Corrected entry: How come Harland Williams' commander never grew any beard after eight months of hypersleep?
Corrected entry: How did they survive after Harland wastes all of their food?
Correction: All of the food wasn't eaten. It was said by Harland that they still had food, just not appetizing food (such as anchovy paste.)
Correction: If you notice carefully, you can see that nothing changes for either the commander or Julie. (Ulysses isn't shown.) It appears that they are frozen in time in their hypersleep.
