Is Doodle a round or flat character in "The Scarlet Ibis"?

A round character is a character that displays several different character traits. Often, these types of characters are considered to be well-developed, multidimensional, and realistic. Doodle is a round character. He is more than a stereotypical annoying little brother. That would be a flat character. Despite his handicap, Doodle is smart, imaginative, caring, and loving. We see his imaginative side when Brother tells us that Doodle made up "crazy" stories about winged people. Readers get to see his joy and sensitivity about life's beautiful things when he sees the swamp:

His eyes were round with wonder as he gazed about him, and his little hands began to stroke the rubber grass. Then he began to cry. . . . "It's so pretty," he said. "So pretty, pretty, pretty."

We also get to see Doodle express fear when he is worried that his older brother is going to leave him behind in the barn loft. Finally, we also know that Doodle looks up to his brother and is fearful about disappointing his idol. Doodle is a well-developed and round character, and that is precisely why it is so maddening that Doodle dies in the end.
