Hugo Arthur Weasley
1.) It was always HugoLouisandLily, right from the very beginning. They were best friends, troublemakers, and petty thieves from the minute they were able to walk, and Hugo can't think of two people he trusts more than his cousins.
2.) At every Sunday Dinner at The Burrow, Rose and Hugo sneak away from the rest of the family and do the word puzzles in the funnies section of the Prophet. It's their own little secret, and when they're done with the word jumble and the crossword, they go back to the rest of the family and pretend like they weren't missing for two hours. Hugo likes this tradition because it's something that is theirs and theirs alone, and because Rose is never nicer to him than she is when they're working on a puzzle.
3.) He likes girls, and he likes taking them home after a hard day at work, but the thing he likes in bed most is a glass or two of Vipertooth Vodka with cranberry juice and a great mystery novel.
4.) He gets the ear piercing when he's fifteen and his mother goes ballistic. He gets the eyebrow piercing when he's seventeen, and his mother doesn't speak to him for a week. He gets the Hungarian Horntail tattoo when he's twenty-three and his father tells him to just never mention it to his mother.
5.) He's a little jealous of Rose's relationship with their dad, but being his mother's favorite child seems to even things out a bit. And besides, both he and Rose are mixes of both their mother and their father: she got the activism gene from their mother and the Quidditch talent from their father, while he got his dad's sense of humor and his mum's library addiction.
6.) When he's bored, Hugo likes to think of theme songs for people. Lily's is Saturday Night's Alright for Fighting. Louis' is Under Pressure. There's one that he has for both of his parents is called Into the Dark. He's got a list, somewhere in the clutter of his desk, that he has all the theme songs he's matched his family and friends to. Maybe one day, he'll show it to them…if he can find it.
7.) Hugo A. Weasley never gets married and he never has children, but he loves his niece and nephew and godchildren more than anything, and he would truly and honestly die to protect each and every one of them.
8.) The happiest day of his life isn't when he graduates second in his class at the Auror Academy, or the day he makes his first arrest, or even the time he kissed Violet Finch-Fletchley under the mistletoe at the Auror Christmas Ball. It's the day that Auror Potter – because the only time he's Uncle Harry anymore is when they aren't at work – came to his desk in the bullpen and said that Louis was going to be his permanent partner.
9.) When they're on the job, Louis is Talk and Hugo is Action, and that is just the way he likes it.
10.) While Rose and Scorpius are getting married in the garden of Malfoy Manor, Hugo is comforting his sobbing, shaking mother in the master bathroom of the mansion. They watch Ron give her away and watch Rose become a part of the Malfoy family from a window high above the celebration until Hermione Weasley calms down, and Hugo promises over and over again that he won't tell anyone that his mother had a panic attack the second she saw the Malfoy's grand ballroom.
He loves his sister more than anything, but a small part of him hates her for the fact that she would willingly marry into a family that would hurt his mother like they did.
