@Rumplegoldfan, once again you climbed into my head and said everything I was thinking!
I think Killian’s going to tell Emma about the WW immediately just like he did in NL when he learned about Neal. They did show some Snowing parallels but – CS is NOT Snowing. They trust each other. They solve problems together. CS knows they can say anything to the other and it will be better than keeping it from them. I think Emma told Killian about not wanting to live in the past the MOMENT she realized how she felt. Charming STILL hid his dreamshade near-death from Snow after all this time. I think the parallels were shown to signify we AREN’T going down the same road again.
I think we’re foimg to see that Emma’s abilities far outmatch even Zelena’s. Emma’s like DARK ONE powerful but with white magic instead of dark magic. They made a big deal out of showing Zelena has never truly loved or felt loved – it’s the root of her envy. And I think because of that the greatly underestimates Emma’s ability to break her curse. Especially one as seemingly fairly simple in comparison to what she’s got planned.
And I’m still calling it – HE TRADED HIS SHIP FOR EMMA! If he just left it at the docks I’m going to be seriously PO’d!!!
