Sirius runs into the class. "Sorry professor, I didn't hear my alarm.." Sirius said tying his tie. McGonagall looks at him. "And apparently you changed houses during the night." She said calmly. "What?" He asked confused. "Your tie.." She pointed at his tie. Sirius looks down at his tie and notices that it's a Slytherin one and he slowly takes it off. "I-" Sirius tried to explain but you came in wearing a Gryffindor tie. "Fuck.." He said slightly blushing.
