I don't know. I never expected the entire thing to happen, truthfully. I had guessed Fendros wouldn't accept her advances. 

Still, even if something like that happened, we would still be dealing with the business with Hircine and the other Daedra. Ahnasha would just be unable to do much in the way of fighting after a while. I suppose I should try and figure out if it is a good idea or not. At any rate, the story has taken a turn I did not expect.
