HALQUIUS. i love halquius forever. in canon its really interesting given the fact that they shared a sprite body, hypothetical future where they exist as themselves the sprite would have to seperate (i dont know if thats even possible but for the sake of this scenario it is) and that would frankly be a traumatic experience. arquius existed in this constant state of exhilaration, especially on hals side what with the euphoria of finally Having A Body (+some sort of gender euphoria given the degree that arquius is comically hypermasculine and i think masculinity is something somewhat prominent in dirks character (furthuring my transmasc dirk agenda) which is transformed into something different but still fundementally there in hals character, BUT THATS A WHOLE OTHER CONVERSATION) and then to all of a sudden have that ripped away. and nobody else in the world knows that feeling but hal and equius which would bring them together but in such a terrible way... as much as i enjoy flushed halquius, realistically i think they would be pitch. they would remember how they were as a sprite and simultaneously miss it and regret it and also blame eachother over all those feelings and at the same time they Understand eachother like nobody else could and they drive eachother insane and its just a mess !!!

theres also something about them making hal a body together. hal with his technical knowledge overseeing it and drawing most of the blueprints and equius with his previous experience and prowess with robots actually building the thing. in the hypothetical post-canon halquius timeline this would be before they made their kismesissitude official so theyre just kind of pitch flirting over the course of multiple months while the body is being built which is kind of funny to me... but also when its done. regaining that euphoria of having a body even just for a little while, i dont think hal could deny that he is really grateful for equius's help on the body because it wouldnt be possible without him. he wouldnt vocalize it but something flushed in there too??? who knows

ANYWAY all that does kind of hinge on the whole they were a sprite but separated thing and while i love that concept i think at a base level, without that, i do just enjoy their dynamic. theyre both kind of anomalous freaks who arent taken very seriously/disliked by most others and they both have self-esteem issues, equius thinking quite poorly of himself and hal thinking highly of himself to an exaggerated degree, maybe ironically to cover up an actual sense of self hatred that he inherited from dirk. even just hal swearing a lot and equius hating swearing, low hanging pitch material but alternatively very cute flushed scenario where hal doesnt swear around eq because he knows he dislikes it, it would take a whilee to get used to but its the effort that counts <3 also kind of a reach but equius gravitating towards heart players with hal and nepeta :)

AND MENTIONING NEPETA i do have to talk about her because you cant talk about equius without talking about nepeta. honestly i think she would just be happy equius managed to fill another one of his quadrants LMAO hes such a loser he has no bitches </3 i think hal and nepeta would get along well, they would like. gossip about their friends over tea. love that for them

there is this one fic with them that i really really love, theyre BARELY in it and its mostly just hal + you have to read another veryyy long fic to understand it but it is one of my favorite interpretations/versions of them everr and ill take what i can get :v its called The Future Soon by Unda on ao3 and the longer fic is called M.C. Escher that's my favorite MC (HIGHLY recommend both unda is such a good writer)

there is a lot more i could say about them but i dont think it belongs here and this reply is already long enough lmao,, kind of even more insane about them after writing all that god i love them
