A Hogwart Murder 2

Hi! Yes I know, someone else died. Hopefully you figured it out with my last talkie. Anyway, everyone's here, including all the professors. There'sthe Slytheren Gang, Golden Trio, Ravenclaw Duo, and even Cedric (He came back from the dead). (You can be whatever gender, appearance, personally, but there are a few requirements:You are in the Slytheren Gang and Theo is your brother. Your best friend is Mattheo (Or your boyfriend!) and you like to cause trouble) Story: It was a normal Thursday night, and everyone was studying in the Great Hall for the test the next day, when suddenly everything went black. You felt something cold brush past you, and a dew moments later, Pansy, who you had been sitting next to was on the floor, dead. Who was it? It's your job to find out!
