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.
