Summary: Severus Snape didn't get the message until it was too late, but the boy had to die in his arms before the war was over.
Drabble 13: Goodbyes
This isn't the fate that Severus Snape expected for Harry Potter. He doesn't realize at the time why Harry Potter was hugging him before the battle started. He told Severus Snape that he was the bravest man he possible knows and that he hopes when the war is over that they could both help each other out. (Severus Snape doesn't exactly know what that was about until later, until when Harry dies in his arms and the war over). The war sirens were sounded and he knew that the death eaters and the dark lord was approaching around where they were and that everyone will be hurt, including himself and the boy. Not everyone at Hogwarts trusted Severus wanting to help the boy who live instead expecting him to stay with the death eaters. But Harry knew better and persuaded everyone how Severus Snape was a better person and that he was always on their side.
Severus ended up helping Harry fight off the enemies, so many of them. And that was when he saw it. How some random death eater shot out the Avada Kedavra curse and that Harry's body was on the ground. He never realized what Harry was trying to say about him. He hugged Harry (as he was crying) and realized that this wasn't the outcome that he wanted. That he wanted Harry to survive the war and grow the friendship that they had (turns out Ginny Weasley was carrying Harry's child in her belly, and she told him how much Harry wanted them to become a family). In the end, he raises Harry's son as a grandson he never had. He didn't realize the message until it was too late.
