In the TV series, Duncan and Isadora are portrayed by Dylan Kingwell and Avi Lake, respectively. The TV series portrays a romantic relationship between Duncan and Violet that is not seen in the books, as Lemony Snicket did not reveal that Duncan has a crush on her, but was originally depicted there with Quigley. It was also suspected that Isadora had a crush on Klaus. Much like the novel, they escape with Hector in the hot-air balloon. They briefly appear in "The End", where Lemony postulates that they successfully reunited with Quigley.
