She needed someone that has not accepted magic as part of herself or have not embrace it yet. That is why she is taunting Elsa about her fear, until she embraced it, and Emma until she was able to control it thanks to Elsa. She needed that to be fulfilled so that she can use her ribbons and bond them all together so that she can harness both of Elsa and Emma's power and use it to cast the shattering sight spell. As far as we know, she wants everyone in storybrooke to turn against each other and only have Elsa and Emma as her family.
