Weasley was not a strange name in Hogwarts, as the family was quite large and had a lot of members that had sat on the desks of the school. But no one was prepared for a double trouble that changed everything, literally. With exploding toilets, dungbombs and other pranks, it was inevitable that sooner or later the twins would earn a detention, on which they managed to nick the Marauders Map.

Olive did not walk in Hogwarts to cause trouble or put trouble on her shoulders. Her only mistake was that her name was the first the twins saw on the map. So they chose her as their first priority for their pranks.
And when things start to get out of hand, Olive is dead set on giving Fred Weasley her revenge. To make the matter more difficult than it is, she has to find a partner in crime.

"Say again, why would I help you if you wish to prank my brother?"
"Because that would make you ten galleons richer than him."
