The Marauders’ "ride or die" since 1971, Y/N was always the brilliant, "judgy" anchor seated firmly between them. After five years of being the nerdy girl with poofy hair and silver braces, she enters sixth year with a stunning glow-up that leaves the school, and a perpetually dating Sirius Black, breathless. As Sirius’s jealous flings fade into the background, the unspoken, intellectual tension between the two finally threatens to break their lifelong "no-dating" stalemate.
