I still cannot get over that scene with Hook and Neal in the hospital. Despite everything the two of them have been through, from Milah leaving with Hook to their love of the same woman, they were able to finally put aside their differences and hug it out. They needed to hug it out and actually talk their issues out before something else bad happened to Neal.
Hook loved him like a son once and we know that he missed him when they all thought he had died. When they split up, when Neal was still a boy, they had their issues. Obviously. And each time they came together after that, they had more issues. But they also had a deep respect for one another, a kind of love, too.
So, let’s remember that Emma and Henry weren’t the only ones that lost someone tonight. So did Rumple. And so did Hook.
