That's right, that's the best theory I've got so far. Both Ali and A need to kill one or the other. Because "two can't keep a secret till one of them is dead." Bethany can kill Ali and end the truth there, and resume Sara's life as her twin. Or Ali can kill Bethany and no one will know what happened that night.
