When I finally read about Snape and Lily’s story on the Deathly Hallows, it beckoned thoughts of the story I’ve wanted for three particular characters I’ve really liked since the Sorcerer’s Stone. That particular story line (either side of it) did not happen, though.
Side 1: It was that a certain messy-haired Potter boy (Harry) would end up with a really smart muggleborn witch (Hermione) and said Potter boy’s Slytherin nemesis (Draco) would be outrageously jealous over it, he unwittingly becomes a Death Eater.
Side 2: That the Slytherin boy would end up with the smart muggleborn witch, and Potter boy would end up with someone else.
At least Side 1 happened in James and Lily’s story. And so now, we have Harry.
