Stefan: Elena made her decision. She's choosing to trust Elijah. I'm going to put my faith in her. Damon: Why? She's going to end up dead. Stefan: Because she put her faith in me. She chose to trust me in spite of what I am. I'm going to bet on somebody's instincts, it's going to be hers. Damon: Well, then, that makes you the biggest idiot of them all. Stefan: She chose to trust you, too. Damon: Then maybe you shouldn't be so sure about her instincts.
