Even though it was not yet up to 7 days when prince Hedy and Stefan were meant to revisit Lizet , She was already done with what she was doing and decided to visit them herself.
She had succeeded in making a spell that would be put on king Erikson and queen Ursula to turn them totally away from prince Walter. That was the only thing she could do as she was not able to access anything concerning prince Walter himself. So she can not give out any important information about him. The spell she was able to do can only work or become active and effective on them if they give ears to what she would tell them and do as she instructs them, that why they would be caught in her web else it would never work.
