there's quite a few people who claim that the polybros personality is interchangable, but there is a slight difference
the "duh" answer is that polyurethane is more violent, but after rewatching some scenes, i noticed polyester is slightly more polite and gives more compliments / motivation to polyurethane + is more positive in general, meanwhile urethane tends to put the anarchy and demon sisters down more often and is more prone to action against them
some examples
"that's like, so illegal" and "so, like, we're lowk going to report this to the higher ups"
"lowk feels like we're about to kick it into high gear" vs "well iykyk right? and i know salty losers when i see them"
"looks like we caught something important to the chopped huzz" and "but like, lowk it kind of looks like trash"
"sounds like someone's disrespecting his highness" and "hell no, we're not taking that shit without some serious clapback"
"wuhuh???" and "a human???"
kicking away garter's offerings + "permission to chase them" + his clear disgust at the demon sisters and famously: "my father? 🥺" vs "f- father, permission to annihilate?"
especially during the casino trip, we get to see polyester's softer side (bonding with brief, he fw the humans)
it's a nice touch cuz it distinguishes their vibes of older and younger brother
but also, he doesn't always agree, which indicates that polyurethane is more rebellious (ex. kneesocks always agrees with everything that scanty says, which is obviously making fun of western tropes like the rest of the series)
i don't think polyester cares as much about status as much as polyurethane does but this is definitely because of ramie's influence... i don't think they'd be like this otherwise. outside of being an angel (field trip) they're pretty chill. + ramie raised them as tools, not as sons. it'll take them a while to break out of the mentalities that ramie imposed on them
so my prediction for next season (whenever that is...) is that polyurethane will take more time to come around
also i noticed that polyurethane is driving instead in the credits scene (?) when every time before, polyester was driving. maybe that means something
ik this show is not that deep in general but i thought it was interesting!!
