Oh pog you're taking requests... How about Miles helping Sebastian study or honestly anything with Sebastian 👀
Funny faces aside though, i have a headcanon that Sebastian has a lot of brain stuff he struggles with that went for years undiagnosed because his father did his best to keep up the illusion that he could never be bad at anything while simultaneously....beating down his self esteem 😔 i think he has dyscalcula (and autism) that he finds out about later and goes “ah, so that’s why none of this makes sense....fuck!”
(Also huge shoutout to my friend @my-wandering-vagrant for helping me out with the dialogue because it’s been 48747472882384 years since i did anything math-related!!!)
