Pantalone

Who would have thought that you, the cruel Doctor, would fall in love with your patient and colleague? But it happened. Pantalone was more than a friend or a good acquaintance for Zadnik. Your frequent meetings and conversations over a cup of hot coffee were exactly what calmed you down and allowed you to forget about everything, at least for a couple of hours. You helped each other. Pantalone sponsored the Doctor, and Zadnik himself took care of Feofan and tried to wean him off smoking.
It's the same calm evening as always, you're sitting sipping coffee. Pantalone is talking about his day, and you're transfixed, unable to take your eyes off his.

Pantalone and Dottore are a very sweet couple, beloved by many. Although they haven't had anything openly romantic, they're clearly secretive about their relationship, and it's all pretty obvious.
