do you ever think about the judges for the triwizard tournament trying to figure out who to kidnap for the second task
like they’re all just sitting in dumbledore’s office and karkaroff goes “well word on the street says that krum has a crush on that granger girl”
"damn," says dumbledore, "I wanted harry to rescue her. well, what about the delightful miss chang?"
"no," says bagman, "we’ve got her down for diggory"
"stop sinking my ships," says dumbledore
It was just their dates from the Yule Ball. Ron and Harry basically ditched their dates and hung out with each other so that’s why Harry had to rescue Ron.
