In the Chamber of Secrets, he was petrified by seeing the Basilisk through Nearly Headless Nick. He along with Mrs. Norris, Colin Creevey, Hermione Granger, and Penelope Clearwater were unpetrified when the Mandrake draft was finished.

In the Video Games
In LEGO Harry Potter: Years 1-4, when Hermione Granger leads you to the potions classroom, he gets added to your party while in the classroom, so you can unlock the Hufflepuff painting on the wall which only corresponds to Hufflepuff students.
- He appears identical to Tom Riddle; both have light skin and Robin hairstyles. The only differences are Justin wears Hufflepuff house colours and he is muggleborn, and Tom wears Slytherin colours and is a half-blood. Justin also appears with a benevolent look, while Tom seems to smirk more.
