At first, Dawn didn't know what to feel about the whole concept of the first life. She wanted to hate Zenith. She did hate him for what he had done.
However, all of her anger actually directed to her father. For what he had put her through for years. While her anger toward Zenith was irrelevant, because it was something that he didn't do in this life, her anger toward her father was very relevant, because it happened in both lives.
Dawn didn't want to see Zenith because she was not sure how to feel about him, but the moment she saw him and remembered all of his warnings and his efforts to make things right for them, she relented.
Dawn realized that she was not that angry to him. She was only sad because all of their problem stemmed from how he didn't believe her and choose to blindly believe people around him.
