Maybe, it's possible. I'm not sure about it.
I will say, though, that as much as that one autist has tried to push fat Anne in these threads, I like the idea of fat Sasha a lot more. Even if she was never fat at any point back on Earth, the idea of her becoming fat gives me a boner. She did have an awful lot of food in her chambers in "Reunion," maybe if she'd stayed on as second-in-command of the toads she would have become obese, spoiled, and hoggish.
