Trivia: Tucker's sardonic remark that Ezral create a holographic doctor is an in-joke to The Doctor from Star Trek: Voyager.
Nitpick: The armed holographic crewmen walk through walls to ambush Archer and Reed... but when they disappear, their (presumably real) energy weapons drop to the ground. Since the weapons are real, the holograms could not have brought them through the walls (unless the holograms for the guns were not turned off when the crew holograms were).
Trip: What if she gets sick, will you create a holographic doctor...? That's crazy!

The plot of this episode is similar to the Star Trek: Deep Space Nine season two episode "Shadowplay", in which Rene Auberjonois (Odo) and Terry Farrell (Dax) played the roles the Enterprise crew play in this episode. Rene immediately saw the similarities of the two and pointed it out to Scott Bakula (Captain Archer).
