Ethan Phillips stated that a scene was shot where Neelix and Kes acknowledge they have broken up, saying, "...we did do a scene where we both acknowledge that we're not a couple anymore. We shot it in the science lab, which was a set we didn't use often. And Kes and I had a closure conversation where we said we want to be friends now ... it was quite a nice tag to the relationship. They never aired it... it was a very good scene. It was easily as six or seven-page scene where we track what happened to us and what we think might have caused the split, but that we want to stay friends."
Preparing for the rescue mission, Neelix visits sickbay and asks for analeptics. Analeptics are restoratives, a.k.a. central nervous system stimulants. The most commonly used analeptic is caffeine.
Neelix's reveal to Tuvok that his knowledge of mag-lev carriages was based on his experience with authentic 1/10-scale models is reminiscent of the scene in The Flight of the Phoenix (1965), where Dorfmann reveals that his airplane construct was based on the design of model airplanes.
Neelix confronts Tuvok over his excessively condescending attitude towards him. From this point onward, Tuvok treats Neelix more tolerably, but never completely loses that air of arrogant superiority.
