Alright, to properly address the OP - I believe I understand what you mean, but please correct me if I am wrong; the options that we get to deal with the snarky attitude with our companions is often... Lacking, at best. And it is not due to the companions itself - personally, I like the vast majority of them and I find their conversations entertaining in themselves, but I do agree with OP that the responses are often... Not very impressive. It is just our (in-)ability to properly respond to their behavior, regardless if we want to call them out for being confusing or behaving poorly (ahem, SH), simply tell them to "sit down" (although, you can do this with Lae'zel at times) or simply make a in-character decision to do something snarky back - like roll our eyes, laugh at them, give them a snarky comment or even just sighing, going like "Ugh, never mind" - aka. making an in-character decision that the game actually registers as us calling out their behavior.
Oh, I get that. 100%. It would be nothing short of amazing to see/hear SH's reaction if the game actually added an option to roll your eyes at her in-game. :'D
"You know where to find me should you decide to reinvent your taste of company."
"I just did, you're out, sweet heart."
"Shadowheart"
"Don't care."
Or that, that would be *HILARIOUS*. :'D
