The two-hour finale for OUAT will be split into two segments. The first of which titled "Snow Drifts" will deal with Mary Margaret (Ginnifer Goodwin) and David (Josh Dallas) celebrating their newborn son while Emma and Hook are sucked into Zelena's time traveling portal. The second half, "There's No Place Like Home," will follow the savior and Hook back in time to the Enchanted Forest where they must not do anything to change the past and alter their future.

But of course they find a way to do just that! ABC released two sneak peek clips showing Emma and Hook back in the Enchanted Forest together. The first the pair crash a party hosted by King Midas and must improvise and not reveal who they really are. In the second clip we see the two asking Rumplestiltskin for his help and reveals they may have already altered the timeline. Check out both clips below along with the promo trailer.
