Anna had tried her very best to be the best maid that she could to the people on the TARDIS, and John specifically. Still, she knew that he was frustrated with her. Of course it didn't help that he didn't ask her to help with things. If he asked her to take on more responsibilities, she would have done so. She didn't know about Martha, but would have been understanding if she had known about her.
The thing was, was that she always lived up to a code and that code had to be respected. She wouldn't talk unless he asked her to talk. She wouldn't do something out of the ordinary until he asked her to for the most part. Still, she was the only one cleaning in the TARDIS, she was quite sure about that. The amount of laundry she did was almost unbearable.
Coming around the corner, she smelled something awful burning from the kitchen and poked her head in. "Are you all right, sir?" she asked quietly.
