Jeri is a wimp.
Although if Kes had been properly trained as a fully qualified slave girl, they wouldn't have to still keep punching her in the face when she frakks up.
Weeks is possible.
But note this.
No food no water on the surface.
It's a dead world.
In what half dead state would Kes have been in by the time she found the camp or someone from the Kazon camp found her?
It would be just weeks before she would be healthy enough to pick up a serving tray or clean a toilet.
Kazons have toilets?
Kazons use toilets?
Kazons use toilets well?
