Part 7/9:

When the silence of space is finally broken by a distress call from a neighboring ship, the Berkshire, LEL is filled with equal parts dread and relief. The rescue team instructs him to jettison the remaining dome but warns against detonation due to the risks involved. In his heart, the realization dawns—without sunlight, the dome's life-supporting environment has become a suffocating trap for the plants.

Taking decisive action, LEL activates artificial light systems within the dome, desperately trying to revitalize the destitute greenery. In a bittersweet moment of sacrifice and foresight, he jettisons the last dome, sending it drifting away, entrusting Dewey with the last vestiges of Earth’s forest.
