Parallels

Disclaimer: As you can probably guess I don't own Harry Potter (unfortunately) or anything else from the Harry Potter books. All I own is the plot (apart from the start of chapter 1) and any unfamiliar characters, places or things.

Prelude

After being convinced of Sirius Black's innocence in the Whomping Willow Sirius, Remus, Harry, Ron and Hermione escorted Peter Pettigrew to the castle. When Remus became a werewolf because he had forgotten to take wolfsbane potion Pettigrew managed to escape, injuring Ron in the process. Sirius managed to chase Remus away from the students in his dog animagus form but when he went after him Dementors surrounded him. Harry and Hermione tried to help but their Patronus' were not strong enough. The Dementors were about to administer the Kiss when Snape, who had just woken up cast a Patronus and then took them all to the castle.
