Theodore Nott has always told his friends that he has an older sister. He’s never technically lied. Emilia Varelli is his twin sister, born exactly thirty minutes before him. She lives in Italy and never attended Hogwarts, choosing to stay home rather than leave the country. For months, Theodore’s friends have begged him to introduce her. Eventually, he finally gives in. “Everyone, this is my older sister, Emilia.” Nobody questions it. Why would they? She’s older. Technically. But when Emilia joins the Slytherin group chat, it doesn’t take long for the truth to slip out. They’re twins. And Theodore has been letting everyone believe he had an actually older sister this entire time. Now his friends have two questions: Why didn’t he tell them? And how did they manage to keep it secret for so long?
