Her family joins Katerina as she is crowned the Queen of Mystic Falls. Her tragic flaw is being blinded by love.
Katerina is blinded by love as, she meets a young fellow named Damon and requests to marry him at once.
Katerina thought of Damon as her pride and joy. Yet, she was blinded by love to know the whole truth. Damon used her, beat her, and abused her all the time. She never said anything to him about it because he was the only guy that loved her.
Katerina's parents find out what has been going on and decide to take it into their own hands. They ban him from the Kingdom so, she will never have to see him again. Katerina was shaken up by the news and decided she needed to act fast for revenge and for her love to come back.
Katerina sits down and writes a letter to her parents, stating why she did what she did. She needed him in her life, despite all the evil things he had done to her. He was apart of her in some way, she felt as if she couldn't live without him.
Katerina goes up to her room, ties a rope to her bed then, around her neck. In her last few moments she realized what she did was selfish and wrong but, she knew it was already too late. She tried to break free from the rope but, the room became darker, her face became pale, and then next thing you know she's dead.
