Down the Rabbit Hole

S4, E14: On the island, Damon has an ugly run-in with a Hunter named Vaughn (recurring guest star Charlie Bewley – The Twilight Saga), and realizes he is one of the Five. Stefan confesses his true feelings about the possibility of becoming human again to Elena. When a stunning new piece of information about the cure is suddenly revealed, it changes the stakes for everyone. Jeremy helps Bonnie recognize what is real and what is an illusion, and Shane (recurring guest star David Alpay) is comforted by a woman from his past, Caitlin (guest star Camille Guaty – Prison Break). Back in Mystic Falls, Caroline and Tyler find that their attempt to translate the code on the Hunter’s Sword is futile without help from Klaus, who has his own reasons for solving the puzzle.
