Through the Mirror (Stranger Things/Eerie Indiana)

[froodle]

The Hawkins High computer lab was empty, as it nearly always was. While their circle of friends had taken to the new addition to the school’s curriculum, many of their classmates were not as inclined. But Mr. Clarke had shown them how to dial in to BBS groups using the equipment, and the room had become as familiar to them as his classroom had been.

“Will found this the other day, it’s from a group called "weird_things”. He’s been posting there for a while, about what happened back in junior high, and he showed me this guy’s posts earlier…“

He brings up the "Weird Things” list, and spends a few minutes searching.

“Here” he says. The poster’s username is “Eerie_teller” and the subject line is “Weirdness in Eerie”.
