What Could Have Been: An article in Television Chronicles stated that Hanna-Barbera had planned at least 39 episodes for the '80s run of Jonny Quest. The dismal ratings and negative reaction played a part in the series' cancellation after episode 13.
Jessie Bradshaw was originally conceived as a character that would appear in a few episodes of the '80s series as a female counterpart to Jonny. When it came down to the actual episodes that were finished, she only appeared in "Deadly Junket". The misconception that she was a regular new addition comes from the writer stating his original plan, as well as fans confusing her with the later Jessie Bannon incarnation.
