Hi, you can look at the walkthrough here to get this ending: https://arghbulous.itch.io/the-muzeum/devlog/1069574/walkthrough-for-all-endings
Some things to pay attention to:
- answer correctly to the quiz
- get esteem points from the curator (follow section 4 of the walkthrough. The gist is don't pry, be thankful and interested in the exhibition, ask for more infos on things he shows you, show thirst for knowledge)
- flee & grab his hand
- agree on worldviews
- follow ending 8 section for the rest of the choices.
Good luck!
