The Secret Triwizard Challenge

You cast Protego and try to run in a zigzag motion towards the exit. Unfortunately, this doesn't distract the spider, which runs and hits your shield head on. Your spell isn't strong enough to hold it back. The spider rams into you, knocking you unconscious.
When you wake up, you learn that the monitors on brooms managed to save you (and your rival, who you heard scream earlier) from the spider. You're stuck in the hospital wing until further notice, but the worst pain the knowledge that YOU LOST!
