Part 5/8:
With each passing day, John's peculiarities deepen. Instances of John displaying excessive interest in Liberty, including alarming reactions to her bodily fluids, suggest that he harbors a secret much darker than mere interest in environmental problems. Liberty’s suspicions drive her to clandestinely monitor John’s behavior, leading her to discover his bizarre laboratory—where his true nature begins to unravel.
As the story unfolds, Liberty witnesses inexplicable incidents with John that deepen her concern for her mother. The culmination of Liberty’s fears transpires when she discovers that John is not merely a marine biologist, but an alien entity utilizing their family as part of a larger, nefarious experiment aimed at their own survival as a species.
