Louis William Weasley
1.) His two best friends growing up are Lily and Hugo. It doesn't hurt that they're all just a couple months apart, or that Hugo can make him laugh like no one else, or that Lily has the best ideas ever when it comes to making up games and stories. They're their own little trio, and not even separate Hogwarts Houses can keep them apart.
2.) To Louis, freckles are great. When he was a kid he loved connecting the dots on his arms and legs when he got really bored, trying to see if they made any shapes. He tried connecting Dominique's freckles before, but she didn't understand the fun in it and made him stop, and Louis still doesn't understand how she could get so upset just because she had a few ink lines on her arm. Of course, Victoire didn't mind so much, and would draw on him and let him draw on her, and then tickle him until he was crying from laughing so much.
3.) Astronomy was his best subject in Hogwarts. Charms could be mispronounced, Potions could go awry, History of Magic could put you to sleep, Care of Magical Creatures could result in a bad case of rabies, and Transfiguration could result in sprouting tusks, but Astronomy never changed, and he liked that.
4.) He once found an old picture of his Nana Molly in her Hogwarts years, standing in front of the Hogwarts Express with a grinning, raven-haired girl that had a regal sort of look about her. He thought that she was the most beautiful woman he'd ever seen, and no one had the heart to tell him that the girl in the picture was a young Trixie Black, captured forever in the time long before she became Bellatrix Lestrange. To this day, he still doesn't know.
5.) When they're twenty-three, he, Hugo, and Lily get drunk and decide to get tattoos together at one of the cleaner places in Knockturn Alley. Hugo gets the Horntail on his back, Lily gets the shamrock on her hip, and Louis gets a wolf paw right over his heart. He knows it's kind of silly – not to mention a bit weird – but he likes to think that the tattoo protects him from harm…like it's a symbol of his guardian spirit, or something.
6.) Truthfully, Louis started smoking because Victoire did, and only because she made it look so unbelievably cool. He continues to smoke because really, it's his only vice, and with a job like being an Auror, he needs an outlet for his stress.
7.) His father's scars never scared him, like they do some people. Louis found the twisted skin fascinating, like freckles and stars, and liked to imagine he saw pictures in them. When he was younger, his dad used to ask him every morning what he saw in them that day, and Louis would always tell him something different, even when he didn't actually see anything, just because it made his dad smile. And the way he figures, it wasn't lying if it was for family.
8.) He actually cannot speak French. Sure, he knows a few words here and there, and whenever his mother or Aunt Gabrielle or his grandparents talk to him, he can understand them, but he can only respond to them in English. It bothers him a little that Dominique took to the French side of their family so whole-heartedly and he can barely string a sentence together, but she's his sister, and he loves her anyways.
9.) When they're on the job, Louis is Talk and Hugo is Action, and that is exactly the way he likes it.
10.) Louis graduated first in his class at the Auror Academy, has six commendations from the Minister himself, and an arrest record that puts even Alastor Moody's to shame. He works with his best friend every day, has three wonderful children and a beautiful wife that love him, and runs every morning in the park by his home. He is happy, he is successful, and he is respected – if not loved – by nearly everyone in his life.
But he would give everything up, everything, in a heartbeat if it meant that he and Hugo could see Lily one more time.
