The only reason that Swan Queen is possible is because any random thing can happen on this show at any time.
Anything really could happen now that the reset button has been hit, and that is sort of my point. Neal was always planned to be Henry’s father and Emma’s true love since the start. He was the one meant for Emma. However, when the writers hit the reset button and killed off Neal in S3b, the story got a major overhaul. It seems like Emma and Hook are going to be headed down the aisle at the end of s6 (what with the wedding dress in the display case in S5 finale), but you never know with these writers. They’re tricky you-know-whats. If they don’t get picked up by ABC for another season, they could do whatever they want.
