Elena: Caroline’s dad! Stefan, he was able to resist compulsion. I don’t know how, but he did it. Maybe it’s possible. Stefan: Yeah, yeah. Maybe it’s just mind control, right? Maybe it just takes some focus, a couple decades of training. No big deal.. Elena: Stefan, you can control this. When that buzzer goes off, just… just drink from me.. Stefan: You don’t get it. I can’t stop, Elena! I’m a ripper! A ripper doesn’t stop! I listen to the words that come out of your mouth, and all I hear is the sound of your heart pumping blood through your body. And when that clock ticks down…I’m going to have to feed on you. And you want to know what’s worse? I’m not going to be able to stop..
