Harry tells Ron and Hermione about the attack on Viktor and the disappearance of Mr. Crouch.
He concludes: "I've told you [...] He said [Voldemort's] getting stronger" (29.14).
Harry goes to send all of this information to Sirius.
He, Ron, and Hermione bump into Fred and George in the Owlery.
Fred and George are arguing over whether they should blackmail someone.
But they still won't tell Ron what's going on.
Ron is worried that Fred and George will get in trouble with the law. After all, "they don't exactly mind breaking rules, do they?" (29.59).
Harry, Hermione, and Ron see Professor Moody.
Professor Moody has found no sign of Mr. Crouch.
Professor Moody reminds Harry, "Constant vigilance" (29.90).
He also tells Ron and Hermione to "stick close to Potter, all right?" (29.91).
Sirius's letter is stern: "Your name didn't get into the Goblet of Fire by accident. If someone's trying to attack you, they're on their last chance" (29.92).
Sirius suggests that Ron and Hermione help Harry learn some more hexes for the third task.
So Harry stays inside and practices spells.
One day in Divination, Harry begins to drift off.
Suddenly, he sees a vision of Voldemort plotting with Wormtail.
Voldemort casts the Cruciatus Curse on Wormtail for blundering.
