Since this is IMDB, I’d take it with a grain of salt for now. If this is legit, then I guess Jekyll and Hyde were originally from Alice’s Victorian England, prior to ending up in the Land of Untold Stories. Victorian England and the Land Without Color were the two most suspected worlds for the characters before 522/523 aired, so this would line up. I honestly hope that Dr. Lydgate really is appearing, cause that gives us more hope for Anastasia.
