During Adam and Eddy's Facebook Chat today, Amy Hood (@Amylia403) asked about Jafar and Once Upon A Time In Wonderland.
Amy: "How will the current timeline for Jafar fit in with his Once Upon a Time in Wonderland timeline?"
Adam: "It fits in exactly with that. When we see Jafar this season on Once Upon a Time all the stuff that happened in Wonderland ... all holds true. But we're now into a new chapter both for him and for our characters, and Aladdin and Jasmine, who are going to meet for the first time this season."
Eddy: "I agree."
