I don’t think Hook or Neal would intentionally set out to harm Emma or her loved ones but obviously, Wicked could play either one of them in some way. She’s apparently the type to sidle up to people, make them think she’s on their side and then use them. Sort of like what RUmple did right, in S1 with using Regina and Snowing to get what he wanted? Well, I could see a similar thing happening here where Wicked might use either or both guys in some way to pull off her scheme–or for all we know there’s even ANOTHER player on the board using people.
It’s not a chess match–it’s a free-for-all apparently, with Rumple, Regina, Pan, Cora all having long range plans that affected many lives, now we hear about Glinda and Wicked. Then there’s that Sneaky Blue, and the name dropped Black fairy out there–who even knows!
“If I had a world of my own, everything would be nonsense. Nothing would be what it is, because everything would be what it isn't. And contrary wise, what is, it wouldn't be. And what it wouldn't be, it would. You see?” -- Lewis Carroll, Alice's Adventures in Wonderland & Through the Looking-Glass
