I'd assume it's about companions. A bitter rivalry with your companion is going to be far more interesting than just some NPC and it's a concept I personally adore.
Party dialogues, whenever they come out, will probably clear this up a bit, one way or the other.

Edit: Didn't see the post right above me, that's pretty great news!
