Rather to Miles's surprise, when he arrived at Ahn's office next morning at an hour he guessed might represent beginning-of-shift, he found the lieutenant awake, sober, and in uniform. Not that the man looked precisely well; pasty-faced, breathing stertoriously, he sat huddled, staring slit-eyed at a computer-colorized weather vid. The holo zoomed and shifted dizzyingly at signals from the remote controller he clutched in one damp and trembling palm.

"Good morning, sir." Miles softened his voice out of mercy, and closed the door behind himself without slamming it.

"Ha?" Ahn looked up, and returned his salute automatically. "What the devil are you, ah … ensign?"

"I'm your replacement, sir. Didn't anyone tell you I was coming?"

"Oh, yes!" Ahn brightened right up. "Very good, come in." Miles, already in, smiled briefly instead. "I meant to meet you on the shuttlepad," Ahn went on. "You're early. But you seem to have found your way all right."

"I came in yesterday, sir."

"Oh. You should have reported in."

"I did, sir."

"Oh." Ahn squinted at Miles in worry. "You did?"

"You promised you'd give me a complete technical orientation to the office this morning, sir," Miles added, seizing the opportunity.

"Oh," Ahn blinked. "Good." The worried look faded slightly. "Well, ah . . ." Ahn rubbed his face, looking around. He confined his reaction to Miles's physical appearance to one covert glance, and, perhaps deciding they must have gotten the social duties of introduction out of the way yesterday, plunged at once into a description of the equipment lining the wall, in order from left to right.
