There were a few things about Knight which really stuck out to Hisoka, taking a few moments of silence to contemplate the information, ensuring what he was about to say was not utterly mad.

[i]"...A ghoul that owns both a horse and motorcycle and can afford to maintain them to the point of being able to shake pursuit. Properly looking after a horse in this climate can be anything from 170,000 yen upwards a year, and motorcycles are incredibly costly in their own right. We're looking for a person who is relatively comfortable, six foot, and possibly has an interest in Western History given their dedication to the role. Is there a blacksmith in either this District or the neighbouring ones?"[/i]

It was verbal diarrhoea for the most part, but she did ask for his thoughts. Hisoka bit down on his thumb, more ideas coming to mind. It was difficult to know what exact year Knight became active, but a first recorded incident would be enough to work backwards from - enough to create a good assumption. 

[i]"I think we should ambush the ambusher..."[/i] He started, looking up into the eyes of Yuuka. It appeared they were similar in some way, his red orbs carrying a completely different feeling than the kind, if confused, look that was in them before. [i]"If we can start to figure out his identity, then we can catch him unaware in the middle of his cover life. More likely to bring him back in alive, less likely to be ready for a fight."[/i]
