First ron and lupin came out with pettigrew chained to them, then Hermione, then harry and Sirius, snape floating behind them.

Harry was overjoyed by the thought of living with Sirius, he couldn't wait till the school year was up and he could move in! Suddenly Lupin was howling in pain and his fingers and toes were growing longer, hair started growing all over and a snout grew right on his nose and his ears started to grow and turn pointed. The howl of pain turned into a howl of some other sort.

"HARRY, RUN" He heard sirius yell next to him. Harry took the advice. He started running in the opposite direction, and even though he knew he could not out-run a werewolf, he tried, pumping his legs and breathing harshly.

But before he knew it, fangs were driven into his flesh like a hundred small daggers. He screamed in pain and tried to wrestle free, but that just made the werewolf's jaws shut tighter.

He heard barking from somewhere and Lupin released him only to look at a great black shaggy dog barking and growling. Lupin started to chase after him instead. He heard a dog squeal in pain, but put no mind to it, he was trying and failing to stop the bleeding from his arm. Everything was getting darker and suddenly he couldn't feel or see a thing and he passed out.
