Somewhere around the second day he became obsessed with the thought of himself as brain-transplant bait for Miles. Oddly enough, or perhaps logically enough, he did not fear it from Miles. But Miles was hardly in a position to veto the plan. What if it occurred to someone that it would be easier to transplant Miles's brain into Mark's warm and living body than to attempt the tedious repair of that gaping mortal chest wound, and all the cryo-trauma on top of it? It was so frightening a possibility that he half-wanted to volunteer, just to get it over with.

The only thing that kept him from total gibbering breakdown was the reflection that with the cryo-chamber lost, the threat was moot. Until it was found again. In the dark of his cabin, his head buried in his pillow, it came to him that the face he'd most desired to see transformed with respect for him by his daring clone-rescue was Miles's.

You've rather eliminated that possibility, haven't you? 

The only surcease from his mental treadmill came with food, and sleep. Forcing down an entire field-ration tray left him blood-stunned enough to actually doze, in inadequate snatches. Desiring unconsciousness above all things, he cajoled the glowering Dendarii who shoved the trays through his door three times a day to bring him extras. Since the Dendarii apparently did not regard their disposable-container field rations as treats, they were willing enough to do so.

Another Dendarii brought, and shoved through the door, a selection of Miles's clean clothing from the stores on the Ariel. This time all the insignia were carefully removed. On the third day he gave up even attempting to fasten Naismith's uniform trousers, and switched to loose ship knits. At this point the inspiration struck him.

They can't make me play Miles if I don't look like Miles. 

After that, things grew a little foggy, in his head. One of the Dendarii became so irritated by his repeated requests for extra rations that he lugged in a whole case, dumped it in a corner, and told Mark roughly not to pester him again. Mark was left alone with his self-rescue and cunning calculation. He had heard of prisoners tunneling out of their cells with a spoon; might not he?

Still, loony as it was, and on some level he knew that it was, it gave his life a focus. From too much time, endless hours on the multi-jump boost through to Komarr, suddenly there seemed to be not enough. He read the nutrition labels. If he maintained maximum inactivity, a single tray provided all the daily fuel he required. Everything he consumed after that must be converted directly into Not-Miles. Every four trays ought to produce a kilo of extra body mass, if he had the numbers right. Too bad they were all the same menu. . . .
