They Will Suffer for You (слэш)

The true loyalty of Snape eats at Harry, fueling the single spell taught by that very man to finally kill Voldemort. The death of the man that spent half his life dedicated to Harry is something he cannot bear and he snaps when he sees the Death Eaters scatter like roaches. The celebrations are cut short as The Chosen One hunts down Death Eaters across the devastated school grounds, siphoning life and magic from the fleeing criminals. Once he makes it to Snape's side, he cradles his lifeless body in his arms, unaware of the collected magics and life energy flowing into the man in his arms.
