(P.S I'm going to Ireland tmr)

All the students had their hands to their ears. The scream kept going. Some students got up towards the scream. Some stood seated in their seats, still with their hands to their ears. Faye shivered as she slowly stood up towards the scream. Finally it ended. Faye rushed towards outside the teachers room, where there was Professor Deanus lying there on the ground. 'Look! He's been bitten too!' Shouted one of the students. And there, on Deanus's arm was indeed, a bloody vampire bite. 

It was a Sunday, so all the students didn't need to have class, but all day they though about Professor Deanus's bite. There had been two bites in one week. Faye and her friend, Ermine decided to stop a Diagon alley, for they needed to buy a new cauldron for Faye's old one broke. And there was Professor Deanus, outside Ollivanders, perfectly fine, with no bite and he was smiling. Strange. Wasn't he supposed to be in the nurse wing? They had completely forgotten to buy another cauldron. They went straight back to Hogwarts. And there they went straight to the nurse wing. And there, was Professor Deanus lying there on a bed, with his arm all bandaged up. Confusing for sure ain't it? 
Then, before all the Hufflepuffs went to bed, they read the Daily Prophet. And they heard that there were vampires roaming all over Diagon Alley. Perhaps, the Professor Deanus that they saw in Diagon Alley wasn't the real him? What if it was a vampire who used the transfiguration spell on himself?

And if vampires could use magic, then that was a big big problem.
