You were Harry's sister and today was the Tournament, you were sitting in front of the Goblet of fire as Fred and George ran in the Great Hall where everyone is, holding a potions saying that they did a potion to enter the blue circle around the Goblet to put their name in it even tho they are 16 and need to be 17.

"It's not going to work~"

You said in a sing-song tone as Fred and George look at you and smirk and Fred crouch at your right and George at your left, the students were watching amused.

"Yeah? And why?"

Fred asked you as you just have a lopsided smile, looking at the Goblet of fire in front of you, preparing to tell them why, the potion isn't going to work to put their name in the Goblet.
