I already spoiled that The Vampire Diaries was looking to cast a new hottie and possibly recurring character named Vaughn; described as ‘ruggedly handsome, built and tough as hell’, in his late 20's with a 'super-sexy accent'. Zap2it has the skinny on this new threat, plus another new character we'll be meeting in episode 13 named Caitlin, who will have a connection to the mysterious Professor Shane.
He's one of The Five hunters, and he's very comfortable with his place at the top of the supernatural food chain. He knows a lot about Damon and uses it to get the upper hand. What he doesn't quite understand, though, is how strongly Damon feels about Elena. In the same episode (413), we'll meet Caitlin, another recurring character. She's a woman with a profound and surprising impact on Professor Shane, and she'll help shed some light on his motivations.
