Paresi said, "We'll tell them something if we _don't_ answer." The Captain set his jaw. "We do what we can, Nick. We do the best we can. Got any better ideas?" Paresi shrugged easily and smiled. "Just knocking, skipper. Knock everything. Then what's hollow, you know about." "I should know better than to jump salty with you," said the Captain, all but returning the doctor's smile. "Johnny. Hoskins. Prepare for exploratory patrol." "I'll go," said Paresi. "Johnny goes," said the Captain bluntly, "because it's his first trip, and because if he isn't given something to do he'll bust his adrenals. Hoskins goes, because of all of us, the Engineer is most expendable. Ives stays because we need hair-trigger communications. I stay to correlate what goes on outside with what goes on inside. You stay because if anything goes wrong I'd rather have you fixing the men up than find myself trying to fix you up." He squinted at Paresi. "Does that knock solid?" "Solid." "Testing, Johnny," Ives said into a microphone. Johnny's duplicated voice, from the open face-plate of his helmet and from the intercom speaker, said, "I hear you fine." "Testing, Hoskins." "If I'd never seen you," said the speaker softly, "I'd think you were right here in the suit with me." Hoskins' helmet was obviously buttoned up. The two men came shuffling into the cabin, looking like gleaming ghosts in their chameleon-suits, which repeated the color of the walls. "Someday," growled Johnny, "there'll be a type suit where you can scratch your--" "Scratch when you get back," said the Captain. "Now hear this. Johnny, you can move fastest. You go out first. Wait in the airlock for thirty seconds after the outer port opens. When Ives gives you the beep, jump out, run around the bows and plant your back against the hull directly opposite the port. Hold your blaster at the ready, aimed down--you hear me? _Down_, so that any observer will know you're armed but not attacking. Hoskins, you'll be in the lock with the outer port open by that time. When Johnny gives the all clear, you'll jump out and put your back against the hull by the port. Then you'll both stay where you are until you get further orders. Is that clear?" "Aye." "Yup." "You're covered adequately from the ship. Don't fire without orders. There's nothing you can get with a blaster that we can't get first with a projector--unless it happens to be within ten meters of the hull and we can't depress to it. Even then, describe it first and await orders to fire except in really extreme emergency. A single shot at the wrong time could set us back a thousand years with this planet. Remember that this ship isn't called _Killer_ or _Warrior_ or even _Hero_. It's the Earth Ship _Ambassador_. Go to it, and good luck." Hoskins stepped back and waved Johnny past him. "After you, Jets."
