You know, in my little “world of Lost” I wouldn’t get so surprised if jack Sparrow would pop up in an episode, then disappear, all without any reason or explanation Probably yet another dozen or so new theories would pop up about why it happenned, and they’d get some new viewers from among the PotC fans Actually, they could write in regular “visitors” from another movies and series, and finally turn the whole thing into a big joke. Oh wait, it already is one.
