<P> In Storybrooke, Henry goes to the pawnshop and meets with Gold who attempts to feign ignorance of the Curse . However, Henry goes to the back and uncovers Gold's potions, proving that Gold remembers his past . Gold acknowledges Henry's cleverness, but also refuses to help Henry as his primary concern is finding Belle . Henry decides that he should take on Fiona himself, and Gold heals his injuries and allows him to take the enchanted sword, Hrunting, from the shop . Back in the Enchanted Forest, the Darkness has arrived at the castle, the Evil Queen decides to sacrifice herself and use all of her magic to protect the castle, in order to buy enough time for Regina to restore the bean with her magic, while everyone else gathers together in the courtyard . However, Regina fails to restore the bean in time, and the Darkness bursts into the castle, surrounding them, while slowly closing in . They realize that Henry is their only hope, since Regina can't restore the bean before they are all consumed . When Henry arrives at the Mayor's office with Hrunting, Emma arrives out of nowhere . She tells Henry that while she doesn't remember being who Henry tells her she is, but she does believe that she can be that person with his help . Her renewed belief stops the destruction of the Enchanted Forest just in time to save the others . The Darkness pulls back, revealing that everything in the Enchanted Forest Realm had been consumed, except for a small column of land that the group stands on . At the same time, Gold uses a tracking spell on "Her Handsome Hero" to find Belle, who was hiding from Fiona, and she hides from Gold as well, having been turned into a coward by Fiona's Curse . Gold tells her about Fiona's deception, and vows revenge on Fiona for what she had done to Belle . </P> <P> Fiona stops by the pawn shop to see Gideon, now that Emma has regained her memories, where it turns out that Fiona had reclaimed Gideon's heart with Curse . Then, she uses him to recover her own wand, which she uses to decipher the mysterious writings that Henry had scribbled in the page . Fiona then reads the inscriptions, which details the birth of Light and Darkness, their battle throughout the ages waged via their emissaries, the deaths of the previous Saviors and their enemies at each other's hands, and how the Final Battle will begin after the Emma's birth . After Gideon leaves to find Emma, Gold arrives in the shop, but Fiona fails to trick Gold into thinking that she had only come for her watch . When Gold confronts Fiona about her plans, she tells her son that once the Final Battle is over, the Curse will be lifted and they can be a family again . She also tells Gold that after she destroys all Light Magic, she will have so much power that she will be able to break the Laws of Magic at will, and she will even be able to bring back the dead . She tells him that she can bring back his first - born son, Baelfire, for him . She goes on to say that with her new powers, she will be able to make his family love him as the Dark One, so that he can keep his power . However, Gold knows that is will come with a steep price and tells her that he refuses to pay the price of magic anymore slipping Fiona's wand into his hand . He forces her onto the ground with magic vowing to make her pay for what she did to Belle . Fiona tells Gold that she had deciphered Henry's writing . She learned that Darkness cannot destroy Light since Darkness isn't strong enough . However, Light can destroy Light . She explains she gave Gideon one final command; to kill Emma, and that even if she dies, Gideon will still be forced to carry out her command . Gold decides to test this and kills Fiona with her own wand, breaking the Dark Curse . This causes Snow, David, Regina, Hook, and Zelena to be transported back to Storybrooke from the Enchanted Forest while Emma and the other residents of Storybrooke regain their memories . Soon afterward Belle returns to Gold and comforts him over his actions, while Gideon arrives at the office with his own enchanted sword in hand . As expected, Gideon confronts Emma and is ready to face off against her . </P> <P> Both Gold and Belle set off to search for Gideon's heart . Henry helps Emma escape from Gideon (knocking him out with a fire extinguisher) with Emma placing a protection spell to contain him temporarily . The others realize that Fiona has crafted the perfect trap: If Gideon kills Emma, Light will be destroyed . And if Emma kills Gideon, she will turn dark and Light will still be destroyed . Regina consoles Emma and encourages her to find another way like she always does . Emma attempts to hold off Gideon as Gold finds Gideon's heart . When Gold finds Gideon's heart he is tempted by a manifestation of the Darkness, which takes the form of his Enchanted Forest counterpart, Rumplestiltskin . The Dark One manifestation tells him to let Gideon kill Emma so he can finally have it all: power and love . The manifestation reminds Gold of what Fiona told him, that if Emma dies his Dark Magic will increase exponentially . After it's all over he can spend all the time he wants exploring the world with Belle and / or destroying it . Gold resists temptation and chooses to do the right thing and tries to use Gideon's heart to stop him from killing Emma . However Fiona's spell keeps him from being able to free Gideon and instead Gideon's heart stops beating and dims . The manifestation taunts Gold before disappearing and Gold heads out to Belle who consoles him for trying to do the right thing . Back at the intersection, Emma and Gideon fight with Emma acknowledging her role as the Savior to protect those she loves, protect the innocent and to spread light and hope no matter what the cost . Realizing what she must do, Emma throws down her sword and Gideon apologizes and kills her releasing an enormous blast of light magic, ending the Final Battle and causing Gideon to disappear . </P> <P> As everyone gathers around Emma's body Henry, using true love's kiss, brings her back to life . Gold and Belle discover to their shock that Gideon is once again a baby with his heart restored into his body . Realizing that this is a new start as a family, Belle tells Gold that this is their happy beginning . Snow then sees the "Once Upon a Time" storybook reappear . Henry looks at the final page of the storybook which suddenly writes itself with the words "When both good and evil did the right thing, faith was restored and the final battle was won ." Snow reminds everyone that the story isn't over . The Enchanted Forest, Neverland, Wonderland, Agrabah, Arendelle, the Land of Oz and all the other realms are restored and their residents obtain their happy beginnings, as does everyone in Storybrooke . Emma and Hook patrol as the town Sheriffs, Henry goes to school, Regina returns to her role as Mayor when dwarfs gave her title "queen" without "evil", David farms with a growing Neal, Zelena spends time with baby Robin, Gold and Belle renew their relationship and raise their son together, Snow White becomes a teacher again and Robin Hood propose to the Evil Queen in Regina's restored palace . They all gather together at Granny's to celebrate their lives together . </P>
