And yeah, it makes a plot where Lena has feelings for slutty Holly who will instead sneak into Ian's bedroom and bang him quite hillarious. Though obv. not for Lena.
This potential play option also underlines something else we can find out during the game and had quite a number of hints for. Wild Holly definitely planned her journey to sluttiness and had specific goals in mind.
It becomes clear that wild Holly acted on the belief, how mistaken she was on it depends on how we play Ian, that Ian prefers wild, slutty girls as GF. (and her development in this direction is also more probable if e.g. Ivy and Lena are slutty themselves)
Considering that even the normal and shy versions of Ian are impressed by Holly´s new confidence, style and playfulness, she was not totally wrong.
In some earlier posts I theorised on some possibilities how slut Holly develops further after ch.12. It seems my theory that if Holly becomes a couple with Ian now, she either bottles her slut side up for the bedroom or develops her wild side further in conjunction with what Ian likes/can abide with, is strenghtened by the option above.
Slutty Holly definitely had fun becoming how she is now and it is certain that parts of her newfound wildness are here to stay, but she had a specific goal in mind.
