The narrative follows two brothers, and Fletcher , living on a frozen, colonized planet. In a society where almost everyone is "modded" with genetic enhancements for superhuman strength and speed, Sedgewick remains "unmodded," leaving him an outsider in his own community.

By focusing on an "unmodded" protagonist, the episode touches on themes of natural versus artificial capability and the social isolation that comes from being "ordinary" in an extraordinary world.

Critics and viewers often rank "Ice" as a standout of the second volume due to its and world-building. While some noted that the short duration limits the depth of its supporting characters, the spectacle of the Frost Whales remains one of the most iconic images of the season.
