What if Luke and Leia fugged before they found out they were related, and Leia was carrying Luke's unborn son on Endor when they found out about being siblings?
Ashamed and disgusted, Leia wanted to abort the baby, but since they were in the remote Ewok village on Endor with no medical tech at their disposal, she was forced undergo a primitive abortion procedure and it didn't take.
A barely human-inbred fetus was pulled from her womb, screeching so high pitched that it caused some of the Ewoks to turn on eachother. It was slapped against the side of a tree until the screaming fell silent. And there it was left laying, thought to be dead but reveling in its dark unnatural power. What if that failed abortion was Snoke?
