That evening, many of the occupants of Hogwarts who were not in the DA were surprised to see quite a few students staring down at blank sheets of paper and then getting up and walking purposefully out of the room.

For a while, wild rumours went round, some not really related… McGonagall was actually Cornelius Fudge in disguise… there was going to be yet another Triwizard tournament, and the ones with the pieces of paper were being invited to try to compete in it… the Hogwarts umbrellas were to be turned green and silver by Martin Lewis of Slytherin… the pieces of paper were talking to the students…

Finally, a rumour came round that nudged all the others related to the piece of paper scandal out (the one about Fudge/McGonagall remained firmly in circulation for the rest of the term). Someone had given out these sheets of paper as a sort of challenge, to see if anyone could uncover the message in them. It would be advisable not to ask anyone about where to find one, as this was seen as cheating by the inventor of the challenge and she had therefore charmed the paper to turn the person asking into a small, pink rubber duck (this was actually proven by Martin Lewis of Slytherin, 9th April, 14:00, in second aisle of the library).

So it all faded into old Hogwarts history, and anyone seen with the pieces of paper got the odd respectful nod from passers by.

"Mine says it's called Arnold." announced Herbert Bell to the DA.

"Mine's called Eliza." said Ginny Weasley, looking down at hers thoughtfully. "She's really useful, actually, not just for the Rota, either. She tells me if I've got homework that's due in for tomorrow to all the really nasty professors… you know, professors like Snape and McGonnagall."

There was a general nodding, and Martin McGorthy came forward, "Adam will tell me where I've left something if I ask him to."

"Mine too!" Said Felicity Sickle, "I found out when I was looking for poor Martin Lewis. Dropped him in a puddle by accident on the way to Herbology."

There was a quiet snigger from most of the occupants of the room, all apart from Martin Lewis, who was strangely silent.

"Who did the Rotas anyway?" asked Ginny Weasley. "Does anyone know?"

Everyone shook their heads. Then Colin Creevey piped up from a large, cushy, pink armchair in the corner. "Has anyone thought to ask the Rotas?"
