D.P.O.

Several crew, including episode director Kim Manners, make a cameo in the form of the yearbook page that Scully flips open.

When Frank Kiveat collapses, the EMT states that his pulse is thready. His partner gets the monitor/defibrillator and the first EMT carries out chest compressions even though Frank is moving spontaneously (i.e. is alive). Then the ECG shows asystole (flat line) before they apply the defibrillator. You cannot use defibrillation on asystole. In addition, Frank appears to be conscious when Darin talks to him and clearly cannot be in full cardiac arrest.

Almost every episode ends with a fade to black and the words "Executive Producer Chris Carter." At the end of this episode, a character is flipping through channels on television, and stops on one showing Carter's credit.
