Stabbity is a lot like Helga from "Hey Arnold." She had a bad family life. Something about her sister. She takes it out on everyone. Nobody around her really understands her animosity toward Arnold. Helga is one of the bully characters who picks on Arnold the most because she likes him the best. The only way stabbity shows affection is by, well, stabbing everything nearby. I mean, How many IG years did Jonsu spend in D'Hara systematically pissing everyone off?
Then, as Jonsu and D'Hara grew up a bit and got into the dating age, Jonsu, knowing that picking on people wasn't getting her the proper attention or respect she wanted, decided to 180 and date one of those arrogant jock-types from the cross-town rival school in hopes of being chosen as the next prom queen. But her plan got twisted when instead of being jealous, D'Hara just breathed a sigh of relief accompanied with a bit of nervous laughter, wondering "Is it really over?"
It wasn't, of course. Jonsu hated the fact that D'Hara was dating other girls. Jonsu doesn't really date, she...accessorizes. So Jonsu got her new boyfriend accessory to get some of his athlete buddies together to come show those D'Haran's what for. But they were drunk and ended up going home without accomplishing very much. She tried going to church, but so far that hasn't helped her very much either.
Years passed, Jonsu and her Boyfriend got married. He got an athletic scholarship, but made an ass of himself so now most of his new teammates hate him, but can't get rid of him. Meanwhile, Jonsu went back to her boyfriends old highschool where she "works" as a substitute teacher. She now owns several cats.
Meanwhile D'hara decided to date some girl named Vesperi and got Tybaltian syphillus. D'hara goes on to die, cold and alone, their closest friend having been chopped into three pieces by that kid who used to torture animals, Aurvandil and his meth head friend Asylon. :p
These both sound remarkably accurate.
