“I want to go home…”-MIB
I cant shake this question, where is MIBS home? Perhaps, their is no home. Perhaps, thats a con to coax more followers or to infect more. The people from the temple for example, their leader is dead, so why stay on the island. MIB claims there is plenty of room on the plane for everybody. Of course, Claire and Kate want to go home for Aaron. Sawyer, wanted to go home from the begining but had to jump off the helocopter, so that the rest of the survivers could make it off, mainly Kate IMO.
Bottom line, what I am trying to say is that MIB may not actually have a home. Instead he wants off the island simply just to infect the world. Perhaps, he has been bound to the island for many, many years, preventing him from spreading this infection.
