"Such a connection could effect in this way. It all depends on how strong that connection would be and how hard she might be trying to use such a thing. Connections through the Force are a strange thing, and I dont think anyone knows how deep they go or all that can happen with and through them."

Rognan, also being a twin, had a connection with his sister. Their connection was small and weak. As time went by, and the more they were around eachother, the stronger it became. He could feel his sisters emotions sometimes, even when he is not close to her. So to say that someone might be able to use such a connection to turn someone to one side or the other may not be as far fetched as some would think.
