In a recent interview, co-creators Eddy Kitsis and Adm Horowitz say that they loved Robbie Kay's character Peter Pan because he was so much fun to write. They would love to see him back in a flashback, however, it might not be until next season that that would happen.
There is so much of Rumple's past that fans don't know that is hinged on his childhood with his father or the lack thereof that there is plenty of room for flashbacks that it seems almost impossible not to have Peter Pan back on the show. He could also be tied to Henry in some way since he was held captive. The possibilities are endless.
Are you excited at the possibility of seeing Peter Pan return to "Once Upon a Time?" Would you rpefer a different dead character to return instead?
