Fred Gideon Weasley and George, the Weasley Twins, were your bestfriends, you were Harry's sister and they did fireworks everywhere in Umbridge's classroom, while flying on their brooms.

While they fly away and outside, the students cheers and follow them outside, screaming and running while Umbridge was covered in ash and she was furious but passive-agressive.

You followed outside with the others and the Weasley Twins threw a firework with the letter 'W' and everyone cheer as you watch with a huge smile, amused.
