That does sound good. Maybe her father was a big man so she could wash his clothes, so he could wear those clothes for a bit. And it would be fun to have it that he never really had a shower or rain. I think that living on a spaceship would make it that they don't use water all that much for other things than to drink it. 

Maybe she can even get his device while he is out. But he would have to know the code to get back inside though. And he would have to know where to go to get inside.
