Nadia leads Shiki's group to a volcanic cave containing a beacon to Mother left over from the temple's stolen treasure. With the crew unable to cross, Witch enlists the help of Laguna, who has been hiding on Blue Garden since Drakken's defeat. Meanwhile, Nadia talks about her human mechanic and lover, Andrew, who left 200 years earlier to recover the treasure, the theft of which has deactivated Red Cave's other robots and flooded the planet, leaving Nadia sustained by an energy cable. Rebecca realizes the corpse outside is Andrew's, but withholds the truth to spare Nadia's feelings, as Nadia believes humans are as long-lived long as androids. Witch and Laguna's powers allow Shiki to safely to obtain the beacon, revealed to be a trace of Mother's Ether from a Relic, one of several artifacts imbued with her energy. Before the crew leaves in search of more Relics, Witch informs Nadia of Andrew's death by an asteroid collision that trapped his ship in orbit during his return with the Relic. Nadia severs her cable in her grief, but regains her will to live when the Relic's power saves her, revives the other robots, and restores the planet to its original state.
