- Diana's kindness to the other prisoners set the guards against her, fomenting a rebellion that gives Diana and her friends the chance to escape.
Natasha notes they've been on the prison planet approximately 4 and a half months before they escape.
H'Geln explains that the Kreel are currently all male, and change sex every century. At that point they will have offspring, become female, and hate everything male.
