The Captain was on a mission.
He rushed the two of them to the cafeteria and ordered food for delivery, all while chatting to Hill and Gunther in a group call. At the same time, he had his arm around Kellen like a leash. He wasn't going to let him escape, and Kellen could feel everyone's eyes on him.
Most of them were hostile, or sympathetic. It wasn't a great feeling, but the Captain wasn't giving Kellen enough time to stew in it. He was making sure they didn't idle in one place long enough for them to get caught in a conversation. He even breezed past the A Class gym when others had clearly spotted them. They seemed stunned that the Captain had done so, while Kellen just looked at them apologetically.
