Continuing to follow in the footsteps of Once Upon a Time, Wonderland reveals layers of people’s relationships that ultimately change the course of everyone’s actions. Jafar’s mission to change the course of magic forever becomes a bit more complicated when he discovers a few more holes in his plan than he would like.

Previously on ‘Once Upon a Time in Wonderland’

The Knave is missing one crucial part of his body required for Jafar to take over the full magical dominance he seeks. Ripped from his chest years ago, the Knave no longer lives with a beating heart inside of his chest. Years back, the Knave sought out Cora to take his heart from him and prevent the feeling of heartbreak from ever returning. Alice and Cyrus take a trip to Storybrooke to retrieve Will’s heart and take in all the wonders of modernity around them.

Upon their return, Jafar and the Jabberwocky are able to take the heart from Cyrus, but for some reason Jafar’s staff holds a certain loyalty to Cyrus now. (Um, perhaps because Amara senses it is her son?) Jafar returns with Will’s heart and proceeds to kill Anastasia in front of his eyes. Talk about a villain, huh?

Synopsis ‘To Catch a Thief’

“In flashback, the Knave hunts Alice per Cora’s directive and he finds himself striking a deal to get his heart back, while in present day Wonderland, Alice and the Knave’s friendship is tested as he does Jafar’s bidding and steals from her. Meanwhile, the Jabberwocky attempts to free herself from Jafar’s control and Jafar is confronted by his former partner.”
