Not sure what you mean that it creates a continuity issue... Claire doesn't like her Uncle peeping on her because...Chapter 2 creates continuity issues with the prologue, the game overs no longer make sense if it was all a set up.
1.) That would really make him not that much different from her father or brother...
2.) There is no camera to catch him for the blackmail material that her mother told her to get on her Uncle...
Her walking around and slowly seducing her Uncle was a means to groom her Uncle for the "Big Show" that her mother told her to do and get dirt on her Uncle to put him under her mother's thumb (or what Janice thinks will happen)... if her Uncle avoids the bait, Claire takes it onto herself to get the dirt a different way... by molesting her Uncle and making it impossible for him to deny her and, thus, get the proof her mother told her to get...
Claire didn't want to do what she did, deep down... but there is also a part of her that did enjoy it because it was a person that she cares about and loves and someone that cares about and loves her... and having been groomed and molested at an early, Claire believes that sex is how one shows love... a reinforced notion that is repeated hammered into her by her mother and also brother.
Also, had Claire refused, her mother would've made things miserable for her daughter, probably by way of her brother... or worse...
Those who play our game have to understand that there is more at work than simple pictures and clever (overused tropes)... the experience is also, hopefully, cerebral as well and makes people think or reflect on previous situations and draw a line between the two... additionally, this uses my ability that I've practiced since a child and watching people, seeing how they act, react, their beliefs, the things that make them 'tick' to be the writer that I am... and I use that in ALL my writing, even a 'porn' game, and I will tell you right now... the reality of the way Claire is and believes and REAL... it is based on someone that I know and have seen first hand the "Showing Love is How You Make It" structured belief from an individual that was molested at a very early age... and how fucked up her life and any relationship she has ever tried to have as a result of that experience.
Continuity error... no... too damn real, yeah... but no continuity error.
