Keep your friends close and your enemies closer? This adage is anything but ideal, but given the grim circumstances in Mystic Falls, our favorite residents are left with no alternative. Despite being immortal adversaries, Stefan and Klaus will be teaming up in the fifth episode of The Vampire Diaries Season 4. True, they don’t exactly get along and Klaus has proven to be a rather untrustworthy chap. However, with a vicious new hunter named Connor terrorizing both supernatural beings and humans, the two former pals have no choice but to rush in and try to save the day. Check out what happens in the official synopsis for “The Killer” below:
THE HUNTER’S MARK — Stefan (Paul Wesley) and Klaus (Joseph Morgan) form an uneasy alliance to try and contain the danger that Connor (guest star Todd Williams) has unleashed on the town. When Connor takes Jeremy (Steven R. McQueen), Matt (Zach Roerig) and April (guest star Grace Phipps) hostage at the Grill, Stefan and Damon (Ian Somerhalder) have a serious disagreement about the best course of action, and Elena (Nina Dobrev) is again caught between the two brothers. The situation quickly turns violent when Klaus sends one of his hybrids, Dean (guest star Blake Hood, “The Young and the Restless”) to stand up to Connor. Caroline (Candice Accola) is surprised to find Hayley (guest star Phoebe Tonkin) at the Lockwood mansion. Meanwhile, Professor Shane (guest star David Alpay) works with Bonnie (Kat Graham) to help her get past her fear and guilt.
The episode was written by Michael Narducci and directed by Chris Grismer.
What are your thoughts on the new hunter? He sounds suspiciously lethal for someone who’s human? Do you think he’s evil or is he simply taking his life mission a tad too seriously?
