I am liking Hook even more than usual this season. He has some of his inner angst back. He's not being the doormat. Ok, so he's still acting the way he is because of Emma, but at least it's now believable, and some of the dynamics of that relationship have been really well portrayed.

Now, as to him being the reason she's doing everything for Hook, I have a theory, based on the BTS pics from either 5x10 or 5x11, the one with him holding Excalibur with BOTH his and Emma's names. I think that back in Camelot, Hook somehow got a hold of Excalibur (now that it is tethered to Merlin), and killed Merlin (and I will go out on a limb and predict that it will happen in Birth). Assuming the tethering to Excalibur works the same as the Dagger, this would mean that Killian is now the Sorcerer (weird concept, right?). And Emma's comment about the blade not controlling anyone anymore (from the Sneak Peek) could be a reference that whatever she's doing is designed to release both her and Killian from control of the blade(s). And I get the feeling that whatever Emma has planned is not going to work as expected.
