Right guys remember that episode when Jin and Mr Eko were looking for Michael. On the way there they found a stick through Goodwins chest, he was dead.
(This did not happen this is just a reminder. We now know the others wear normal clothes, they do not wear the rags, bear footed, long beards. We know they just put this on for the losties.)
Jin and Mr Eko walked a bit more and then they hid in the bushes, because the others were coming. At this time Mr Eko put his hand overs Jins mouth when he was speaking. So how come the Others were wearing the rags, long beards and were bear footed. Does this mean they possibly knew Jin and Mr Eko were coming that way?
