Gilmore), and Hook (guest star Colin O'Donoghue) try to stop the trigger after Greg (guest star Ethan Embry) and Tamara (guest star Sonequa Martin-Green) activate it under the mine and start erasing the town. Gold (Robert Carlyle) restores Belle’s (Emilie de Ravin) memories and asks her to protect Storybrooke, while Emma and Regina combine magic to stop the destruction.
