In August 2014, Maleficent was reported to be the main villain for the second half of the season. Prior to the season premiere, a special aired recapping the previous three seasons, and finished up with the introduction of the Frozen storyline. The theme for the season is `` Never give up on the people you love ''. Adam Horowitz initially announced that the 2 - part episode, `` Smash the Mirror '', would air at the earlier time of 7 / 6c and will be two hours long, however this was later contradicted by the official Prime Time schedule which stated that it would premiere in its usual spot of 8 / 7c, the official ABC press release for the episode and the Futon Critic also supported this start time. Horowitz later clarified via Twitter that the extra hour was in addition to the already announced 22 episodes. He also confirmed that the winter finale would air on December 14, 2014, and later confirmed that the show will return from winter hiatus on March 1, 2015. On March 15, 2015, Horowitz confirmed that the last 2 episodes of the season will form a 2 - hour episode. It has been confirmed that, unlike the Frozen arc, the villains of the second half of season 4 will come from `` ( Once Upon a Time ) mythology '' instead of from their respective movies, so their origins will not be how people remember them, in particular, creator Adam Horowitz stated that `` ( Once ) Cruella may have a different backstory than the one that people may remember from the movie '' and explained that Maleficent has already been slotted into the mythology in previous seasons. Another special, similar to the special that aired between the season 3 mid-season finale and premiere, aired an hour before the mid-season premiere on March 1, 2015 and was titled `` Secrets of Storybrooke '' and narrated by starring cast member, Jennifer Morrison. The special focused on the topic of what it takes to have familiar fairy - tale characters who have been flipped on their heads from their respective origins. Casting After Once Upon a Time in Wonderland was canceled, it was reported that Michael Socha, who portrayed Will Scarlet / the Knave of Hearts on the spin off, was in talks to join the main cast of Once Upon a Time as a series regular should the series receive renewal for a fourth season, this was later confirmed on April 20, 2014 and on May 8, 2014, Socha was hired following the season 4 renewal.
