Was Henry kidnapped in order to bring the Saviour to Neverland?
This has been discussed a bit before, (though buggered if I remember what thread it was in), and I sorta liked the idea, but ended up deciding against it, because I think that Henry is needed in his own right as a “Saviour” for NL. If PP just needed Emma, he would have had Emma kidnapped instead of jumping through hoops to get Henry.
Given that in ASOTM, Felix told Bae that he was lucky he’d get to live, I think that Henry is probably needed in some sort of sacrificial way to rejuvenate NL. In a recent post, PriceofMagic suggested that PP might pretend to be Henry’s friend, until such time as he backstabs him, and I could definitely see that happening. If PP tells Henry that it’s his destiny to save NL, Henry would think it’s the coolest thing ever, because his mum saved SB, and now he gets to do the same thing, and be a hero just like he’s been dreaming of.
As for why PP needs Henry in particular, I think it’s because of his unique genetic makeup. His mother is True Love Incarnate, inherently magical, and I think Bae’s bloodline was required because there’s a blood tie between PP and Rumple being brothers. (Not everyone buys into that brothers crack theory, but it’s my current headcanon.) The magic from Emma, plus the blood from Bae, makes Henry the only kid who ever lived who could do whatever it is PP needs to be done.
Their continued promotion of Emma as “The Saviour” probably has more to do with marketing than anything else. They had to give each member of the JR6 a “label” to make them sound like a snappy little team of avengers, and Emma was already known as “Saviour”. That being said, she is going to save Henry, so she’s technically still acting like a Saviour, if not the Saviour in this case.
