Continuity mistake: As the men are lined up, Klink starts to grill Hogan. Klink has his pistol aimed directly at Hogan, then it's at a 35 degree angle toward and close to Hogan's face. A moment later it's about two feet away from his face.
Continuity mistake: In this episode, the picture next to the light switch wire is a group seated around a table. In "The Defector" (S5:Ep10) the picture was of Hitler making a speech, and the microphone he's speaking into hides the Heroes' bug.
Continuity mistake: Toward the end of the episode, Hogan turns Shultz around, grabs one of the grenades Shultz is carrying, and hands it off. The one grabbed was closest to Shultz's left side. A few moments later, Shultz turns his back briefly to the camera; there is now a space between the grenades, as if Hogan grabbed the middle one.
