Stefan is still locked up because he feels guilty for what he did.(The human blood is out of his system)He wants to die, he will no drink and he took his ring off. During the episode, more of there past is reveled. There father shot them both on purpose because he saw them trying to help Cathrine. Stefan didn't know that when he went to say goodbye to his father. His father tried to kill him but Stefan was stronger and hurt him. He was bleeding, Stefan was in the middle of transitioning(all he needed was blood)he drank his fathers blood. Damon didn't drink yet, he didn't want to, without Cathrine he wanted to die. Stefan came to him with a person and told Damon to drink, Stefan bit the persons neck and made Damon drink.
Damon reveled the truth of why he hates Stefan: He said it was only suppose to be him, Cathrine should have only turned him not Stefan.
