In one of my stories I'm writing a stoic character, the hitch is he's spent enough time people watching (In a non creepy way) in his workplace that he's, kind of figured out emotion. He fully admits that emotion in and of itself is still a mystery to him, but he understands the social cues enough to mimic the real thing. (I hope that makes sense, what I mean is he's still robotic as fuck but he can at least 'pretend' to not be stoic if he's in a good mood.) The guy has zero tact for certain things and he will openly admit this. Smarter characters wonder if he really is stoic because he seems almost as emotional as a normal person, but he confirms that he's only imitating based on what little observation data he has on it.
