List of episodes/Season 6

On January 28, 2013, it was officially announced that the show had been renewed for a sixth season. On June 30, 2013, storyboarder Jesse Moynihan announced that he would start season six the following week. Season six is not to be confused with the second half of season five; the latter of the two has been referred to as season 5.2 by the writing staff. The sixth season premiered on April 21, 2014, with the airing of the episodes "Wake Up" and "Escape from the Citadel."

Following season 5's cliffhanger finale, the reveal of Finn's dad was prominently teased in the promos leading up to the season premiere. It was also confirmed by the writing staff that a total of eight episodes in season 6 will involve Finn and his dad, featuring some of the show's most cohesive storytelling to date.
