au where mulder and scully were childhood best friends before samantha disappeared (heavily inspired by an edit i saw)
mostly hung out after school, would hide away in the library or the school basement to eat lunch together
mulder would explain the entirety of star trek to scully while she’d be doing her homework
would go into the woods to play explorer or cops
Bill jr would definitely tease scully about her friendship with mulder and do the whole „dana and fox sitting in a tree“ routine, and scully would be mortified
they definitely gossip about their classmates together or give each other judging looks during class when someone says something stupid
mulder is accused of having cooties bi-weekly by his very geeky friends who get a heart attack whenever scully hangs out with them and mulder
definitely found some fragments of a UFO in the woods one day and argued over what it was while carrying it home
