Most fans will probably remember Justin Finch-Fletchley (Randell) as the boy who mistakenly believed that Harry tried to sic a snake on him in “Harry Potter and the Chamber of Secrets.” Thanks to his Muggle background, Justin was a prime candidate to be a victim of the Heir of Slytherin. In the novel, after being cured of his petrification, Justin formally shook Harry’s hand and apologized for the misunderstanding.
When we first meet Justin in the books, he is a friendly, agreeable young man who gets along fine with Harry and his friends. We can forgive his suspicion of Harry in “The Chamber of Secrets,” because frankly, in Justin’s position, anyone would be be freaked out. Justin is a bit naive, however, and perhaps too easily manipulated. He was openly an avid admirer of Gilderoy Lockhart, stating in the book that it was thanks to Lockhart’s published works that his mother allowed him to attend Hogwarts. Justin also believed the rumor that Harry was the Heir of Slytherin, even before the snake incident during Dueling Club.
As the years went on, it seems that Justin eventually found his courage and strength. Along with fellow Hufflepuffs Ernie MacMillan, Susan Bones, and Hannah Abbott, Justin joined Dumbledore’s Army in “Harry Potter and the Order of the Phoenix.” Justin also helped defend Harry from Crabbe, Goyle, and Malfoy on the train home at the end of the novel, hurling jinxes at the trio. Justin grew to be a loyal friend, and a good example of an ideal Hufflepuff.
