Why did Gothel want the Dark One's Dagger? Why does she need it? She is an immortal tree nymph. She is older than Rumple. She can do magic in the Land Without Magic with little to no effort. So why does she need the Dagger?
I understand Facilier's motivation. He wants power. But Gothel is such an odd person to want the Dagger. Did she like it for Tilly/Alice? Did she want Tilly/Alice to become the Guardian?
