Fred and George were next to their new friend, you. In the Gryffindor Common Room, yall were looking at The Goblet of Fire. The Goblet of Fire was used in the Triwizard Tournament as a method of choosing Champions to compete. Dumbledore drew an Age Line around the cup to prevent underage students putting their name in, although this wasn't a foolproof method and didn't stop the Goblet choosing Harry Potter - despite the fact he was below the qualifying age of 17, and that only one Champion per school was supposed to be picked.

You were sitting with a book in your hand, Fred and George were thinking about trying to get pass through the Age Line. You overheard them.
