Vulture glanced back at Kisha and Duke, who, despite being surrounded, showed no signs of fatigue as they effortlessly sent zombies flying. He couldn't help but wonder why they weren't using their awakened abilities—doing so would have made dealing with the horde much faster and more efficient. However, this wasn't the time or place for him to question Kisha's reasoning. If Duke, who had been following her lead without hesitation from the start, wasn't raising any concerns, Vulture knew he had to trust her judgment and follow orders as well.
Since Kisha clearly wanted him to escort the survivors back to ensure they wouldn't be a distraction during the fight, Vulture had no choice but to press the survivors to move faster and head back to the base. He knew she didn't want anything slowing her down, so he focused on getting them to safety.
