I’m in the microscopic minority that thinks this is Jack (the casting call fits into the time frame of MRJ being cast), he’s described as a ‘thief’, Emma mentioned Jack’s story in the 3rd sneak peek as him having either a golden goose or golden harp – he apparently had a golden swan and a yellow bug…
That’s a cool little connection! 😉 I agree that the casting call for Jack was for Neal. Still think we may get the actual Jack and the Beanstalk story at some point though, whether it’s this character, or some separate character who is actually named Jack. Apparently Jorge Garcia has been given notice that he’ll be in another ep, and I think that’ll likely be the actual Jack and the Beanstalk story ep.
