Quote #4
MOODY/CROUCH: Only an exceptionally powerful Confundus Charm could've hoodwinked it. Magic way beyond the talents of a fourth year.
KARKAROFF: You seem to have given this a fair bit of thought, Mad-Eye.
MOODY/CROUCH: It was once my job to think as dark wizards do, Karkaroff. Perhaps you remember.
Snap. Moody and Karkaroff used to be on different sides of the good vs. evil equation, and this is a definite dig at Karkaroff's Death Eatery past. Of course, what no one except "Moody" knows is that "Moody" is actually Barty Crouch Jr. in disguise, and he's actually the evil one still doing Voldemort's bidding.
Quote #5
MCGONAGALL: This can't go on, Albus. First the Dark Mark, now this?
DUMBLEDORE: What do you suggest, Minerva?
MCGONAGALL: Put an end to it. Don't let Potter compete.
McGonagall definitely seems to think there's something sinister about Harry's name being in the Goblet of Fire, and she links it to the appearance of the Dark Mark at the Quidditch World Cup. Hmm, we're trying to hope for the best, but…it's kind of hard.
Quote #6
SIRIUS: Look, Harry, the Death Eaters at the World Cup, your name rising from that goblet…these are not just coincidences. Hogwarts isn't safe anymore.
HARRY: What are you saying?
SIRIUS: I'm saying the devils are inside the walls. Igor Karkaroff? He was a Death Eater. And no one—no one—stops being a Death Eater.
Well, if Harry was looking for comfort from his godfather Sirius…he didn't get it. Apparently, the headmaster from Durmstrang used to be a big Voldy fan, and Sirius thinks that Harry's name being in the cup = someone seriously has it in for Harry. Scary stuff.
