 What can be inferred about the destination decision at the end of the passsage?
"It is rather unusual," Magnan said, "to assign an officer of your rank to courier duty, but this is an unusual mission." They're called Jorgensen's Worlds, and in themselves are of no importance whatever. However, they lie deep in the sector into which the Soetti have been penetrating. "Now—" Magnan leaned forward and lowered his voice—"we have learned that the Soetti plan a bold step forward. Since they've met no opposition so far in their infiltration of Terrestrial space, they intend to seize Jorgensen's Worlds by force." Magnan leaned back, waiting for Retief's reaction. "This is open aggression, Retief," he said, "in case I haven't made myself clear. "I have here," he said solemnly, "information which will change that picture completely." Magnan spread his fingers, folded one down. "The Soetti War Plan—in detail. Overall policy calls for a defense of these backwater worlds. Otherwise the Corps would allow history to follow its natural course, as always." Your accommodations are clear as far as Aldo Cerise. Retief opened the envelope Magnan handed him and looked at the tickets inside. "You'd better waste no time getting over to Indoctrination," Magnan said. "I'll tell you what," Retief said soberly. "You'll be traveling with Class X credentials," Magnan snapped. "You'd better be getting started," Magnan said, shuffling papers. II Retief put down the heavy travel-battered suitcase and leaned on the counter, studying the schedules chalked on the board under the legend "ALDO CERISE—INTERPLANETARY." "Lifts in an hour. VIP's required accommodation," he said. You'll have to try to get space on the Four-Planet Line ship next—" "Which gate?" "But—" Retief picked up his suitcase and walked away toward the glare sign reading To Gates 16-30 . Retief followed the signs, threaded his way through crowds, found a covered ramp with the number 228 posted over it. The guard crumpled the gram, dropped it on the floor and lounged back against the handrail. He picked up his bag, stepped over the man and went up the gangway into the ship. "Which way to cabin fifty-seven, son?" Retief asked. Retief made his way along the narrow hall, found signs, followed them to cabin fifty-seven.
 Retief will ensure the ship travels to Jorgensen's World, as initially planned
