"Expecto Patronum!" I said, waving my wand once more, still not even a tiny bit of silver floated out of my wand. I sat it down back on my desk and turned to the girls. The whole room was filled of people shouted 'Expecto Patronum' and the roof was slowely covered with silver, that had failed to dissapear.
"Hmm, have you been practising Granger?" Tonks said walking past.
"Yea" I said dully "But Stevie's at St Mungo's, it's a little hard to concetrate on good memories."
"Yes, afraid it is" Tonks said nervously "Oh no, Miss Goyle please don't do that!" She stalked across the room to Harriet, who had been shooting her Patronum dust at Jason's eyes.
"Still, no one's even managed to get even a basic shield, this is harder then I thought" I said, picking up my wand again. I looked over at B, I hadn't even seen her try yet "Go on, give it a go B!"
