An unidentified flying object contacts Jimmy directly, instructing him to go to a beach. There, he meets Remi, who becomes his love interest, and her younger brother Chobi. The UFO then teleports all three against their will. This entity communicates that humanity has lost its capacity for empathy through environmental destruction and intends to teach them a lesson by exposing them directly to prehistoric events.

Displaced into the Cretaceous period and later the Ice Age, Jimmy remains largely passive and reactive. He rarely displays emotional responses or makes proactive decisions, even when witnessing traumatic events like dinosaur predation, volcanic eruptions, and mass extinctions. His expressions are consistently blank, showing negligible character development or altered perspective. His interactions mainly involve observing Remi and Chobi, forming no significant relationships with others, including the orphaned Triceratops Zhu, who bonds solely with Chobi.

The UFO eventually returns the group to their original time after showcasing humanity's historical violence toward nature and each other. Jimmy receives no explicit resolution regarding his personal struggles, relationships, or environmental concerns. His background, actions, and psychological state remain unchanged throughout the documented narrative.
