Re: Lost 5x04: "The Little Prince"
Um, I just realized something.....Walt totally has to get in on this time-travel stuff at some point so he can "drop in" on Shannon and Locke.
Although he was younger there. I think that's more of Walt's ability to appear places he shouldn't be (which seems to be the other thing about him besides the bird thing). Of course, time travel would be nice to explain the whole "Tall Walt" talking to Locke at the end of Season 3.
