I'm stuck there as well. By peeking in the vids and images, I guess you need to spy Ava (at night?!) again. There is one vid, where she uses the dildo instead of her hands. I guess that after this key scene, you are actually able to search the drawers in her bedroom. However I didn't manage to peek at her using the dildo.I'm stuck after taking the dildo away. No hints, hospital is gone and nothing new happens during any interactions with her. Going on 6 weeks in-game now.
