I have two questions regarding the game. I read that if you do it right you can get all the blood codes in a single playthrough. At what point is it safe to go back and rescue the heroes, I heard if you do it too early you risk losing some blood codes.

The second question is regarding the Jail's, I know Reaper has a party window but is there any particular one you would say stands above the other?
