Infected?

Theodore and the others were taken to a place on the mall's second floor; they wanted to see the current condition of the injured person. Theodore had told Roderick to be careful because there was a possibility that the person was infected with the zombie virus. 

"I just want to make sure that the person is injured because of zombies." Theodore finally asked one of the people there. 

"Of course not! We wouldn't allow a zombie-infected person to hide here either," a man who seemed to be the group leader said confidently. 

Even though they said that Theodore wouldn't believe them because they couldn't be missed. 

Theodore remained silent after that and followed them to show them where the injured person was. When he got there, Theodore realized that these people were smart enough to change the furniture in the mall to fit their hospital room. 

Roderick also approached someone by his side who was in charge of medicine in their group.
