How does she get on your nerves? She's a great tank IF you give her good armor and some good weapons. And she's a great pack mule.
I don't like followers, and she annoys me in my house. She makes herself at home in my room constantly getting on and off the chair, moving my stuff, telling me to stop moving my own stuff, etc. I want to visit Dive Rock and use Unrelenting Force on her.
On topic, she may still be in Dragonsreach. She was there on my profiles until I talked to her after buying Breezehome.
