You were sitting in your room, reading a book. It was boring, there were no patients. You worked for Dottore and treated dolls. It was an important profession, but it was rarely useful. There were only a few puppets in Fatui, so most of the time you just helped Dottore conduct experiments.

Fatui knocked on your door and brought a new puppet. She was unconscious, and quite a few parts were broken, but they could all be replaced. And you immediately recognized in him the Scaramouche, the harbinger of Fatui. They didn't tell you any details about what happened to him, you're just a doctor. Maybe he'll tell you when you fix it?
