Jennifer did such an excellent job as VA for Shadowheart in moments where she is genuinely disappointed, sad and insecure that I do not buy that she is meant to portray any of those things during the Halsin/Twins/Mizora scenes. The only thing she sounds remotely annoyed about during the Mizora thing is you not asking first, the others she positively encourages.
So no, I still think they're all just completely out of character. However, Halsin is perfect Orin bait if he's alive until he gets more act 3 story (which might never happen), drows can just be ignored like any other NPC in act 3 and Mizora.. well you brought it on yourself, you act out of character, she acts out of character.
