These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way.

YMMV: Harry Potter and The Mysterious Curse of the Girl-Who-Lived
"There she is, folks," the voice of Lee Jordan echoed over the field. "The girl was in the Hospital Wing this very morning, and now she's flying like nothing's wrong. I don't care what anyone says, Gryffindor girls are the best."
"Jordan!" McGonagall snapped, albeit not that harshly. "Keep your entirely accurate but irrelevant comments out of the game."
Harry's confrontation with Quirrell and the Mirror of Esired plays out a little differently, as Harry is actually halfway expecting Quirrell in this story (since Snape is a lot more civil to "Harriet" than he is to "Harry," he is not the obvious villain Quirrell had hoped), he is a lot more snarky when describing what he sees in the Mirror:
"It's marvelous!" he enthused. "I'm there with Dumbledore and my parents and all my friends, and I'm holding the House Cup high! We've won! And oh, look, there in the corner is you, getting your bollocks kicked by a team of Muggles." He wiped a fake tear from his eye. "I don't know what this Mirror is, but I think I'd like to move it to my room."
