 Of his fellow crew members, who does David seem to have the most concern for and why?
CAPTAIN CHAOS By D. ALLEN MORRISSEY Science equipped David Corbin with borrowed time; sent him winging out in a state of suspension to future centuries ... to a dark blue world whose only defense was to seal tight the prying minds of foolish interlopers. "Your name is David Corbin. "Your name is David Corbin. The mesh-covered hole and the two lights looked like a caricature of a face, set in a panel of dials. How do you describe being weightless when you are born into a world bound by gravity. There was no sensation of place, no feeling of up or down, no direction. "Your name is David Corbin." After the first shock of looking out, I accepted the fact that I was in a space ship, yet I couldn't read the maps that were fastened to a table, nor understand the function or design of the compact machinery. Now it must tell me why I didn't. "Your name is David Corbin. It was the only thing I saw that could help me, guard me against another shock like seeing outside of the clear portholes.

 Karen, because she's a female crew member and because she has a bad reaction to being awoken.  John, because he relies on him to be his right-hand man.  John, because David first wakes him up with the apparatus and is unsure how safe the apparatus is to operate.  Karen, because she's his wife and he only remembers this with time.
