I've always thought the Ann corruption path is a bit odd.
Sweet, innocent, intelligent girl who gets a bit of dick and goes completely off the rails in a relatively short time (it's not clear how long, but maybe a week or two)...Huh?
OK, it's an AVN, so things move fast and all, but that's going from 0-100 in corruption VERY fast. In reality that's only likely to happen if there were serious outside events pushing her, like some major trauma. To be honest, even her 'innocent' route is a bit quick (but not unrealistically so).
Personally, I think a lot of the corruption path should have been given to Alex....Her newfound insta fame (which she described as like an addiction) being that extra push she needed along the road to corruption (not trauma per se, but...), and a career in acting being less of a radical change from her 'influencer' career. It'd also balance out the story between the girls better.
