Its' hard to say who gale is for sure but I think he is a
Dharma employee or an ex-empolyee. We don't know what he
did to after going through the vents
1.Did he put in the numbers?
2.What was with the random lockdown?
3.Why send out a search party to find something that would
ultimately prove your story wrong?
4. If he knew there was a chance that the group would
find the ballon and find out he's not Gale then why not
run away after the blast doors came up?
5. and what about the black light image on the door that locke saw?
Yes we did get some answers to some questions but that just made even
more questions to be answered.
I think that the supplies were sent for that hatch, maybe Gale didn't press the
button and these are supplies that were sent because of that.
Too many questions it hurts my head
P.S.
Did anyone notice the number on the lock box with the money in it? 1516
