are towards each other when you swap off companions between them. MacCready makes some comment about getting an oil can or something to Nick, and Nick replies in a dry tone, "Thought that up all by yourself, MacCready?" or something to that effect. Clearly, the two dislike each other.

What other companions have you noticed seem to have something similar? I didn't notice it for anyone else, but then I haven't switched between everyone in all possible combinations, yet.

I know Hancock and MacCready are cool with each other, and Nick says nothing when you swap him and Strong. Deacon seems to be okay with Curie, and Curie was a little hurt when I swapped her for Cait. Danse doesn't seem to comment at all when you swap him with anyone, as far as I can tell.

There is a video up that shows all companion swap lines that will give you what your after


Besides those, companions don't seem to interact with each other much.

FluffyLamaNinja(I think that's her name) has a video of all the companion interactions.

It's Fluffy"Ninja"Lama bruh
