Based on one image where Neal’s grabbing his chest in the promo, and the fact that Zelena has the dagger and would probably want additional insurance with Rumple, I suspect that Zelena has Neal’s heart. And you don’t lose all free will just because someone has your heart, so Neal could break Rumple out.
