And who knows. we have not yet seen the full range of Emma's powers. Her primary is light, just like Regina's primary is Dark. But we have seen Regina use light magic, and Emma was originally trained using Dark Magic techniques. Emma may also have Ice Power that we  have not seen yet, or others.

I'm a little worried for Emma in this episode, though. Between what Ursula revealed about Rumple's plans, Killian revealing that Emma is his Happy Ending (and that he was a Villian), and a scene or 2 in the Promo, it is possible that Emma may at least take a step down the dark path.
