The Fell Children
children - a set of triplets and a set of twins.  Despite the five child sharing two birthdays, It's possible
that none of the children share a father.  This is due to the physiology of their lepron mother.  

Unlike their pure human counterparts, lepron females have no set estrous cycle.  Instead they are
induced ovulators, releasing their egg after coitus.  This means that an egg is released after mating,
and these eggs remain viable for up to fifteen days after release.  If fertilized, each of the eggs is
capable of implanting in the uterine wall.  Since an egg is released each time that they mate and each
egg can implant, is it possible for a single lepron female to carry multiple children from multiple mates
to term at roughly the same time.  While tests could be performed to determine who is the father of
each child, at this point, it doesn't matter to anyone involved.  Each member of the crew has stepped
up to help raise the children.  Somewhat surprisingly, this even includes DeeCee who has stepped
up and done her part to help.
