In "Harry Gets Nosey", Harry learns he is allergic to cats.
Harry is played by Matthew A. Wilson. Like Bianca, Harry's last name is the same as his actor's. However, unlike other Cyberchase For Real protagonists, his first name is different. This may have been to avoid confusion with Matt, a main character in the animated segment.
