In Chapter 5, Daniel has gone on a mission to see Joel, hoping that he can recruit Joel to join in Rosh's cause. He meets Joel's father, Hezron, and says things that upset him. He leaves in shame and disappointment, and when he stops along the road for water, he is met by a Roman soldier. The soldier demands Daniel give him a drink, and Daniel, overcome by furious hatred, throws water in the soldier's face. Daniel runs but is struck by a spear. He manages to get away, but he is wounded. He makes his was back to Joel's house and staggers in. Thacia is shocked to see he has returned and scolds him, but he faints in her presence from the trauma of his wound. Joel drags Daniel into a storage area, and they later move him to a passageway between two walls that is hidden from the rest of the house. There Joel and Thacia nurse him back to health without their parents' knowledge, and the three become friends and take a vow together to fight "for God's victory." Daniel leaves without their knowing, but not before they have arranged a way for Daniel to get a message to them in the future.
