I agree that it's Henry. As someone else pointed out in the other thread, the prophecy of Henry being the Dark One's undoing still hasn't came to pass. So it all fits. Henry is the guardian which will make him immortal once the Dark One has transferred his power to him thus saving him from the poison and fulfilling the prophecy of being Rumple's undoing.
