Stefan Salvatore: Elena. I would never hurt you. You're safe with me.

Elena Gilbert: All those animal attacks, those people who died?

Stefan Salvatore: No. That was Damon.

Elena Gilbert: Damon?

Stefan Salvatore: Yes. I don't drink human blood. That's not how I choose to survive, but Damon does. I'll explain everything to you, but I beg you, Elena... do not tell anybody.

Elena Gilbert: How can you ask me that?

Stefan Salvatore: Because you knowing this is dangerous for so many reasons. You can hate me, but I need you to trust me.
