Scott only initially wanted Lightning off as an excuse to save him but after he saw how much Zoey hated him than he switched up to his back-up plan which involved manipulating Lightning to get Zoey eliminated. Cameron knew Lightning wouldn't live down him taking his immunity. Nothing indicates that Lightning voted for Zoey but there's evidence that indicates that he voted for Scott such as him smiling after Scott got eliminated.
