To be fair, episode seven had a scene where Tahno looks very battered and pitiable, far from his former immaculately groomed self, and is much nicer, friendlier and more polite to Korra into the bargain. So Tahnorra shippers aren't explicitly sunk yet. In fact, they're better off than they were a week ago.
Also, the situation with poor Asami and her Dad? Insert 'BRB tearbending' gif here.
