Khan's statement left no room for discussions. He wasn't giving an opinion or an order. He had said what would happen, and his teammates didn't know how to reply. They remained silent, watching him inspect the main deck.
The ship was a bit too big and complicated for Khan's training, but he recognized most commands. Turning on the pilot's menus and skimming through them gave him a basic rundown of its functions. With enough time to prepare, he could quickly adapt, and the loading state would grant that.
As for the Global Army, those worries never crossed Khan's mind. The regulations might go against him, but no one would dare to step up to stop him. Even his teammates couldn't find the strength or will to refuse him.
Of course, Khan knew his behavior was arrogant and uncompromising. He was almost doing everything in his power to sour the potential relationships with his teammates, going against the purpose of having companions in the first place.
