Vincent sat on the beach, watching the rescue plane as it flew overhead. As it landed he turned his head to look back at the beach where all of the graves were placed.
Kate, Jack, Sawyer, Walt….. Everybody had died; he was the only one left. The people on the plane walked around the beach, looking at all the graves, taking down names of everybody. They looked at Vincent and talked quietly for a while, before one went to the plane and took out a handgun.
The man took aim at Vincent and shot, ending his life on the island like the rest of the others. Only Vincent had escaped the horrible wrath of the others, the black cloud and the polar bears that inhabited the island. Now nobody would know what lies beyond the woods. They will only be lost once more.
They will be Lost forever. If only the rescue plane had come sooner, nobody would be lost ever again.
They will never leave the island, and nobody ever will. The people on the plane will survive for a while, and then die off, awaiting the new survivors to come. They are all dead as soon as they set foot on the island. Nobody leaves and nobody lives.
So nobody is really a survivor, just another character in the little story of life, one dies, another is born.
