Do you have any headcanons for what he'd bee like as a teen?
Hmm he’d be the gentler, more mental-oriented one. I say that because Charlie took up boxing and mechanics. So Sammy would be.. more interested in history and literature throughout the times. He’s good in class and he and his sister get along well!
He’s a bit of a nerd, but not so much he doesn’t have friends. More like- his friends just aren’t the “cool” kids, you know? He doesn’t get animatronics as much as his dad and sister (working-wise), so he’s delighted Will is more the encouraging sideliner too!
He likes RPG video games and picks out the storyline. He then regurgitates it to anyone who’s willing to listen.
*As a twin I naturally do this with twins, making one different than the other fairly intensely.,,..,. But I hope this makes you happy regardless!
