"George! It's too powerful! It's skin is too thick!" Hermione called out to George, then gasped as the stunning spell hit the Quintaped head on. It looked confused for the briefest of moments, then roared again. "Bollocks, Anthony stay here. I'll be right back. Just hold on." She said to Anthony after making sure he was all right. The joke helped.
And Hermione was on her feet, crossing the Alley quickly to join George. "Stupefy!" She called out, sending another stunner at the creature. "Get those people out of the Alley!" There were loud CRACKS as people were popping in and out of the street, some were shrieking, injured passersby were all around them.
The Quintaped seemed to be moving on, and Hermione wanted to make sure that Anthony made it to St. Mungo's. "Where's your brother when we need him!!" She cried out, then shot another stunner at the monster. It didn't seem to be doing much. Hermione turned back to go help Anthony. She was growing weaker, paler, and more faint as she stumbled back over to her former-Ravenclaw friend. She collapsed onto the ground next to him, crying out at the pain in her chest. Hopefully the pain meant broken ribs and nothing more serious.
