"I'm not human. And I miss it. I miss it más than anything in the world. That is my secret | Damon Salvatore" when did he say that?

He dicho that in the end of the 12th episode of the segundo season ("The Descent")!
He was sad and found a girl named Jessica so as to tell her his biggest and hidden secrets and thoughts! Then he wanted to bite her, he regretted and he left her but in the end he bit her.
It was such an emotional and sad scene :( I loved Damon even más when I saw it <3

"I'm not human. And I miss it. I miss it más than anything in the world. That is my secret"- Damon Salvatore
This was dicho in season 2, episode 12 towards the very end.
