When did Miles Hendon show he was willing to take risks for others in The Prince and the Pauper?

After Edward, the true prince, is expelled from the palace, he manages to escape from Tom Canty but is at loose ends on his own in the streets. While Edward is trying to talk his way into the Guildhall, Miles Hendon encounters the boy and decides to help him. His first risk comes when John Canty appears and tries to abduct Edward, but Miles wards off his attack. He takes the boy home and treats him kindly.
When Edward is lured away, Miles decides on another risky course: to follow and rescue him. After Edward has a number of adventures, he ends up the captive of a mad hermit and will apparently soon be killed. Miles arrives in the nick of time but does not manage to rescue him. Edward is kidnapped once more and, falsely accused of robbery, is about to be attacked. Here Miles makes a decisive, risky move—he jumps in waving his sword around and frees Edward.
