Lifeless Planet - part 2 - The only one here again...
1While looking for a solution, the Soviet scientists discovered that Aelita, a colonist who had lost both of her children early on in the crisis, had been maintaining a secret garden containing the various plant forms of the planet, among them the now extinct green moss. After observing that Aelita could interact with the plant forms, the desperate scientists experimented on her, injecting her with DNA taken from the plants of the planet. As a result, Aelita transformed into a human-plant hybrid that was able to survive on the planet and influence the growth of its plants. Unfortunately, this was insufficient to prevent the colonists' demise, and all of them were eventually wiped out, leaving Aelita the sole survivor. After discovering this information, the protagonist is led by Aelita to the heart of the planet, where she sacrifices herself to restore the planet's original life forms. This also has the consequence of repairing the previously unstable portals, allowing the protagonist to leave the planet. As the protagonist makes his way to the exit portal, an interview flashback reveals that he had a wife on Earth. One day, she disappeared, later discovered to have fallen off of a cliff and rendered comatose, with a mysterious green moss growing around her toes by the time she was found by the protagonist. Afterward, she was placed under life support, which served as the reason for the protagonist volunteering to participate in the one-way expedition to the planet in the first place: despite knowing that it would take a long time (if at all) for his wife to recover, he was still unwilling to take her off of life support, as he wanted to give her "every chance to live again, even if [he] wasn't there". Reaching the portal, the protagonist returns to Earth, now hundreds of years into the future. Reflecting on his experiences, the protagonist arrives on a cliff (the same one of which his wife fell off) that overlooks a futuristic city.
