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.
