An uncontrolable Dark One would be a force to be reckoned with, even for the hero who wields Excalibur. Emma's life may even be the price, for making the sword whole again. This way the characters could go to the Underworld to save someone, and be forced to battle Hell on Earth. As Rumple's heart is currently a clean slate, perhaps Rumple-in-Emma's-head may be tempted to take up residence within Gold, even if Emma frees herself of the Darkness.
