That was my thought too; odd that it is also the first episode in which Jasmine will appear.
So maybe the finale episode for Jekyll and Hyde; and the introduction of Jasmine and bringing Aladdin into the story more fully since the first episode of S6.
I’m thinking Jasmine’s first appearance in 604 will be brief, and perhaps her and Aladdin will get their own centric sometime afterwards. Anyway, guess 604 being a Jekyll and Hyde episodes makes sense, with Dr. Whale’s return just recently announced.
