Think of this way why don’t you. If you were separated from your wife, your family, would your whole purpose be to find any means of getting back to them? Maybe the reason why his motivation to get back to Emma is because that is all his family. She is his family. Regina and Rumple? Are people he can’t stand and only puts up with because of Emma(in Regina’s case).
Yes, I don’t blame Hook for wanting to get back to Emma and to do whatever it takes. Not at all. What I blame is the writers for continually writing that same schtick. Either Hook is gone or Emma is gone and the other half has to get back to them. It’s old. But yes, if they do that plot, I don’t blame the characters one bit for acting the way they do. I’m simply saying I’ve seen enough of it and would like a different plot line.
I imagine they’ll have Hook even cursed have flashes of Emma similar to Emma in the season 6 finale. Like he could be haunted by this woman and she seems so familiar but he doesn’t know how.
