In Harper Lee's novel, To Kill a Mockingbird, there are several instances when Scout and Jem (Atticus Finch's children) show courage, shown in the following quotes.
Chapter One - Jem answers Dill's dare to touch the Radley house.
[Dill said...], "I won't sa you ran out on a dare an' I'll swap you The Gray Ghost if you just go up and touch the house."
...Then I sneered at him.
Jem threw open the gate and sped to the side of the house, slapped it with his palm and ran back past us...
Chapter Four - Jem wickedly propels Scout, tucked inside the tire, into the Radley's yard.
I got to my feet, trembling as I thawed.
'Get the tire!' Jem hollered. 'Bring it with you! Ain't you got any sense at all?'
When I was able to navigate, I ran back to them as fast as my shaking knees would carry me.
'Why didn't you bring it?' Jem yelled
'Why don't you get it' I screamed.
Jem was silent.
'Go on, it ain't far inside the gate. Why, you even touched the house once, remember?'
Jem looked at me furiously, could not decline, ran down the sidewark, treaded water at the gate, then dashed in and retrieved the tire.
'See there?' Jem was scowling triumphantly. 'Nothing to it.'
Chapter Nine - Scout isn't afraid to take on her cousin Francis when he insults Atticus.
Francis said he reckoned I got told, for me to just sit there and leave him alone.
'I ain't bother' you,' I said.
Francis looked at me carefully, concluded that I had been sufficiently subdued, and crooned softly...This time, I split my knuckle to the bone on his front teeth. My left impaired, I sailed in with my right...'
Chapter Fifteen - Scout takes on the lynch mob when one of the men gets rough with Jem.
'Son, I said go home.'
Jem shook his head.
'I'll send him home,' a burly man said, and grabbed Jem roughly by the collar. He yanked Jem nearly off his feet.
'Don't you touch him!' I kicked the man swiftly. Barefooted, I was surprised to see him fall back in real pain. I intended to kick his shin, but aimed too high.
In each of the examples above, Jem and Scout prove their courage, sometimes in the face of real fear, and other times when they act before they have the chance to be afraid.
