During the current season of ABC's LOST, we are seeing several characters living alternative lives off the island. Why are these characters heterosexual both on and off the island? For example, John Locke is married to a woman. Why? Jack was married to a woman and had a son with a woman. Why? Sayid is attracted to a woman. Why?
Why did it not occur to the writers create truly alternative and realistic lives for John, Jack, Sayid and others off the island?
