I didn't see the scene where she's hypnotized on the chair, I should go chat with her while she's in her room.
Edit: spent quite a bit of time doing every possible interact (deepen, change, grope, masturbate) at every possible timeslot (morning, noon, evening (night excluded because you can't wake her up or do anything sexual with her in her sleep)) and couldn't get the scene, turns out if you talk while she's playing videos games on version 0.02b (not just 0.02) you can get a new interaction.
