I think it was Visser Three who said, <You six humans...You five humans and Andalite.> Or something along those lines. Which makes me wonder. Who was the six Animorph, if not Ax? Who was the extra member in this group that was bound to fail?
What if it was you?
If the Ellimist changed things, I wonder who the fifth Animorph was. Rachel wasn't supposed to be there. Who's to say she would have ended up there again.
