Production Development Executive producers Adam Horowitz and Edward Kitsis announced that they were ending the half - season arc structure that was seen in seasons three through five, with Horowitz saying, `` We 're also planning a 22 - episode story as opposed to breaking it up into two halves this year. It has been really exciting and fun. '' Kitsis added : `` We are changing around what we 're doing this year and going back to that season 1 mentality of small town stories and smaller arcs. '' This season will focus on Storybrooke as the main setting, but will also show new realms and there will be the exploration of the Savior 's mythology. Kitsis and Horowitz hired two directors from their Freeform series Dead of Summer, Norman Buckley, Mairzee Almas, and Michael Schultz helm episodes of the season. Jennifer Lynch directed the eighth episode of the season, `` I 'll Be Your Mirror ''. In January 2017, ABC president Channing Dungey had been the first to suggest that the current narrative of the show would end with season six, regardless of whether or not there is a season seven. Shortly after this news, Jennifer Morrison revealed that the contracts for the original main cast members were expiring in April, expressing uncertainty about the future of the show and her participation in it beyond the current season. Robert Carlyle also expressed that he 'd have to make a decision about his future on the show by the end of that month. In March 2017, several sources had reported that four of the current main cast members in particular - Morrison, Carlyle, Lana Parrilla, and Colin O'Donoghue - were in negotiations to renew their contracts for a potential seventh season. In April 2017, Horowitz and Kitsis confirmed that a group of characters will indeed have their stories wrapped up by the end of the season in acknowledging the potential cast changes, saying : `` We planned this finale from the beginning of the year, so whoever stays and whoever goes... all those questions have already been dealt with. The audience does not have to fear ( anything feeling ) incomplete. '' On May 8, Morrison confirmed that she had declined an offer to remain on the show and that the sixth season would be her last, signaling the end of Emma 's time on the show as the main protagonist. On May 11, Rebecca Mader announced that she would also be leaving the show at the end of the season, citing creative decisions beyond her control. On May 12, season six was announced to be the last for four additional main actors : Ginnifer Goodwin, Josh Dallas, Jared Gilmore, and Emilie de Ravin. Thus, characters seeing their storylines wrapped up in the season six finale include Emma Swan, Snow White, Prince Charming, Belle, and Zelena. The season finale revealed that Henry Mills will remain a series protagonist, with the setting shifting to a later time period in which he is portrayed as an adult by Andrew J. West. Musical episode Main article : The Song in Your Heart In January 2017, TV Line reported that the series would feature a musical episode later in the season. Creators Kitsis and Horowitz had spoken about the desire to do a musical installment previously, but did n't `` even know where to begin. '' Kitsis and Horowitz confirmed the report in February. They have also since confirmed that the episode will feature 7 original songs, including solos by Jennifer Morrison and Rebecca Mader, as well as a `` sing - off '' musical number featuring the Evil Queen and the Charmings. Composers Alan Zachary and Michael Weiner will be writing the original numbers featured, with arrangements provided by the show 's long - time composer Mark Isham. Kitsis and Hororwitz spoke about the nature of the episode saying, `` It actually is a huge part of the mythology of the show and there are some big things that happen in the episode, frankly, it 's been one of the challenges of doing the musical because we never wanted to do something where it was just like a to - the - side, one - off thing, and then get back to the main story. We want to see it part of the main story, which meant we had to really plan out this season with some great detail. '' Casting Horowitz : There certainly are nods to the film that we all love so much, that we 're peppering in throughout. We 're, right now, focusing on ( Aladdin, Jasmine, and Jafar ). Kitsis : Obviously, I do n't think we would touch the genie. I would like to see a monkey but I ca n't promise anything. I think, whereas some stories, like Frozen, we were very faithful to Frozen, I think you will see Aladdin will have its own Once twist. -- Executive producers Kitsis and Horowitz on Once 's interpretation of Aladdin. Emilie de Ravin told fans that she will be returning for the sixth season. It was also announced later that Sam Witwer and Hank Harris have signed a contract to play two new recurring characters on the sixth season of the show.

She made her debut in the fourth episode of the season. In early July, it was announced that Raphael Sbarge would be reprising his role as Jiminy Cricket / Dr. Archie Hopper in the season premiere. The character 's last appearance was in the season 4 episode `` Rocky Road. '' On July 20, it was announced that Jessy Schram would be reprising her role as Cinderella in the third episode of the season.

On March 14, it was announced that episode 18 would introduce the Tin Man, played by Alex Désert, and the Cowardly Lion from the Wizard of Oz tale. On February 16, TVLine released casting call descriptions for two characters who appear in the season 6 finale, with potential to continue into season 7 if the show is to be renewed. One is a man in his late 20s - early 30s who `` was once optimistic and hopeful but now is a friendless, cynical recluse '' but `` still possesses a dormant, deep - seated spark of hope that waits for the right person to reignite it. '' The other is a 10 - year - old girl who `` comes from a broken home '' but `` those struggles have only made her stronger -- something which will come in handy when darkness threatens everything she holds dear. '' On March 8, it was announced that Andrew J. West had been cast in the unidentified male role, later revealed in `` The Final Battle '' as an adult Henry Mills. On March 9, it was announced that Alison Fernandez had been cast in the unidentified female role, also revealed to be Henry 's daughter, Lucy. On May 8, 2017, Jennifer Morrison announced that she had declined an offer to remain on the show through season 7 and would not be returning to Once Upon a Time as a series regular in the event the series was renewed by ABC. However, Morrison noted that she had signed a contract to appear in one episode in season 7. On May 12, 2017, showrunners Horowitz and Kitsis confirmed that five more cast members, in addition to Morrison, would not be returning to the show for a seventh season : Ginnifer Goodwin, Josh Dallas, Jared Gilmore, Emilie de Ravin, and Rebecca Mader. In their personal goodbyes to fans, both de Ravin and Mader cited the show 's decision to move forward in a new creative direction as the reason for their departures. Gilmore expressed similar sentiments. Meanwhile, Goodwin and Dallas had informed the showrunners a year prior that they intended to leave the show at the end of the sixth season.
