Scheduled to premiere on USA Network on May 19, 2004 after ABC canceled the show, but USA Network canceled yet again, so the US-premiere of this episode was on digital cable channel 'Sleuth' on October 10, 2006, but worldwide premiere was apparently on French channel TF1 on December 4, 2004.
Based upon the inconsistent appearances of Roselyn Sanchez (shows #2, 6, and 9) in season 2, this was likely the true series finale. She was introduced as joining the RHD in #2 Coyote (2003), and it's implausible she would only appear in a piecemeal fashion once joining the unit.
