Looks like the bodyguards are being killed by having all the blood drained out of them. And, oh shit, Kurapika's packing heat! Getting all the bodyguards together to check if the culprit is among them with his Dowsing Chain. "If you lie, this chain will spin. If it spins, I shoot...!" So badass. And I think he's only ever directly killed one person in his life: Uvogin. (Pakunoda's death was more of a suicide).
And this woman, Kaa, plans to kill off all the other Princes, with the help of her friend, Fuu. Senritsu overheard them, so I wonder if she'll take action.
I wonder what Ging and Pariston are doing? Haven't seen them for awhile...
