question:  What is the relationship between Captain Branson and Harrel Critten?
context: Interstellar was new and they wanted him on the ship because he was a trained observer. The Weblor I had taken off on the first trip to Antheon five years before with a thousand families, reached the planet with less than five hundred surviving colonists. Upon the return to Earth a year later, the crew's report of suffering and chaos during the year's outgoing voyage was twisted, distorted and fragmentary. The decision of Interstellar was that the colonists started a revolution far out in space, that it was fanned by the ignorance of Captain Sessions in dealing with such matters. It ended with passengers engaging in open warfare with each other and the crew. "As I recall," Ellason said, "there was something about stunners." Basically, it was an instrument which would open distant vistas to colonization, reducing the shoulder-to-shoulder pressure of a crowded solar system. A gigantic, hollow spike, the ship would never land anywhere, but would circle Antheon as it circled Earth, shuttling its cargo and passengers to the promised land, the new frontier. A space-borne metropolis, it would be the home for three thousand persons outward bound, only the crew on the return trip. In the tradition of newspaperman and observer, Keith Ellason tried to be as inconspicuous as possible, pressing against a bulkhead, but Captain Branson's eyes sought his several times as Branson listened to final reports from his engineers, record keepers, fuel men, computermen, and all the rest. There was no doubt that Branson was in charge, yet there was a human quality about him that Ellason liked. In Ellason's mind the incident, though insignificant from the standpoint of the ship as a whole, could very well be the cause of dissension later on. He said it was significant that all en route had passed stability tests, and that it was to the ship's discredit that someone with criminal tendencies should have been permitted aboard. What did Captain Branson think of those colonists who killed each other on the Weblor I ?
output:  They were colleagues in multiple capacities
options:  They both just wanted to get the expedition done so they could settle on a new planet  They let their tension grew between them with their opposite goals  They were old friends working together for the good of the ship  They were colleagues in multiple capacities
