I have the impression that Alexis wasn't supposed to be a LI at the beginning of development, but her storyline ended up changing at the request of the backers. However, my memory is always faulty, and I might be confusing her with someone else. Can anyone confirm this?
yes, it grew organically!
that is why quite a few things had to be ret con for her to fit in perfectly and not be just a slut who jumps a guy on an airplane bathroom!
also why her caracther is so sexually charged at the start!
she was suposed to be the sexscapade to keep the dudes interested until the story grew enough for the LI`s to takeover after the relationship build!
as for Nikki and Cara Nikki should have died in the car during their jogging!
thus the MC would leave and Andres could confort her mother
while still having a sort of Incest without it being Incest...
it would also cover the redhead and the virgin fetishes!
