If she can only show up through the summoning, then that gives us a new villain in Storybrooke because someone had to summon the Black Fairy for her to attack Blue. So she probably can travel realms on her own... probably excluding anywhere that doesn't have magic, like the WRabbit and Jefferson's hat.

I wonder if they'll actually make her a sympathetic villain. She could just have legitimately given Rumple up for power.
