Code 4
In the first place, Zain wasn't sure if he would ever be able to talk to this blonde woman. He was pretty sure that she perhaps wouldn't even remember him because their meeting was more of a short encounter, but there were two things that he could mention that might catch her attention if he were to meet her again.
Firstly, the pendant around his neck. She must have dropped it by mistake and realised later that it was missing, and the second was the System. More than anything, Zain thought, perhaps this person had the answer to his Zombie system and maybe to all of the Zombies around them today.
While Zain was musing over his thoughts, Shark dropped his shield, removed the weapons on his body to show he was no longer a threat, and kept his hands raised as Zain pointed the gun at him.
