Ron was furiously pacing around his tent. He had already smashed everything he could. The battle had happened so fast, and nothing was left. His mind was screaming. It wasn't supposed to happen this way! Everything is gone and useless. All of his closest friends were dead. His wife, Hermione had been killed too. His Hermione. They were supposed to defeat Voldemort and live happily with children. Voldemort was gone, but so was Harry, his brother-in-law and best friend.
They were all fighting hard and winning when Voldemort apparated into battle. Ron was fighting Malfoy and Bellatrix Lestrange fire a killing curse at his back. Ron couldn't escape, but Hermione threw herself in front of him, shielding him, but dying before she hit the ground. He wasn't aware of anyone except her as he held her, kissing her expressionless face and burying his head in her hair.
Voldemort had seen him and he twitched with pain as the Dark Lord used the Cruciatus Curse on him. Harry had saved him by distracting Voldemort with a cutting curse that he barely dodged. Ron watched as they both shot killing curses simultaneously and an outward explosion of magic killed everyone in within ten yard of them and themselves. Ron was blasted backwards and lost consciousness.
Later Remus found him while searching for survivors and he levitated him back to the camp to his tent. He had wanted to stay there to comfort the poor boy, but was unable to because of other responsibilities.
Ron threw himself at his bed and shoved his face into the pillow trying to wake up from the dream he was living. He had to be strong, for himself and his family. He lay like this for hours, contemplating his future, until sleep finally came, and he drifted out of consciousness.
Charlie was outside of his tent as Ron had expected, and they each silently acknowledged each other. Ron walked with him through the huddled mass of tents to Remus's tent to find out exactly what had happened. He quietly entered the tent as he saw his mother sitting on the couch with Remus holding her. The graying man was obviously trying to comfort her, so Ron sat down too. "Mum, are you okay? What's happened Remus?"
Remus sadly shook his head. "Your father's body was found near Hogwarts grounds. He was protecting the castle, and was overwhelmed with Death Eaters. I daresay he took a lot of them with him. Your sister's baby had sophistications and Ginny didn't make it—"
Remus was interrupted by both Charlie and Ron. "NO! Not Ginny! How could this happen? But…." Ron ran out of the tent screaming. He continued out of the campground and away from the battlefield. How could this happen to him? Everyone close to him was dying and yet he should have been dead and wasn't. He heard yells from a pursuer, probably Charlie, but he refused to stop. He pointed his wand at anything he could and yelled "Reducto!" destroying everything around him. Charlie tackled him and forced his wand out of his hand.
They slowly made their way back to the campground. "It wasn't your fault Ron," Charlie said, "Sometimes things like this happen. We didn't have a decent medi-witch with us. I'm devastated too, and I know you have a reason for it, but you need to calm down and understand what has happened and what we are going to need to do. Harry and Ginny…um…left the baby to you and Hermione as legal guardians. And Hermione, well, you are the guardian of Sirius Albus Potter."
"What? They left the baby to me!" Ron screamed, "They're bloody crazy! I mean he is my nephew, but I've never been able to treat anything well. Pigwideon was psychotic, Scabbers turned out to be a mass murderer but I still have to raise this baby! Everything happens to me! What did I do to deserve this?"
Ron held the baby in his arms. If only this was Hermione and my child, he thought. That was what should have happened. Death had to steal her away and leave him behind. He struggled inwardly with himself and his emotions. Hermione was lost, and had only had so much time to love her. The baby was awkwardly silent. It should be crying, if he was the one holding it. From what he could tell Sirius had Ginny's hair and Harry's eyes. It felt good holding him, but this should have been Harry and Ginny's job. The baby looked up knowingly into Ron's eyes and flexed his little hands gently. He gurgled quietly at Ron and smiled for the first time. At that moment Ron couldn't stand it anymore and tears went streaming down his face.
Tears of grief, loss, anger, and happiness rolled down his cheeks as the blissful child glowed with joy. His emotions overwhelmed him with acceptance of what was happening and what was to come. He clutched the baby close to his chest and sat there, crying away his problems. Sirius sat there waiting and ignorant of the devastating recent events in his uncle's life.
Now that the war was over Ron didn't know what would happen next. He had always expected that this time would come, but he hadn't expected that Hermione wouldn't be with him. He had always imagined the parties, fame, and riches following the destruction of Voldemort. He would play quidditch and live happily with Hermione and their multitude of children. They would live near Harry and Ginny, who would both have successful careers and their children would play and grow up together. Their children would go to Hogwarts and have fun together just as their parents had. Then they would all grow up and live great lives, and have children. And He, Hermione, Harry, and Ginny would grow old together.
Nothing went according to plan. Hermione and he would never have children. Harry and Ginny would never be able to enjoy Sirius. It would be him living a miserable life alone. He would try to raise Sirius well, but it wouldn't be the same. No quidditch for him, he would settle into a boring Ministry job like his father. Sirius would be raised by himself with only adults around him. He would hopefully have a better time at Hogwarts, but Ron would be stuck at home without anyone to remind him why his life's worth living. He would grow old and guiltily wake each day while his friends woke for the last time years ago.
Why did fate have to fall like this? He had nobody to talk to who he could share his feelings and problems with. And he had nobody to hold him and tell him things will get better. Lying in bed he felt so empty without the weight of his love beside him. How could he live his life like this? There is no way he will feel that way for somebody else, and there is no way that things will ever be the same. Everything was so boring, so lifeless without everything he had come to know.
He wished that Hermione hadn't save him from that curse. Of course she would be stuck in this position, but she would know what to do and would be able to live out her dreams without him. He was so dependent on her and his friends that without them it seemed all was lost. I can't imagine what would happen if I had never met them. My life would have be useless and not worth living. Now that's what it actually is. He would kill himself if it weren't for Sirius.
Molly Weasley had been grieving for days. Her husband was gone and she had no clue how she was going to manage without him. He was always so strong and he always knew what to do. Without him she was nothing. Her daughter, daughter-in-law, and son-in-law were all dead. They were all so close, and now Ron is alone. She had always wondered what life would be like after Voldemort was gone. Most of what she had pictured was happiness and plenty of grandchildren.
She wanted to see Ginny grow up and face the challenges of the world, and be able to strive as an adult. She had hardly been able to graduate from Hogwarts before she was killed. Ginny never even got to hold her baby and neither did Harry.
Harry never was able to live happily without a care. He was abused as a child, and during his Hogwarts years he was happy, but he was under a lot of stress with not only schoolwork, but Voldemort as well. He had never been able to just relax and watch and absorb the wonders of the world.
Hermione was never able to have any children. She would have been a great mother and loved her kids greatly. She was only able to express her feelings for Ron the last few years and the relationship was strong, but they hadn't had much time to enjoy it. They had spent most of their relationship trying to defeat Voldemort.
Ron had so much potential. She was worried about him more than anyone else because he was the least able to live by himself, and he had everyone close to him killed. He had never been able to experience everything the others hadn't but he had to live with that fact. He could never see any of his best friends again, or hold his love in his arms. And now he has Sirius to take care of too. I hope that he realizes that he is needed in this world and that he can still live his life.
