I think it is Greg Mendell in the other cage and I think Pan has been playing him since he was an orphan all those years ago.
If Rumple can cut away his shadow and survive then why would Greg be dead?
As for Hook/Emma/Neal story... I'm torn. I LOVE the chemistry between Emma and Hook (I mean not only is he a hot guy but now knowing his back story I love the character even more) BUT I also had wanted to see Emma and Neal together for a bit to see how they really relate to each other. I'm so hooked on this show. (and the Princess Bride reference.... made my night, well, along with the kiss).
I would also like to see more with Henry character and how things are going with him. The drawing on the ground of a house gave me hope... lol, for his hope!
This show needs to be two hours long not 43 super short minutes!!
