 What was the author's purpose on including a section about Hatcher's feedings?
THE FIVE HELLS OF ORION BY FREDERICK POHL Out in the great gas cloud of the Orion Nebula McCray found an ally—and a foe! [Transcriber's Note: This etext was produced from Worlds of If Science Fiction, January 1963. Extensive research did not uncover any evidence that the U.S. copyright on this publication was renewed.] Whatever it was, he had no business in it; for five minutes before he had been spaceborne, on the Long Jump from Earth to the thriving colonies circling Betelgeuse Nine. McCray was ship's navigator, plotting course corrections—not that there were any, ever; but the reason there were none was that the check-sightings were made every hour of the long flight. He had read off the azimuth angles from the computer sights, automatically locked on their beacon stars, and found them correct; then out of long habit confirmed the locking mechanism visually. And while he was looking at Betelgeuse, Rigel and Saiph ... it happened. There simply was no way for him to get from a warm, bright navigator's cubicle on Starship Jodrell Bank to this damned, dark, dismal hole of a place where everything was out to hurt him and nothing explained what was going on. well, it was an explanation with more holes than fabric, like a fisherman's net, but at least it was rational. How to explain a set of Gibbon's Decline and Fall of the Roman Empire? Or the old-fashioned child's rocking-chair, the chemistry set—or, most of all, the scrap of gaily printed fabric that, when he picked it up, turned out to be a girl's scanty bathing suit? Even the child's chair—why, he'd had one more or less like that himself, long before he was old enough to go to school. Areas in it had the appearance of gratings; from them issued the pungent, distasteful halogen odor. Item, a short time ago—subjectively it seemed to be minutes—he had been aboard the Jodrell Bank with nothing more on his mind than completing his check-sighting and meeting one of the female passengers for coffee. Item, wherever he was now, it became, not so much what had happened to him, but what had happened to the ship? He pressed the unsealing tabs, slipped his hand into the vacant chest of the suit and pulled out the hand mike.
 To further elaborate how different Hatcher and his kind are from a human.
 To give insight on Hatcher's personality.  To show that McCray will have to feed like Hatcher if he does not return to Jodrell Bank because there is no human food where he is.  To further elaborate how different Hatcher and his kind are from a human.  To show how grotesque his feeding process is.
