In this episode, everyone in Storybrooke joins Mary Margaret and David as they prepare to give their newborn son a coronation, while the time traveling portal that Zelena created before her demise comes to life, and takes Emma and Hook back to the Enchanted Forest before the events of the original curse.
Emma and Hook must find a way to return to Storybrooke, but while attempting to do so, they accidentally interrupt Snow and Charming's first meeting, and they must repair the timeline with Rumplestiltskin's help before it is too late to undo the damage.
In the present day, Emma looks happy and sees Mary Margaret holding her baby boy as she prepares for the upcoming coronation even though they haven't named him yet.
Emma changes the subject and starts thinking why her parents are trying to expand the time they need to name the unnamed baby by using an age-old tradition.
Later on at Granny's, everyone is recalling or retelling stories of how Mary Margaret and David originally met back in the Enchanted Forest and how they kept running into one another and were destined to be together.
When Emma reveals her desire to return to New York City with Henry in an attempt to leave Storybrooke behind, Regina and the others exclaim in protest.
Meanwhile, Regina, David, Belle, Gold, Robin, and Mary Margaret visit the jail to see if Zelena had died around the same time as the portal's opening.
The conversation is cut short when they notice the time-travel orange beam forming and Emma runs towards the barn, where the doors burst open.
Emma discovers that she interfered the past and realizes that the only way to stop this altered timeline is by seeking out the only person capable of correcting this mistake, namely Rumplestiltskin.
The Evil Queen arrives at the palace to ask Midas to search the place just in time for Snow to show up and take the ring.
