Yes, that's true about companions. They sometimes say one-liner about currently finished\upcoming task, and have a bit of banter between themselves on the move, but i wish i could just have more conversations about random subjects with them.
It also felt weird that Laizel kept yelling her queeen's name in combat even after deciding to turn back on her... I don't think that in game where every random npc has voiced lines it would be problematic to change her combat responces accordingly.
