Yea, that's true. There's a massive difference between the time of the other characters. I guess TTrick realised he needed a way of pleasing more people. Im reality, Ann would be a plaything, she's a girl clearly on her own path of sexual self discovery, the fact she'd already clearly been serving Chris with his "coffee time" would have been a red flag for any boyfriend. Even one open to sharing her. It shows no boundaries, whereas the cinema scene showed she was trying her best to share the experience. It felt like the time she'd spend with Chris was far too secretive. To openly show how comfortable she was with Chris, without any updates to the MC showed me Ann was unable to share with the MC. But then why should she? as I said before, the'd only been on one date. It's because as the MC, you always see it from his perspective.
