So I’ve been wondering where to pose this question. Since it has to do with the timeline, I’ll pose it here. Is it possible that King Arthur could have been the corrupt king whom Hook sought to depose after Liam died via the dreamshade poison in Neverland? Upon first consideration, that may seem impossible (since Hook is over 200-years-old). However, might it be that Camelot exists in some sort of “timeless” dimension similar to Neverland?
Doubt it, when Hook and Arthur don’t give any indication that they recognize each other. Not to mention, wouldn’t Hook have warned them not to trust Arthur? Plus, it’s been made pretty clearly that Camelot really is in the same realm as the Enchanted Forest. It’s literally just a horse ride away. Also, again the “5 years” thing.
