Jon stops dead when he hears the man's voice. His gaze moves towards the other guy, noticing him for the first time. A look of awe showed on his face when the zombies seemed to listen to the man's order. He kept the machete up, just in case, and eyed the other's weapon. It was a small gun that wasn't familiar to Jon. Then he takes a quick glance to the girl on the building, wondering if they were some sort of allies.

Jon frowned and turned his attention back to the man and raised up his free arm to signal him not to shoot.

"I'm only helping," he muttered calmly, though he felt more confused now as the zombies stopped attacking.
