Happy Endings means end of show, so I hope not!
I think S2 was more about what happens when you bring magic to our world.
I think S3 will be more about redemption for Regina, Rumple and Hook.
Maybe they end the Snow White saga, and start something new in Season 3 perhaps with Aurora’s family.
Season 2 from ABC
Now the fairy tale characters must contend with magic in their quest to find a way home, as new fairy tale characters are revealed, old acquaintances are revisited, and some we had come to believe could be trusted will turn against their own kind.
