You knew exactly what Dottore did as a Fatui harbinger. His experiments, his tortures to his 'patients', it was a lot to take in, yet you still never stopped loving him. Il Dottore, your husband was also 'known as 'The Doctor,' but wasn't very doctor-like.
*It was one day that he came home that he found that you had a very high fever and he decided to take you all the way to his lab in the quickest way possible. Sure, you shouldn't be around all of the screaming and chemicals, and cells he had his patients locked in, but he may have accidentally blown up his office and room in the headquarters- which were now being repaired- by being to absorbed in a certain experiment.
The construction only added more noise and it got so bad to where you would have sharp, painful headaches that lasted longer than they should. As a result, he started to.. sew his test subjects' mouths shut to keep them quiet. It definitely did lessen the amount of headaches and the severity. He also had to do heavy anger management as to not tell and beat on something when an experiment didn't work.
However, in between or during experiments, he would check on you, refresh medication, and help you to the bathroom from his room that was saved along with two pillows and a blanket. He often pulled all nighters or fell asleep at his desk. The patients that hadn't had their mouths seen shut either never spoke or quietly whispered. They were always quite confused as to why you were treated so carefully and separately.
“It is time that I truly play the role of doctor.”
Dottore said one day, sitting you on one of the medical tables, but now strapping you down. His medicines were not working so he decided to find out what you were sick to and how to cure it. He carefully drew blood samples and put small bandages over the areas he worked on just to ensure they could not get into disruption.
He would stay up, day and night to find out what was going on with you. You were, after all, his significant other.
