It may be worth noting that, for all the hate Alison gets for her actions this Chapter, Holly of all people can potentially pull very much the same shit in this chapter as well -- Lena and Ian can be a couple, but Holly will still throw herself at Lena while paying her a visit, and doesn't even ask, but goes straight for a kiss. And she can't claim she's drunk, either. For many people the only reason things don't escalate to sex right there and then is because the game doesn't give you any input in this regard.I had a playthrough where Ian and Lena were in a committed relationship with each other. If Ian and Alison and haven't fucked by chapter 11, she invites him back to her place (invitation can be refused) and basically tries to seduce Ian and get him to cheat on Lena, knowing full well that he's been on the receiving end knows what shitty feeling that is. Idgaf if Alison was drunk when she asked that.
So, yeah. At this rate the only person in the entire game who seems to understand and observe consent and boundaries is Virgin Ivy.
