The US army is flying in an helicopter in the sky, we don't know what there doing, maybe looking for the island, whatever. They mysteriously find the island, when all of sudden they see a huge explosion. When they go down to check it out, we as the viewer, realize that this was the explosion from Jughead, Juliet blew up. The DI are running around pondering over not only about the explosion but what about the missing people? I.E. the main characters. Pierre Comes running and tells them everything. They realize what they have to do, build the hatch.
ITs a long shot, unaccurate, and pretty lame, but why not!
