There's Nothing Holding Me Back by Shawn Mendes "If you can't have it all, then why have something to begin with?" - Xavi Pearce Maack
Xavi was the second to be born between him and his brother, Olivier. Xavi thought nothing when Valerie was born, and thought she'd be either an annoying sister, or a better partner in crime. When they (Olivier and Xavi) were five, Arius and Bexalyn decided Xavi would be a better heir for the family household because he was quite smart and resilient for his age, and compared to his brother. At six, Arius put both Xavi and Olivier into advanced lessons for special witches and wizards, which both boys excelled in. The Sorting Hat sought him out as a clever young boy, but too ambitious and sly to be in Ravenclaw, so he was obviously sorted into Slytherin. He would get picked on for wearing glasses, even though it shouldn't be a big deal, so Xavi only wears them when he reads. He's farsighted and enjoys reading too much for a Maack. Xavi thought looks didn't matter before friendship. He'd start hanging out with fifth, sixth, and seventh years when he was in his third year, teaching him how to be a "true" Slytherin. They taught him how to get away with things, how to start a duel, and what spells should and shouldn't be used. Xavi passed these words down to Valerie, who put her own twist on them.
