One year after the death of Killian Jones, the people of Storybrooke are stunned to see him return...but he is unaware of anything that has happened over the past few years. It takes place one year after the end of 5A (canon up until then) and it will be an AU, with season 5B divergence flashbacks that will explain how the story arrived at the point it is. If that makes sense.

Emma Swan is only just getting to grips with the whole fairy-tale thing, let alone the villains. She's already defeated the Evil Queen. But the Evil Queen's mother is a new story entirely. Not to mention Captain Hook. She will do whatever she has to to take him out. Until one day she wakes up in an entirely different bed, only to find out she's married to him. Captain Swan.
