Khan had many questions and doubts. He didn't know his role on the battlefield, his team's arrangements, the chain of command, and more. He was unaware of anything connected to his new location. Still, getting answers wasn't an option.
Even as the team began amassing corpses, Khan continued feeling hesitation and distrust toward him. No glares or specific gestures flew in his direction, but the symphony confirmed that he was an outsider.
Lacking intel wasn't ideal, especially after seeing the size of the Thilku battlefield. However, Khan couldn't get accepted through words. He could only prove himself and cause as few problems as possible.
Khan focused on cleaning the battlefields, imitating his alien companions whenever he doubted his actions. The task wasn't exactly difficult. He only had to amass corpses into piles, and looking at the Thilku told him how big they had to be.
