'OUAT' Rewinds To Storybrooke: Day One

Sunday's episode of Once Upon A Time promises to deliver on a few fronts.
Not only does the episode feature the return of dearly departed Sheriff Graham, but its flashback structure provides a unique insight into the town's formative hours as Welcome To Storybrooke shines a spotlight on the day after Regina cast the curse.
As you can see from this sneak peek clip, she spends much of the episode checking to see her curse has stuck -- going as far as to dangle a comatose David in front of Mary Margaret.
How will reframing Storybrooke's cursed days change our perspective on the townsfolk now? Tune in to ABC's Once Upon A Time this Sunday at 8 p.m. to find out!
