The Problem: Signs and portents suggest that Voldemort is marshalling his forces. And Harry must face his first school dance.
Quidditch Update: Harry attends the Quidditch World Cup (Ireland Wins)
Scary Monster: The Hungarian Horntail, a particularly nasty breed dragon.
Magical gadget: Portkeys, everyday objects that instantly teleport wizards who touch them.
Defence Against the Dark Arts: Mad-Eye Moody � scarred, wooden legged and generally scary looking. But his secret identity is even scarier.
New Spell: The Imperius Curse. Basically, magical mind control. Few people can resist its power, but Harry of one of them.
What Harry Learns: Doing the right thing usually means doing the hardest thing. Plus, girls are complicated.
Mistakes:
During Priori Incantatem, Voldemort's victims came out in reverse order. BUT, James came out BEFORE Lily. That would mean that James died AFTER he killed Lily and it said all over in the books that he killed James first.
After Hermione dropped Muggle Studies, she said she had the same amount of subjects as Ron and Harry. But she still had (besides the mandatory ones) Arithmancy, Care of Magical Creatures, and Ancient Runes.
When Dumbledore was telling everybody about the Triwizard Tournament during the start of term speech he said: "We have worked hard over the summer to ensure that this time, no champion will find himself or herself in mortal danger." (Do you think facing a Hungarian Horntail that breathes fire forty feet would classify as 'mortal danger'? Even if there were trained hit wizards nearby you catch one of those flame-bursts and you�re a corpse before the wizards can do anything.)
It said she brings out a 3-legged chair with the sorting hat. What happened to one of the legs?"
