If they're going to bring on a captain, there's like a 99% chance that said captain has crossed paths with Captain Hook xD Pretty much any character that's water-related has also interacted with Hook.

 Based on what was said at SDCC, it sounds like a Hook centric might also be Charming centric - he's supposed to find out some truth to his past. Because they were teasing that their friendship is going to be built up and then tested and I'd assume the related Hook secret that affects others will come up during that same episode. And if Colin and Josh already knew about those upcoming revelations back then, then it should be occuring relatively early in the season. Of course if that theory is true, then Captain Nemo or whoever will also have played a part in David's past and I don't really have any theories about what that flashback would look like.......
