I was thinking they were ready to spend the rest of their days there without coming out Malachi thought when he saw the four new arrivals on the first floor of the store.
Apart from the family of three on the second floor, trapped inside because of the zombies, there was also another group of four trapped in the basement, and the four new arrivals in the store were those four.
Two females and two males.
The first floor of the store was relatively lit now that everyone had a flashlight. Thankfully, all flashlights were set to the lowest. Perhaps they followed David's example if they were wise to think more. Because of the now better-lit floor, Malachi was able to see the appearance of the four individuals well.
The floor was all dressed in the same clothing, and looking at the appearance of the attire they wore, it was easy to figure out that they were employees of this store.
