Oh my god as Bella would have said when she was young !!
I have seen so many crazy theories in those last pages that i start to loose my mind.
Really people seem to find 10 times more stuff than there is really in this game.
The game story and script is quite simple in fact, they only mysteries really existing are about Quinn (who is she and where does she come from) and Bella husband and her locked room and Finally Lana and how she died mabe!.
All other girls are written in a simple way, Josy and Maya are just good girls from a middle class family, Sage is the daughter of a businessman, Jill is a Royce overprotected girl living outside of the real world.
Apart from Bella and her mysterious husband and her realtion with Jill, two things that seem connected and that locked room with maybe a momified husband or a caged husband, i don't see anything special with those girls and no reasons to get crazy with over the top theories!!
