Hey,
This was inspired by a challenge, details are below.
Ron goggled as his best friends walked into the hospital wing at the exact moment that they vanished on the spot. "Wh - but, how did you get over there?"
Hermione rolled her eyes. "Don't be silly, Ron," she replied. "We've been here the entire time."
Ron shook his head. "You can't have. You were right next to my bed first, and then the next moment you're walking into the room. We're not old enough to apparate yet, 'Mione, sides - you can't do that at Hogwarts. Everyone knows that."
Harry sighed. "He's got a point," he said, making his way over to his friend's side. "We're going to tell him about it eventually, so why not now?"
Hermione glanced between the two boys. "All right, fine," she muttered, sitting at the edge of Ron's bed. "You know how I told you I was taking every class I could this year...?"
It was going to be for Hogwarts School Challenge forum's Defense assignment 5 - Blink quote #2
