Vampire Diaries season 4 Damon to majorly battle new vampire hunter in ep 13. Recently, Kristin over at E! Online ,revealed a new Vampire Diaries season 4 spoiler tease for episode 13 that could find Damon in another heated battle against a new vampire hunter,named Vaughn,that will be arriving in Mystic Falls. From the sounds of it,he won't be there to make nice,and will have his eyes particularly set on the Salvatore brothers. Vaughn is played by former Twilight Saga star Charlie Bewley,so he should feel right at home on the Vd set. Kristin stated in her spoiler chat session, "Bewley will debut as Vaughn in the CW series' 13th episode and let's just say he's got his sights set on the Salvatore brothers. You see, he's a hunter, one of The Five, to be exact, and like Connor, he's pretty damn good at his job.
