In the play, Stefan and Damon compete to be the people who send Catherine to hell. Damon took control of human Stefan and told him to leave. Stefan left with vervain. He took Elena's blood and injected Damon, and Damon became human again. When Bonnie sent the fire of hell back to hell, Stefan and Catherine died together, and Catherine went offline.
Catherine's role setting
Catherine used to be a lucky woman. She was loved by many people, but fate gave her the cruelest arrangement. Everyone who loved her was missed by her.
Catherine's famous saying: "You are better off dead than me", and her logic is correct. Live first, then talk about freedom and love. Her wishful thinking has never been understood by the two most important people. 145 years later, Stefan and Damon thought Catherine was the devil queen and Elena was Snow White who needed protection.
Catherine can lie and hurt others by any means to survive. Even I believe those lies are true. She was the only one in her life. She has no family, no friends and no one cares about her. All the problems she encountered were solved by herself. There is a scene in the play in which she steals Stefan's money, which makes people feel ridiculous and sad.
