It is possible that Rumplestiltskin will become the Dark One again, only this time not bound to the dagger. 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 have to battle Hell on Earth.
