The original plan for this chapter was to wrap up the Anakin and Obi-Wan storyline and show that Durge was still alive in two minutes, then roll one minute of credits (which none of the previous chapters had). But when it was decided to include the winner of the Cartoon Network choose a Jedi competition as well as introduce Revenge of the Sith villain General Grievous, the end result ended up being over twice as long.
The Wolfman Jedi, Voolvif Monn was chosen to appear in this episode by way of a competition on cartoon-network.com. He made another appearance in chapter 22, while the characters who lost the competition, Roron Corobb and Foul Moudama got substantial parts in chapters 24 and 25.
