“We’re going to see the first week of the curse,” co-creator Eddy Kitsis teased at PaleyFest. “We’re going to get more insight into what it was like that first week in 1983, and what it was like for the Evil Queen to win.”

The flashback-heavy episode also welcomes back Jamie Dornan as Sheriff Graham, and he appears to be trying to woo Regina with a white rose. (“There’s a lot of flirtation,” Lana Parrilla told us.) Too bad she’s got her hands full with a mysterious visitor named Kurt Flynn (guest star John Pyper-Ferguson) and his son Owen, who have somehow found their way to what Regina had believed was their “undetectable” town.
