ok so here's the thing about jercy. they're like an onion, they have layers
they are totally boyfriends that call each other dude and bro all the fucking time, they tease each other and joke around, they get into dumb competitions with each other and their banter is top notch
but they're also. all over each other. and not like in a making out in front of everyone kind of way but like you can't tell me jason isn't touch-starved and i just know that his sweet, empathetic, emotionally intelligent percy is going to pick up on that. so Percy is always touching Jason, an arm over his shoulder or resting his hand on the small of his back or holding hands while they patrol with their swords in their dominant hands. jason probably doesn't realize how badly he needs it until he gets it and then he doesn't know how to ask for it but percy delivers anyways. eventually jason works his way up to using his words and even initiating the contact he craves all by himself
bottom line they are soft for each other, as leaders of their camps it's hard for them to let their guard down but with each other they can because they know the other just gets it and they feel safe. you don't think jason absolutely breaks down crying on percy's chest after meeting sally and comparing it to his own mother, while percy holds him through it and reassures him that sally is his family too? you don't think jason will stay up all night holding percy when the nightmares get to be too much? i think these two are able to open up much more to each other than anyone else. they're both the big spoon, they're both the little spoon, they each need it sometimes ok
but just because they're soft and in love does not mean they don't go hard on each other in training, they fight in the arena without holding back. they're still super competitive with one another whether it's sword fighting, demigod abilities, or dumb stuff (including but not limited to flirting and making the other blush). they know the other can take it
but oh my gods if one of them gets hurt? they are so fucking protective. between percy 'loyalty is my fatal flaw' jackson and jason 'raised by wolves' grace they would do anything, go absolutely feral, to keep the the other safe from any threat, real or perceived, because they're so precious to one another. these traits probably also lead into some possessiveness but like they're into it and i promise it's not in a toxic way it's just very low-key they know they don't like "own" each other alright
so like yeah they can be pushing each other around bro-ing out almost looking like they're just friends, or you can question how they can look ready to kill each other when they spar, but you gotta look for the subtle things. look in their eyes, they can't keep the absolute love and adoration out of their eyes. and remember, as touchy as they are when they're relaxing around camp, you will never see what they're like when it's just themselves (hint it's a complete mashup of bro shit and soft love and passion), and if you try getting too close to either boyfriend they will both instantly shut you down
