Dennis Creevey
Murphy's Law. Heaven bloody forbid Dennis' first encounter be with a student, a conniving Slytherin perhaps. No, it had to be with what Dennis could only assume was a Death Eater. And not some old, decrepit, insane Death Eater who featured in the first war, but a younger, sweaty, mad-eyed sort.
Of course, most of this didn't actually go through young Dennis Creevey's head as he stood before Lestrange. All Dennis could come up with was,
Shite.
Despite the wand leveled at his face, Dennis stood stock-still, hoping an idea of what to do next would come to him. The DA lessons taught him how to use several charms, but not how to predict what a madman might cast at him.
