 The episode shared themes with previous episodes from the first season such as "Ice" and "Darkness Falls", which both featured the agents finding new lifeforms in remote locations.James Wong was somewhat negative concerning the episode's similarities to "Ice", saying, "If the show starts to cannibalize itself, there's going to be trouble".Gordon stated, however, "I know there are some similarities with 'Ice', but I think once you get beyond the similarities of a group of people in a confined space going up against a creature, there are enough differences to separate the two".
