In the book Little Women, in the last chapter there is a little boy sitting next to Amy with crutches...?

Question

Who is this little boy?
Is he one of her nephews? Or is it one of Jo's boys from the school?
The book shows the boy looking up affectionatly at her so I was just wondering whether he was a relation.

Answer 1

This is one of Jo's students at the harvest festival. He has his crutch resting next to him as he looks at Amy who is sketching.
Chapter 47:
"The Professor charged up and down the green aisles like a stout Teutonic knight, with a pole for a lance, leading on the boys, who made a hook and ladder company of themselves, and performed wonders in the way of ground and lofty tumbling. Laurie devoted himself to the little ones, rode his small daughter in a bushel-basket, took Daisy up among the bird's nests, and kept adventurous Rob from breaking his neck. Mrs. March and Meg sat among the apple piles like a pair of Pomonas, sorting the contributions that kept pouring in, while Amy with a beautiful motherly expression in her face sketched the various groups, and watched over one pale lad, who sat adoring her with his little crutch beside him."

Still from Chapter 47 (the last chapter):
"Very precious to Jo was the friendship of the lads, their penitent sniffs and whispers after wrongdoing, their droll or touching little confidences, their pleasant enthusiasms, hopes, and plans, even their misfortunes, for they only endeared them to her all the more. There were slow boys and bashful boys, feeble boys and riotous boys, boys that lisped and boys that stuttered, one or two lame ones, and a merry little quadroon, who could not be taken in elsewhere, but who was welcome to the `Bhaer-garten', though some people predicted that his admission would ruin the school."

Answer 2

I don't remember a boy with crutches in the book. Was this just an illustration or was it in the text?
