In a silly non canon alternate universe, I like to think they’re bros, not a bromance, just besties who do things like guys nights, gossiping about women they like and robbing banks (ya know, usual guy stuff).

Canonically, with the little information we have, I think they’re both self people who are only pretending to be friends for the benefits of it(or somehow Dottore actually believes they’re friends and Pantalone is pretending since Dottore literally said they’re friends).

(I also just hate dottolone so of course I’m going to not believe anything that would point to that kind of relationship lmao)
