I've just got around to watching the season 4 premiere. Excellent... been missing Lost.
Also, because of the fact I hadn't watched the premiere yet, I hadn't read any of this thread yet... so I started perusing it tonight. This video was originally posted TonyD.
It backs up a theory that I have been more and more convinced of since season 1 (and still get the snickers from my friends, but not after I show them this video
). I also mentioned it after the season finale in season 3's thread
here. Mark my words... "the Losties are doubles... possibly everyone on that island is a double, or clone. It's probably why they can't reproduce. Maybe somehow the island's magnetic properties rip matter apart and create these doubles. Something like that could also explain Richard's agelessness. Maybe he keeps getting cloned, or doubled, every few years... maybe it's Richard v.8.6 ."
