The candy killer storyline has come to an end on Once Upon a Time. “Chosen” focused on Zelena and her wicked past and the target on her back. While Zelena grappled with her past mistakes, Detective Rogers hunted down the serial killer. Nick (Jack/Hansel) was arrested and then killed by Dr. Facilier. This story arc was pretty dark for Once Upon a Time. Will the last half of the season lighten up, or will Dr. Facilier lead a new dark storyline?
