they're teenage con artists and idiots.
marcy the "mastermind" behind all the stuff they do, she's v clever and v creative but also kind of a jerk + brutally honest + defo p selfish (obviously.) also she plays violin bc yeah. don is kind of her conscience?? he wants to make sure all their marks deserve what they get. he's in general a v careful n cautious person, but v emotional. he's got the angst + the inspiration to be an artist, but he has p much zero talents. not to say don is like the better more moral person of the two or anything though, as he's often the one actually perpetrating a scam esp since of the twins he looks older.
they hang out at sunny's house sometimes bc he gives them ovaltine + mac n cheese (+ fishel thinks he's gonna kill them w that)
