AN: I tried to make the end as concise and emotive as I possibly could. If you have any suggestions of how it could be bettered, please PM me, I'll be glad to look into any possible improvements :D

Sirius was stationed cleverly. He was in the awkward gap between the pitch and the stands which enabled him to see the maze closely but remain unnoticeable to the rest of the crowd that had gathered. He was close to dying of hyperventilation now. There was no word of what was happening inside and McGonagall, Moody and the crew patrolling outside looked confused and worried. He knew something had gone wrong and even Dumbledore looked tense.
Suddenly a blue light was shining to his right. And then Harry appeared, holding Diggory who was unconscious by the looks of it and the Cup. But those details didn't matter. What mattered was that even from where he was stood he could tell that Harry was injured. He tried going over to Harry but there was a hoard of people surrounding him. Many people were saying many things, all incomprehensible. There was panic in the air. The he heard a shout, 'Merlin, Diggory! Dumbledore! He's dead!' and it made him forget everything else.
He started barking loudly, biting at people's ankles to get to Harry. He felt something soft yet huge gently hit his head. It was Hagrid, who told him to go wait at his hut for further instructions from Dumbledore. He growled. He didn't want to but he knew Dumbledore knew best so he went.
Almost an hour later, he was left in the Headmaster's study by a shaky McGonagall. He turned back to his human form and started pacing. He kept pacing and pacing. Back and forth.
Then Harry came in supported by Dumbledore. Sirius knew something bad had happened. But Harry... for a second he felt like he was standing at the entrance to James' house, looking at his dead body, guilt coursing through him.
But in reality he was looking at Harry who looked broken – his leg was hurt, his face streaked with dirt and his eyes... they looked so much in pain and in shock that he felt they belonged to a different Harry.
Then Harry started talking about what had happened in the graveyard. Sirius sat, listening in shock. He was disgusted and pained by how much Harry had to go through; his heart breaking at the sight of his godson, at the tale of what he'd had to confront. By the time he finished, all Sirius wanted to do was to take him away from everything that he had to face, to make Harry and himself forget everything that had happened and then return and personally hunt down Wormtail and every other bastard who had dared to hurt Harry and make them pay for it.
Walking, or treading, to the Hospital Wing, Sirius swore that he would protect Harry with everything he had. Not for James, or for Lily, but for Harry. He would protect his godson from any further harm. Even if it meant dying for him. So, when almost a year later he fell through the Veil at the Ministry, his last thought was not just temporary relief that Harry and Remus and the rest of them were safe but a huge pang of regret that he wouldn't live to do his duty regarding Harry through the war.
