Well, In Henry's defense, There's not much to flashback to for him. We've seen probably the only Henry flashbacks we'll ever see with "Heart of the Truest Believer", "Save Henry", and "Going Home". And only one of these ("Going Home") was actually focused on Henry, the rest were more Henry being present (as a baby).

Now, back to the episode at hand (or hook?). Dark Waters is almost certainly a reference to some type of sea-faring story, and likely a pirate story (though not absolutely necessary). And since we get 1 to 2 Hook Centric episodes per season (whether we want them or not, though I am a fan of Killian), it seems fair to presume that this will somehow involve him. He would NOT necessarily need to be in the back story, but it could involve him being involved present day in helping to complete the story. It would not have to be some "Dark Water" secret for Killian, just some present day character building on his continuing redemption story.

The real question is who else will be involved? And will we possibly even see some of Killian's other crew members (Smee, for example). I think the biggest candidates for sea-faring stories are 20,000 Leagues or Moby Dick, with outside chances at either Treasure Island or Blackbeard. Other possible candidates, though, could include "Robinson Crusoe" (one of the inspirations for Lost, by the way), or "The Gold Bug" by Edgar Allen Poe (and this story features Captain Kidd, another famous pirate).
