I thought ‘Peter Pan’ wasn’t in the public domain – & ABC/Disney would have to pay the copyright fees to be able to use any likeness of the character – & so they haven’t bothered with using any of the characters from the novel. I’m not saying they won’t use Peter Pan – but at this point in time, I don’t see Disney shelling out the big bucks to be able to use the character’s likeness. They used to own the rights – back when they produced the animated movie but I’m pretty sure they let the rights go & they returned to the estate / holders of J. M. Barrie’s copyrights.
( Long story short – I don’t think we’ll be seeing Peter Pan until season 2 and rather late in the season at that. ) / Just my two cents.
