I may have just missed the episode where this is explained, but in (i think "Deus Ex Machina") the vision/dream that Locke has that shows him where the Beechcraft is, there is a man (who kind of looks like Horace) who is standing there in a large coat (kind of animal fur looking) with his arm in the air, and he looks like he is waiting for someone to come out of the sky. And of course, at that second, the Beechcraft fell from the sky. So my question is . . . Who is this man? Is he related to the DHARMA initiative in any way? Is he a Hostile? Is he one of the people mentioned by Richard Alpert in addition to Widmore at the end of "Whatever Happened, Happened"? Please comment if you have any theories or know who it is.
