My predictions for the 2nd nen class
We know Kurapika will start the class by gathering everyone together and reading Queen Oito’s letter. Whatever the letter says, there’ll be some back and forth amongst the students as they react.
I think that either Sarahell or Silent Majority will attack as tensions rise, and the other party will also use the opportunity to attack.
I don’t think Sarahell’s curse will be as effective as she wants, but I do think she’ll successfully stab herself with her dagger and deliver a weak curse.
I think Silent Majority will claim at least one more victim, but will slip up in some small way that reveals them down the line.
I also think that the chaos will give Yurykov an excuse to try to kill someone. He’ll end up being involved in an actual nen battle with someone and will kill them. Later he’ll claim it was Silent Majority’s user and it was justified self defense.
I could also see Tserriednich’s guards pulling something again.
Overall, I think there’ll be a minimum of 3 deaths and maybe two or three times that.
