I'm sorry if this has been asked, but it just dawned on me while watching season one again. Locke walks ups to Sayid while he is analyzing Rousseau's Map, in vain. Locke gives him a compass which has a major magnetic malfunction, not sure if anyone remembers this but he then says 'I no longer need it.' How could he map out the island in a week!?
Anyone else think thats suspicious? Locke's wearing the same clothing, and in my mind very well could be a Locke 2.0 that we haven't seen do it yet. I think tonight time travel will be all over the place, because Locke would of had to be sent to 2004.
