Two scenes are clipped from the upcoming episode of "The Vampire Diaries". The first one gives the spotlight to a conversation between Anna and Damon about the robbery in blood bank while the second one is a small talk between Stefan and Damon about the former's craving for human blood.
According to the official synopsis from The CW, Damon discovers that Stefan is hiding a dangerous secret that could impact everyone in town. The preview for the particular episode also showed a wild Stefan biting to a woman's neck. However, Stefan tells his brother that he's "clean".
