Viktor Krum wants to try and prove that not all people from Durmstrang are bad. He wants to show that what happened in the maze was a mistake. He wants to fight for the good now that evil has touched his life personally. So he agrees to go undercover as a spy in Durmstrang looking for kids who might be being recruited by Voldemort. And of course, he gets wound up with the one girl who just might be his downfall. (thanks to trixytonks for the banner!!)
