I'm thinking about an Unforgivable Curse. It had the shortest incantation, and it was often used as punishment in the 1997-1998 school term... Yeah. Cruciatus Curse.
No idea but I amor that moment, that reply. We can already see that Neville is going to play an important part in the rebellion inside Hogwarts. He said that only but there's so much in one single reply.
Now, every time I use "losers", I can't help thinking about Neville and that short yet powerful scene.
Maybe Cruciatus? I mean they don't let anybody go with calling them "loosers" now, do they?, unless its Lucius. He is really patient. Yep! the only possibility is cruciatus!
I dont think they went as sirius (haha get it) as to go crucio on him, but i do think they may have punched him in the face or the gut. Though after he said that line, i was WHOO!! GO NEVILLE!! PWNED! haha i loved that part, you can see he's already changed, and that hes gonna be big in the battle of Hogwarts
Well, I think the Death Eaters didn't want to stir any trouble up on the train, so they probably like growled or something and went on their merry ways.
