I tried to explain this scene to a friend the other day, but did a terrible job of it. Time to let the words speak for themselves:
"Freddie: No. I’m a good boy. When I’m told to go—I go. (He fumbles in his pockets. To Miller) Can you lend me a shilling?
(He tosses the coin on to the table L of the door up C) Just in case I’m late for dinner.”
