The PR is really weird but interestingly enough, Young Henry, which we have all assumed to be Sir/Wish Henry, is just reffered to as well...Young Henry, but Wish Rumple is referred to as wish Rumple. It could really just be a flashback to early in Henry's adventures where Wish Rumple pops up, maybe asks something to do with the Author powers, fails or gets tricked (like Nick described in Chosen, maybe even young Hansel will be in it).

Interestingly enough, Pan, Cruella, and the Apprentice who we have all just assumed and have lowered our expectations for to be anything more than Wish Realm counterparts, could still be in the Underworld. They all happen to have been stuck in the Underworld, and maybe Wish Rumple or Wish Henry (who gets the quill because...reasons), release them briefly (hence Cruella's seeming appearance in W!Rumple's castle based off of the trailer). In Pan's case, I think he could have been released by Arthur from the River of Lost Souls, but then put into that thingy as punishment, and because he's like totally evil.
