Voldemort decides that the best way to defeat Harry Potter is to remove all his supports. Not by killing them, but by making them turn against him. If Harry is left alone and friendless, his will to fight will disappear – or at least leave him a lot more vulnerable and open to attack. How does he do this? Does it work, or does it fail miserably? If it works, does anyone unexpected step in to fill their places? If it fails, where does the plan go wrong?
