I'm in a competition on another Tumblr site so I have more short next-gen pieces to share! :)
When he turns eleven, Fred's parents give him an owl of his own. It's a huge owl with dark eyes who sits around looking serious a lot. He names her Athena. Uncle Percy approves, Fred's dad rolls his eyes, and Fred blushes. Roxanne tries to feed it a couple of times. It bites her finger, but Fred always knows how to sneak food in.
When he turns twelve, his parents send him a huge package of Bertie Bott's and a couple books of Muggle tricks, teaching him how to mark his own cards. Of course, his roommates don't understand, and Mike stays convinced that he's trying to practice voodoo or something by poking holes in cards instead of little models of people. Gabe the Git tells Mike to knock it off, because that's mean, but Fred doesn't pay attention and concentrates on not poking himself with a needle.
When he turns thirteen, his parents send him a stretchable quilt. The coursework has been piling up and it nudges insistently at him when it's really time to give up and go to sleep, or flattens into a shawl to throw about himself when he just wants to cry. It's so much faster than waiting for Athena to bring back their "you're doing fine, it's going to be okay"s.
When he turns fourteen, he pumps his fist in joy at the breakfast table for a new songbook and self-tuning strings. He'd gotten his first guitar the previous Christmas, chipping in some of his own Sickles once he'd convinced his parents that was what he wanted. Gabe the Git is not a fan of rock or roll.
The year that Fred turns fifteen, Roxanne gets her first new broom. It's very nice for a second year, but it's a little bit old. She doesn't ask because she's too busy testing it out, but he has to wonder how long his parents have been saving it, hoping he'd ask.
The year he turns sixteen, he buys his own replacement owl after Athena kicks the bucket. It's a short, ugly little owl, and he tells himself he won't get attached to it, won't get distracted like during OWL year. He also tells himself it was a rubbish idea to name owls after Greek gods—better something he actually believes in. Maybe something nice and English.
Unfortunately, the patron saint of England is named George. That'd just be weird.
When he turns nineteen, Roxanne sends him a fake mustache and eyebrows, explaining it's a Muggle thing. The card says I miss you—we all miss you—but don't rush back to England. Take your chance to be someone who isn't Fred.
He doesn't use the new owl, Hamnet, to reply, because he doesn't need his dad knowing where he's at. He just says Thank you.
