After Caroline saves Stefan and Damon from her mother, Damon drinks the dead deputy's blood to regain his strength. However, in 162 Candles (Season 1 Episode 8), Damon gave Sheriff Forbes vervain, and she said that she was going to give it to all of her deputies. See more »


When Caroline is sitting down in the dungeon on the Lockwood Estate and has blood on her mouth, the blood changes its consistency. See more »

Damon Salvatore: I heard. And you?
Elena Gilbert: I'm going home.

Disclosing Secrets
11 September 2013 | by (Rio de Janeiro, Brazil) – See all my reviews

Mason discloses to Tyler how he triggered the Lockwood family curse and turned into a werewolf when he accidentally killed his friend Jimmy in Florida. Meanwhile Stefan and Elena decide to simulate a fight to lure Katherine. Stefan, Damon and Mason go to a picnic and Mason tells to Liz that Stefan and Damon are vampires. Then Mason goes to the woods and Stefan and Damon confront him, but the Salvatore brothers are hit by Liz and two deputies and Liz injects them with verbena. Tyler discloses the secret of his family to Jeremy and he decides to give the moonstone to Mason. Caroline is forced to expose herself to her mother to save Stefan and Damon. Mason brings the stone to a car parked in a dark area and delivers it to Katherine, who had plotted the attack of Jimmy.

"Kill or Be Killed" is an engaging episode of "The Vampire Diaries" where secrets are disclosed: Mason to Tyler about the Lockwood family curse; Mason to Liz about who the Salvatore brothers really are; Tyler to Jeremy about the curse of his family; and Caroline to Liz about what she has become. However the secret of the moonstone is still a mystery to be revealed on the next episodes. My vote is eight.
