Will didn't mean any harm, no, really he didn't. It's just that as a Herondale, he has the right to remain vigilant at all times. So Will may or may not have reacted to the cold hand that had been placed on his shoulder as he attempted to drain his fourth glass of firewhiskey. Will may or may not dug his teeth into said hand, hard. Will may or may not be sat in Dumbledore's office, after being flushed out of the room by a very angry Proffessor Slughorn... Details, details.
Dumbledore glanced down over his half-moon spectacles at the boy stood in front of him. Eye twinkling slightly, the wizard watched as the black-haired shadowhunte-r stared at his shoes as he scuffed them on the floor.
"You bit Proffessor Slughorn's guest, at a party no less?"
Will let out a small, affirmitive grunt.
Humour sparkling in his eyes, the Proffessor asked a simple "Why?"
The Herondale muttered a few sentences, and continued staring at the floor.
"Excuse me."
"Natural reflex. Vampire. Bite."
I always seem to forget that when a vampire bites William Herondale, Will Herondale bites back.
No, 'bite me' is not a suggestive term, thank you very much you dirty-minded heathens. :)))
