episode script on a Sunday afternoon before the episode was to be released on Friday. Scripts were written with minimal planning as the storyline grew beyond the 6 to 8 episodes originally expected. Church's death, as well as the revelation of Tex as a female character, both of which drove most of the season 1 plot, were conceived shortly before their respective episodes began production. In January 2005, Burnie Burns and Kathleen Zuelch were interviewed in an episode of The Screen Savers on G4.

The second issue involved the pacing of events leading up to those planned for the special 50th episode. The events initially envisioned for the episode were then deemed too many for a single
