Page "The Voyage Home (The Outer Limits)" Paragraph 7

The alien creature explains that the death of his crewmates was unavoidable — and an unintended cost of his lifecycle, but that particular phase has passed.

A further serious failure occurs on the ship, and only Ed can fix it.

The alien pleads with Ed to help him, and explains that it can bring many benefits to Earth — cure for cancers and environmental technologies.

Still skeptical but hoping there may be a way out, Ed works with the creature to fix the problem.
