Was thinking about @mishafer 's comment about how the Trio have a 'you mess with one of us you mess with all of us' vibe in hs so I combined that with the broke Andrew hc
(Yes, Warren gets very defensive when people insult his twink, I also have some more hcs below)
Warren and Jonathan are one year above Andrew but they still hang out (Andrew got very depressed in his final year of school because it meant he almost never got to see his friends)
They're each-others only real friends. They're acquainted with some people outside of the Trio but barely know them.
Warren likes Jonathan but Andrew is truly the only person he really cares about. Andrew enables all of Warren's negative traits, Warren considers him his one true confidant.
Andrew is neglected by his parents and brother and usually comes into school wearing tattered clothing and worn shoes which are fixed up with patches and duct tape (done by Jonathan)
While all three of them are bullied Andrew is mostly a victim of heckling and jeering while Warren is the victim of physical violence because of his tendency to lash out.
In canon/Season 6 I like to think a lot of the flannels/graphic tees Andrew wears were previously belonged to Warren but he feels like he's grown out of them and loaned them to Andrew instead.
Andrew has a lot of sleepovers at Jonathan and Warren's houses because it means he doesn't have to stay at home.
All three of them are in the science club
There's also a dungeons and dragons club and they're the only three members. Everyone else has been banned.
Jonathan is the only one that had a prom date. One girl asked Andrew out but he turned it down to hang out with Warren as he didn't have a prom date and was spending the night alone at his house :3.
Warren was supposed to be valedictorian but got denied because of an 'incident'
They frequently engage in schemes and antics and everyone hates them! :D
