I was just thinking, and sorry if this has been posed already. But in the underwater scene from LA X, we see the swings in Dharmaville. This would mean, theoretically, that the island could not have sunk as a result of Radzinsky hitting the pocket of energy. That is, assuming that something strong enough to sink an island, would have first whipped those metal swings down the hole. Thus, the island has to have sunk from either Jughead, or something that has not been shown to us yet. Thoughts?
