 The episode's premise became a recurring theme in the series, with episodes such as "Darkness Falls" and "Firewalker" repeating the combination of remote locations and unknown lifeforms. A similar plot was featured in "The Enemy", a 1995 episode of Morgan and his writing partner James Wong's series Space: Above and Beyond, and according to UGO Networks the Fringe episode "What Lies Below" has "basically" the same plot as "Ice". The episode introduced invertebrate parasites as antagonists in the series; this plot device would recur in "Firewalker", "The Host", "F. Emasculata" and "Roadrunners".
