They said that they won't follow the books' storyline. Even if they had Ali have a twin, the twin being alive would mean that the storyline is different from the books'.

I thought more along the lines of an Irish Twin, but that would not work unless the older sister just turned 17 and Ali was turning 16 at the time of her disappearance. If her birthday is the date posted in June, then this could not work.
