I honestly wanna see more of Secret Agent being undercover with, y'know, a cover identity...
Yes, absolutely write them how you want, but I just feel like it'd be more interesting to see how others would explore how Agent goes about whatever mission they have, especially if they're working against Animal Corp.
Make them work as a nurse, a doctor, a security guard, or literally anything, because I feel like them being called and known as a Secret Agent or Agent defeats the purpose of them being, well, a Secret Agent.
A Not-So-Secret Agent in my sibling's own words.
Rather than making them be extremely serious and distant all the time, make them pretend to be the sweetest person that anyone who they talk to gets cavities; make them get into chaotic side quests with some of the other employees to show how well they've managed to blend in with the hospital staff; make them build personal relationships with certain people because they need to get information from them or keep them quiet depending on what they're here to do. Explore what the job of a secret agent entails for Agent.
Again, I'm not trying to dictate how anyone writes a character with no canon lore; I just wanted to give my suggestion, and fully acknowledge this is just my personal opinion and taste.
