Rick, Morty, and Summer follow a distress beacon onto a ship being absorbed by a hive mind that turns out to be Unity, Rick's ex, who now controls an entire planet. Rick and Unity immediately resume their relationship at civilizational scale while Summer attempts to liberate the population, triggering an instant race war over nipple morphology. Back on Earth, Jerry and Beth discover an alien chained in Rick's secret lab; the alien breaks free, delivers a formal indictment of their marriage, and leaves. Unity eventually evacuates the planet and ends things with Rick via a goodbye letter distributed through every body simultaneously. Rick returns home, concedes to Beth without argument, retreats to the garage, and narrowly survives a suicide attempt.
The episode establishes Rick's emotional life as something real and damaging rather than absent. Unity's farewell letter names exactly what Rick does to the people around him, and his response — no deflection, no performance, just a quiet attempt at self-destruction — reframes his usual behavior as coping rather than character. The B-plot earns its place: Blim Blam's exit speech lands harder because it comes from someone with no reason to care, and it lands on the marriage rather than on Rick.
