Rocky awakens aboard the Hail Mary suffering from complete amnesia, sharing this confusion with human crewmate Grayson. Their initial interactions focus on basic survival and establishing communication through universal concepts like mathematics and music. Slowly, fragments of his past return as they work together to repair the ship and understand their surroundings. These recovered memories reveal he is an engineer from a distant world sent to solve an existential crisis facing Earth.

As they identify astrophage as the killer threatening humanity, Rocky remembers his specific mission parameters involving biological cures. The critical turning point occurs when they realize the return trip requires more energy than available reserves can provide. With no other options remaining, Rocky accepts that his life force must fuel the drive to ensure the cure reaches Earth in time. This final act of memory and purpose solidifies his commitment to saving a species he never intended to meet, transforming him from an unknown stranger into a legendary hero.
