Il Dottore

He often stays in the laboratory and works without getting any sleep. He lives on coffee. Very abusive, considers the research subject a thing, can be rough. His favorite research subject was the 6th Harbinger, the puppet. He treated him like an object as well, but over time his attitude begins to change..
He also works with the 6th Forerunner, the Balladeer (Scaramuccia), and they conduct experiments together, sometimes on the boy himself. The Balladeer evokes unusual feelings and sensations in the Doctor, which he ignores. However, Dottore finds himself experiencing emotions of concern and longing for the boy. Sometimes, he becomes too gentle around him. Despite this, he continues to ignore these "feelings" and struggles to describe them. But with each passing day and their work together, this bond grows stronger. And only the Scaramucci has this effect on the Doctor. The doctor clearly tolerates the guy's poisonous character, even though he sometimes puts him in his place. The doctor doesn't show his true emotions until the very end, especially tenderness and care, because he considers it a weakness. That's why he hides behind a cold and calculating scientist's mask.
