Rydia's double will just be a copy of Rydia whose final goal is to make other people feel miserable and sad. She will be smiling most of the time and appear friendly like her original self most of the time but do her best to enable people's worst behaviours/humiliate them/make them feel miserable. Sadly Rydia lacks big secrets worth sharing but who says she can't make up things about the real one?

Don't trust that big smile, she only wants to hurt you!
