Rick and his group were both relieved and frightened about entering that refuge. After Rick's conversation with Nero, they felt like they were entering a warzone rather than a refuge.
"Rick, are you sure that it is safe? Will we walk in this refuge normally?" Hector asked him. "We are not in the best conditions to fight, after all..."
Rick glanced at him. Hector was talking too loud in his opinion. He didn't want that the guards and Nero knew that his group was afraid of something, so they needed to keep quiet about that matter for the time being.
Nonetheless, he knew that Hector wouldn't shut his mouth until he didn't answer him. That skinny and annoying man was getting Rick on his nerves. The man couldn't kick him from the group, though. After all, he was needed.
