George Weasley was a liver. Not liver, like the body part, but more like live-er. He loves to live and lives to love, as corny as that sounds. He lived because there was nothing to do but live and as long as he had to live, then he was going to live like living had never been done before. To George, living meant laughing—something so sacred as laughing is the entire reason for living. And thus, he laughed. He laughed every day of his life, until one day when he didn't. The day his twin brother, his better half, his accomplice, his fellow liver died.
Fred was always the outgoing one. It wasn't that George wasn't an extrovert as well, but Fred was always the funny one, the outspoken one, the fearless one. He had his flaws—in fact, he was reckless to a fault, but he was always the one people immediately turned to. George was no exception. He didn't know of life where Fred did not exist, and such was the life George would now have to live.
He fought valiantly, yes, but more importantly, he fought with heart. He fought, not with fear or burden, but with a light that could have been seen in his eyes even as the life left his body. In a lot ways, Fred represented everything that is seen by Voldemort as dangerous: humor, spirit, love, bravery, and even in death, Fred epitomized all those qualities. George had no doubt that Fred was wreaking havoc wherever it is that he ended up and was happy to be doing so. No, George Weasley was not afraid for his brother---he was just afraid that life had lost its spark and that he himself was doomed to this lifeless existence.
Ginny had told him that "Fred would kick your ass if you went on like this" and George knew that she had spoken the truth. Yet, what do you do when you know something, but you can't truly comprehend it? Still, though, he supposes things are getting better. Every once in a while, George remembers something—a stupid joke they once played together, and he, instead of crying, laughs. And in the briefest moment of that laughter, he sees hope. In that second of hope, he sometimes thinks that is the perfect opportunity to prank the crap out of both the living and the dead, with one twin on each side. Eventually, they'll meet and rule the heavens together.
In general, I'm not a writer, but I need to properly grieve for one of my favorite characters ever.
To Fred Weasley, who will never die.
"Give her hell from us, Peeves!"
