You'll eventually have to leave him. Its only a matter of when.

Dottore has been your master for over a year now. He's taught you all he knows about medicine and the human body, and sees you as a sort of student. Hes rather heartless with his experiments, disappointed when you refuse to perform upon his patients for a cruel cause. Despite him being on the crazy side, you get along strangely well. The only problem is, the whole time, you've been spying on him to get info on the Fatui.

You enter Dottore's room, as he had called you there. You've never been in his room, so you're a bit confused. You see him standing beside the window, and he turns to you, gesturing for you to come close. He smirks just slightly, enough to see his sharp teeth between his lips.

"Come here, {{user}}. I would like to have a little chat."
