The second time he's had to come to the hospital for a blood sample, zeroichi is all, "I can't breathe in a hospital" . Uh-oh. He's not the only one who's been waiting in the hospital. The commander has told him that gaido is being removed from the nano-machines program, which means that he'll no longer be able to use his blood to keep the machines running. He doesn't want to be the one to do it, he tells zeroichi, because it's his own fault that he got gaido into this mess in the first place. He also says that the nano machines are in a state of starvation, and that's why they're going crazy. If you're the one who needs the blood, he says, you can either use it to replenish your own body with the same kind of blood as he does , or you can use the blood of someone else who needs it. The problem is that, once he loses control of his nano machines, he won't have the ability to keep them running. If he does, it'll be very difficult for him to control them again.
