How does Rab's treatment of Johnny help him gain confidence again?

After Johnny is arrested, Rab comes to visit him. He brings blankets and books. Johnny notices that Rab is wearing a medal of the Sons of Liberty. The Sons of Liberty are a group of young men who use force and riots to rebel against the British government and to intimidate Tory figures. Because the prison guards are also Sons of Liberty, Rab is able to get Johnny transferred to a better cell. Since Johnny showed Cilla the cup before the date Mr. Lyte says it was stolen, he will be found innocent if Cilla testifies at his trial.
