Hi there! Sweetpea’s about four inches taller, but they weigh about the same because Honey is enormously, ridiculously jacked. Like, Grant and Stepanya are more yer lovely MCU-style Rogerses, but Honey is a hulking comics-style Steve. The serum didn’t initially make him that big: he has an incredibly strict nutrition and workout routine that he uses to make himself as huge and terrifying-looking as possible, because I AM THE ONE WHO KNOCKS is kind of, like, his aesthetic.
However, in a theoretical future where he and Sweetpea have nice peaceful lives together, he slowly drops about fifty pounds of muscle from easing off on the grim bodybuilding diet and skipping workouts in favor of staying in bed and snuggling, so he gets to be Sweetpea’s tiny little 6′2″ 200 pound guy again.
Sweatpea, on the other hand, gets more into his grooming/workout/self-care shit the happier he is – he was a successful amateur bodybuilder in the ‘30s and really enjoyed the sport – so once they achieve Peak Domestic Sweetpea spends a ton of time fussing with his hair and terrifying the shit out of crossfit bros (on one particularly Good Brain Day he manages to ask an especially annoying bro whether or not living off of the flesh of your victims counts as paleo), and Honey spends a lot of time futzing around in his pottery studio and eating noodles in bed and cooing over how big Sweetpea’s muscles are, wow, so big and strong, so sexy, while Sweetpea preens.
