He had been awestruck when he had seen Elena enter the room in that dress. She had been a vision in that dress. "I don't know how you managed to walk in that thing. It looked like weighed twenty pounds." Unfortunately there wasn't much left of the dress from what the bedroom floor looked like. Damon in his impatience had opted to tear some of the material off of Elena.
At Elena's questions, Damon wished he had a drink. "We can't go back to how we were before." He looked at her. "I can't be selfish with you Elena. I have been in the past and I can't do that with you. You're too special to me. I will be whatever it is you want me to be. Your boyfriend or your friend. You're in control here."
Which was unnerving to Damon. He was used to manipulating things to get his way but he couldn't do that to her now.
