NEEDLESS/Headscratchers

• Why exactly was Cruz left behind when Blade and co. decided to go to the city? To date he's been one of the most valuable members of the group and several times has been the reason that they survived a fight.
  • Explained in Chapter 99
• Prior to the events of the manga, if the leader of the resistance group knew that the information was suspect and that Aruka was probably a traitor then why did he go along with it? What was stopping him from quietly telling a few of the his subordinates the truth?
• Why did the leader of the resistance give Cruz the information? If he was expecting to die and wanted to keep it out of Aruka's why didn't he just smash it? He couldn't have expected Cruz to have any use for it.
