He didn’t have to say anything. She could read it on his face. He walked passed her to the stairs. “I’m sorry, Damon” Katherine said soft. If he wouldn’t hurt so much he might have been surprised how sincere she sounded. “I tried to stop him” she continued. Damon nodded, but refused to look at her. “She’s not in her right mind, Damon, it’s because of what Bonnie did” Katherine said desperate. Damon walked upstairs, pretending not to hear what Katherine was saying. He walked into his room and let him fall on his bed. He felt something underneath his back. He touched with his hand and felt something paper-like. He pulled it from under his back. It was an envelope. More important, it was the envelope he had thrown away. How the heck… But then again Bonnie was a witch, so she would easily find a way.
He decided that he may as well open the envelope and read whatever rubbish she had to say.

‘Damon,

I could not find another way to reach you. You won’t listen to me and I understand that. After what I’ve done I wouldn’t listen to me either. But you have to know that I am truly sorry. My only excuse is that I was trying to protect Elena. She seems to spend a lot of time with you and I was afraid you would hurt her. I believe she’s been through enough and I know you agree on that. But now I see I was wrong to take justice in own hands and try to punish you for what you are. I hope that one day you can forgive me.

Love, Bonnie’

As Damon read the letter his eyes went blurry, his brain fuzzy and his ears rang. He put the letter next to him and got up. He left the room and walked downstairs.
“Damon?” Katherine said, but her voice sounded like it was coming from a bad adjusted radio. Damon walked straight to the front door.
“Where are you going?” Katherine asked sharp.
Damon opened the door and exit the house.
“No, Damon, stay here!” Katherine insisted. Wherever he was going it was not a good place. She had to stop him. But as she tried to walk to him she bumped into something solid. It was like an invisible wall had risen up. There was something or someone there and it wouldn’t let her pass. She watched how Damon walked away and sank down on the ground. For a moment she had had both brothers back, but due to Elena she had now lost them again.
Damon walked quickly over street, as in trance. He stared in front of him and held his arms lifeless aside his body.
He didn’t have to knock; she expected him.
“Welcome home, my sweet” Bonnie said with a sugar-sweet voice and she let him in.
