I've always wanted to write a story showing Fred on his brother's death. The story is told from the POV of Roxanne, George's 2nd child. Quinn and Maddy are also children of George.
Disclaimer- rights go to J.K. Rowling, only Quinn and Maddy names I came up with.
One of the only times I ever saw my dad cry was when I was 5 and we were cleaning out some back rooms in Grimmauld place. I was exploring and found a boggart in a drawer, it popped out at me and turned into the Dark Mark. I screamed and my dad rushed into the room.
All of a sudden he appeared on the floor, obviously dead with blood coming out of the corner of his mouth. I screamed again, but was very confused because my dad was right next to me.
I turned to see him collapsed on the ground shaking with sobs. this scared me even more, my dad never cried. My mom rushed into the room. She went white when she saw my dad on the floor dead, but when she saw the second him who was next to me, she stepped forward. The dead dad disappeared, turning into a dead Quinn, then me, then Maddy until she shouted, "Riddikulus!"
Then she scooped me up and took me out of the room. She told me that the boggart turned into whatever you feared most, and what my dad feared most was his twin leaving him. She said the dead man on the floor had been my dad's brother, uncle Fred who had died in the war.
Then she sat me down and went into the room to help my dad. I remember feeling terrible for him. What I feared most was going back to the days of was, never knowing if the Dark Mark would be over your house when you returned. I thought how terrible it was for my father, that his greatest fear had happened and he couldn't stop it. He and Fred had also not died together, they had been right next to each other one second, and the next Fred was gone , but my dad wasn't, he was left to carry on alone. He was left to have a family, to grow old. But he was alone, even with his entire family, he was completely alone.
