John was into computer coding even though he sucked at it, liked magic tricks, and other actors that were not Nic Cage. (As for his ‘true sexuality’, no idea what’s going on there. Hussie stated that Homestuck would reach a gay singularity, but John has canonically stated he is not gay. Idk.)
Rose was messy as Hell. She wrote wizard fanfiction. She knitted. She was not always rational.
Kanaya was not always prim and proper. She grew jealous of Vriska’s other relationships, and cut her off with no explanation, which did not help her any- considering she was her moirail, and was supposed to keep her in line. She thought Rose was a troll at first, when she only knew her as tentacleTherapist.
Roxy could hack and code, liked science, and could fluently read morse code.
Vriska was a pretty big history geek sometimes. She roleplayed as her ancestor, and tried to manipulate everybody into reenacting history. Her bad relationships were, at times, the fault of others.
Tavros raised a goddamn army, no mind control needed. Even though he killed Jade’s Grandpa, he also saved her life in doing so. He tried roleplaying with Nepeta. He was friends with Gamzee, but only had one conversation with him that implied Gamzee had feelings for him in the slightest.
Terezi and Nepeta were good friends, and roleplayed together. Nepeta was okay with Karkat not reciprocating. She had a healthy moiraillegiance, not an abusive one. She wasn’t some delicate flower, she hunted and killed animals to eat. She tried roleplaying with Vriska.
Equius never abused or controlled Nepeta. He did not want her FLARPing with Vriska because she lost an arm, Tavros was paralysed, and Aradia died. It isn’t surprising why he didn’t want her to FLARP with them.
Eridan has not once said ‘wweh’ or ‘nyeh’ in canon. He only hit on people who he genuinely thought were into him. The pressure for him to find a matesprit was probably incredibly high considering his blood caste, so his actions were slightly understandable in the romantic sense. He used to be on good terms with Karkat.
‘Fuckass’ was not the only swear Karkat ever used, Jesus. He also liked coding, but sucked at it. He was on good terms with Eridan before the drama started, being able to seemingly effortlessly calm him down. He talked with him in a very casual manner.
Jake had horrible memories of Jane. She got mad at him for forgetting her birthday, she became a trickster and tried to force him to marry her, and yet he still ran in front of a sword to save her. Plus, if you haven’t noticed, the boy is actually really heckin’ small.
Dave, in canon, said ‘y’all’. He was an amateur photographer. He liked collecting preserved dead things. He had multiple blogs. He literally had an entire SBaHJ arc dedicated to nachos. He grew a hatred of the sound of metal due to the strifes with his brother. (I will defend this poor boy to my grave, fight me)
Terezi was not just some girl for Dave and Karkat to fight over. She was immensely important, playing a huge part in the comic (RETCON AND GAME-OVER TIMELINE). She was an aspiring legislacerator. (I spell that right?) She literally killed John once.
No longer eating sopor isn’t the only reason Gamzee snapped, Lil Cal and the ICP video (blasphemy) were part of the reason too.
Feferi wasn’t perfect and innocent, but at least she told Eridan she was breaking up with him, unlike Kanaya with Vriska. Her race depended on her feeding her lusus. She was an heiress, greatly important, again : not a character just there for romance.
