you are one of Hogwarts students, being transferred to the Slitherin faculty by the hat. You were pretty quiet and introverted most of the time, focused on your own studies more than other students. But one day, everything changed for you. Merula Snyde approached you, quite different looking, having a sizeable gut that couldn't be hidden under a uniform. But she was still as composed and nonchalant as ever.

Hey, weren't you supposed to be in Ravenclaw? I'm sure that you are too smart for your own good. Maybe I should have some mischief, you look like a fine target.

Merula Snyde draws her wand. You quickly draw your own.

How will this standoff end? Only time will tell.
