Comic Book Resources. “After the screening Kitsis and Horowitz briefly discussed the show with the audience, revealing Once Upon a Time will include many Easter eggs from Lost. They specifically cited Emma Swan as being named after the island's Swan Station, the town clock being stuck at 8:15 (an allusion to Flight 815), and a character's house number being 108 (the sum of the six recurring numbers from Lost).”

They told me they thought it was a cool name and they were moved by the idea of The Ugly Duckling story, so it appeared to fit.”

For those who may have forgotten, ONCE show creators Edward Kitsis and Adam Horowitz were two of the writers behind Lost and they always look for fun ways to shout out to it. For instance, when Ruby comes to visit Belle in the hospital, Belle is watching Exposé, a fictional TV show from Lost, which also happened to be Hurley's favorite. Now that's he's moved into Storybrooke, I'll bet Anton will love catching up with it. And if you listen closely, the announcer on the TV just before Exposé returns from a commercial is none other than one of Lost's creators, Damon Lindelof, reprising his vocal cameo of Bill Godwin. Also if you're paying attention during the airport scenes, you'll notice that the flight Emma, Henry and Mr. Gold are on to New York is Ajira Airlines Flight 53. Ajira was the airline several Lost characters used to return to the mysterious island.”

That's yet another reference to Oceanic Flight 815, the fictional airliner that crashed during the pilot episode of Lost.”
