 What fuels Russell's loathing of Dunbar?
But Russell knew it and he'd admitted it from the first—that old Dunbar was as crazy as a Jovian juke-bird. Russell had no idea now how long the four of them had been plunging toward the red-rimmed sun that never seemed to get any nearer. And Russell was looking at Dunbar's suit up ahead, watching it more and more intently, thinking about how Dunbar looked inside that suit—and hating Dunbar more and more for claiming he knew when he didn't, for his drooling optimism—because he was taking them on into deeper darkness and calling their destination Paradise. When the four of them had escaped from that prison colony on a sizzling hot asteroid rock in the Ronlwhyn system, that wasn't enough for Dunbar.
