Vorik's interest in Torres is hinted at in Alter Ego (1997), where he reserved a table for just the two of them during a luau in the Holodeck.
According to Vorik, there are seventy-three male crew members aboard Voyager. Since ten crew members have perished since Janeway gave the crew complement at 152 in The 37's (1995), that would mean there are 69 female crew members aboard, for a total of 142.
Tuvok's right elbow is revealed to be an artificial replacement, a result of an injury during a combat simulation.
This is the second of two episodes in which Harry Kim does not appear, the first being Fair Trade (1997).
