I was thinking of creating a werewolf character and having Aela as a wife, but this quote that she gains when Dawnguard is present in your game is a bit annoying, because she just constantly repeats it when you're standing remotely close to her. Does she go back to her normal dialogue if you complete Dawnguard's main quest?

She didn't in my game. I completed both the Companions and Dawnguard and that's still all she says, every 5 seconds. I ended up marrying Sylgja because of it.

A small bug in her dialogue renders her unable to complete her explanation of the new werewolf perk tree.
