Jonner. Jonner was still in the same place, sitting down. Kraag heated breakfast and ate it with an eye on the port. Jonner didn't move. Kraag felt better when he had eaten, and went up to the control room. "Why don't you give it up and come on in, Jonner?" he asked. "The oxygen in that suit's not good for more than another 15 hours." "That's where you're wrong, Kraag, and that's what's so tragic about your murdering Stein," said Jonner quietly. "You either forgot that we carried oxygen instead of nitric acid as the fuel oxidizer this trip or, being an engineer, you didn't think of it except as fuel. "There's enough oxygen in the tanks scattered over the landscape to keep a dozen men alive until the rescue ship gets here. It's hard for me to get at, but I've already found I can manage it." Kraag was profoundly shocked. For a moment the enormity of what he had done in killing Stein almost overwhelmed him. It had been completely unnecessary. Then his self-reproach turned into a growing anger against Jonner. Jonner was always so reticent, always required his orders to be obeyed without explanation. During the whole argument about taking an orbit around the asteroid, during the whole time it had taken to spiral down to a crash, he had not told Kraag how he expected them to stay alive until they were rescued. Kraag hadn't asked him, of course. Kraag had assumed Jonner was thinking in terms of his own figures. "I'm sorry about Stein," said Kraag, and meant it. "But it can't be helped now, Jonner. There's enough air for both of us, if you'll keep your mouth shut when the rescue ship gets here." "If I promised, I still wouldn't trust you and you wouldn't trust me. No, Kraag. The only way it'll work is for you to come out unarmed and let me go in and get the guns. Then I'll lock you in the control room till the rescue ship gets here." "One of us is a fool, Jonner, and you seem to think it's me. I'm not going to burn for murder. I've got the whip hand. You may have oxygen, but you've got to have food and water, too." Jonner laughed, without humor. "I've got enough of that for three Earth days and I can last longer," he said. "Before that time, I'll come and get you, Kraag. Don't go to sleep!"
