🤬. How often do they swear?
Rarely. Victor understands that his appearance makes him look... uncouth, and as such really plays at being a respectable gentleman. In private, he may let out a swear or two, typically in exclamation - a startling new discovery or an infuriating, unexpected setback is enough to draw out the occasional F-bomb from him.
(It's worth noting that I headcanon Victor as coming from a very low-class background, and has attempted to play up his image of a wealthy, respectable doctor in order to feel comfortable and accepted among his colleagues. It's a point of pride that he has reached the heights that he has, and would rather not sully his image amongst peers. He can't bear the thought of being looked down upon. It's part of the driving force behind his entire ethos - Victor believes he was chosen by Spencer when he was scooped up by Umbrella for their scholarship program. He made it a force of habit to not swear around his colleagues when he first began working for Umbrella out of a fear of being seen as nothing but poor white trash, even when many of them swore like sailors in the lab.)
