[History of Magic] crawls along, with even Hermione avoiding taking notes, for the first time in memory.

A Busy Owlery
In the morning, Harry, Ron, and Hermione stand in the [Owlery] wondering what happened to [Crouch] and [Krum], and what Crouch's rants all meant.
Hermione tells Harry and Ron to freeze, as they hear someone coming - but it turns out to be Fred and George, talking on the way up about blackmailing someone. When Ron confronts them about it, though, they shove him away and walk off, leaving the trio wondering what they're up to.
After class, Harry, Ron and Hermione race to find Moody, and ask him whether he managed to find [Barty Crouch]. To their disappointment, he says that he didn't, and asks Harry to be focusing instead on the upcoming [third task].
Sirius writes back to Harry, chastizing him for walking off on the grounds with [Viktor Krum]. Hermione finally reasons with him as well, and convinces Harry to stay indoors until the [third task].
During a free moment in the [Charms] classroom, Harry practices [Stunning Spells] on Ron and Hermione. They then decide to move on to [hexes] next, but the bell rings and Harry and Ron grudgingly make their way up to [Divination].
A Disturbing Dream in Divination
In [Divination], Harry falls asleep and has a [dream] - or perhaps a vision - that Voldemort is torturing Wormtail.
Harry is awakened by Ron and Trelawney, the latter of whom seems overly excited about his falling on the floor screaming and clutching his [scar]. Instead he tells her he's heading for the [hospital wing], and sets off out of class.
Rushing out of [Divination], Harry heads not for the [hospital wing] but for [Dumbledore's office]. He manages to guess the correct [password], "[Cockroach Cluster]," and heads inside.
Partially into [Dumbledore's office], Harry overhears [Dumbledore] and Fudge arguing over what happened to [Barty Crouch] and [Viktor Krum]. Fudge seems prejudiced to think that [Madame Maxime] might have been to blame, but won't be swayed by Dumbledore's logic. They are soon stopped, though, when Moody notices that Harry is outside the door.
