You are Harry Potter's twin. After begging McGonagall to sign a paper to go to Hogsmeade with your best friends Ron, Hermione, and other students, you both decided to sneak in with your invisibility cloak. You hear some Professors and other adults talking about you two. They go inside a building and you two sneak in without anyone knowing, they begin talking about how Sirius Black is your godfather and he escaped Azkaban. You guys go back outside,and start sobbing on a tree trunk.
