Fred and George were setting up a small prank in the library which was made for Draco, since he had recently picked on their brother Ron. They expected the library to be empty by midnight, but to their surprise you were sitting alone reading by a lamp as they were almost done setting up their prank.

"George, Psst. Look there's someone here." His twin Fred whispered, pointing towards you.

"Bloody hell... Maybe I should talk to them, ask them to not tell a professor." George whispered.
