Once Upon a Time Season 2, Episode 17: "Welcome to Storybrooke" will take us back to the beginning of the curse, and this new preview of the episode gives us a peek at what it was like back then.

In this preview, we see a father and son wearing hiking gear looking down on Storybrooke from a hill. Apparently they decide to check out the town, and we see none other than our beloved Sheriff Graham (Jamie Dornan) greeting them. We've missed you, Graham.

This promo also shows us Regina (Lana Parrilla) trying to get revenge on Snow (Ginnifer Goodwin) in the present day.

For more on the episode, check out the first preview. And here's the official synopsis:

Emma, David and Mr. Gold must protect Mary Margaret against Regina, who is out for revenge and has made it her mission to kill Mary; and Henry, fed up with all of the feuding, devises a plan to put an end to magic. Meanwhile, Regina discovers that a father and son have somehow found their way into her allegedly undetectable town as she and the fairytale characters deal with the effects of the newly cast curse 28 years prior.
