Zelena (Once Upon a Time)
In December 2013, Rebecca Mader was cast as the Wicked Witch of the West. She made multiple appearances during the second half of season three and was promoted to a series regular for the show's fifth season. The role of the Wicked Witch of the West was written specifically for Rebecca Mader. It was announced that the writers had chosen not to continue with Zelena's storyline and Mader would not be returning for the seventh season of the show. However, Mader later revealed that she would be returning for multiple season seven episodes.
Once Upon a Time (season 6)
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.
