Thoroughly confused on ending. The guy at the end I believe is flagg. Might be trashcan man but his name Russell Faraday initial rf. Unless trashcan taking that name to be like flagg. My life for you. So 1 st question is who is that. 2nd is how did he survive the blast at ground zero. 3rd is he was in Las Vegas so how go from middle of desert to a coast somewhere. Just doesn't add up at all.
