Final answer:
John Holbrook reveals to Kit that he is pursuing a career in medicine in "The Witch of Blackbird Pond."
Step-by-step explanation:
In The Witch of Blackbird Pond by Elizabeth George Speare, John Holbrook is an intelligent, attractive man with great social skills. He seems capable of taking the world by storm if only he will form an opinion and speak up. John Holbrook is the son of a tanner who taught himself Latin by candlelight. Unable to afford tuition at college, he has traveled to Wethersfield to study with the Dr. Reverend Bulkeley. He arrives in Wethersfield at the same time as Kit.
In "The Witch of Blackbird Pond," upon meeting John Holbrook on the road, he reveals important information to Kit. He tells her that he is pursuing a career in medicine, indicating his aspirations and the reason for his scholarly pursuits. This revelation underlines one of his personal goals and illustrates his studious character, distinct from being either a spy for the English government or a fugitive from the law.
