The scientists return, the explorers are rescued unharmed, and a giant effort is begun to restore the ancient world's biosphere. The travelers stir and resume their debate, and Planet and Sky are reborn to live again and revel in the wonders that are re-created through the efforts of the scientists.

Planet is plunged into a deep sadness and feels guilty for not being strong enough to hold on to Sky. He projects his awareness to various parts of his world and discovers a lifeform that has some miraculous properties.

Sky has terrible news for Planet. She is floating free of his gravity and their time together has come to an end. She expresses a range of emotions, from sadness and grief, through fierce resistance, and finally acceptance.

The three travelers debate the significance of a changing pattern in the climate towards colder weather. The first is optimistic, but the second insistent they are now threatened, and the third retains its usual contentment.

Planet sings a song expounding upon all the ways he loves his dear companion, the ever-present Sky. She intrudes upon his song briefly to air her concern for their distant future.

Planet and Sky are young and full of energy. Beneath the surface tectonic plates are colliding, creating earthquakes and volcanoes. Above, amidst Sky's powerful storms, meteors and comets are bombarding the surface. One of these arrivals contains the seeds of life.

A rescue party attempts to find the missing explorers and instead finds themselves transformed into primitive beings traveling through deep space en route to an uncertain future.

A woman and a man are reborn as Planet and Sky. Planet thinks he is alone and perfect. Sky informs him of her presence and convinces him of the value of their union as a single world.
