Terrors in Subnautica II; Humanity Reconstructed(Complete)

Part 1: Rebuilding in Separation

Author's Note: I know the main character is way more developed than the typical reader insert by this point, but for the sake of continuity it will continue as a reader insert. 

"Guys my mother has her camera with her, let's all take a picture together!" Marzia shouts excitedly," I want us to remember this forever!"

The whole group, their families in tow, came together for a memory they'd always hold dear.

                                                                                "We Made It"

Seán ran his fingers over the raised letters of the picture frame they'd hung in the living room. It hung just above the mounted leviathan tooth from their first adventure. He thought back on the day they returned fondly as he recalled everyone reunited with their loved ones. How everyone opted to sleep in the same building for the first week while the doctors briefly looked them over. How their implants showing their stats had been deactivated, save for their base beacon. It was so care free, everyone was so full of life and hope. He missed them.

Looking around the empty apartment Seán couldn't help but wonder how everyone's projects were progressing. The devastation from the war they were gone for was a lot greater than they anticipated; as a result every remaining person has been working to rebuild. Just thinking about the five billion people who died in such a short span of time is dizzying. Considering the violence, stigma, and hatred that's plagued any mutant who have come out since, the population has likely gone down even more.
Those who see humans as slaves don't help either, regardless of only being three percent of mutants.

A month after getting back, the Council of Mutants came to their temporary apartment to ask Y/N if she would be willing to join a new program. The purpose being to both rebuild the world and fight against the darker side of their people. As the remaining Governments came together with the Council, they came to the conclusion she was the perfect candidate. Not only because she is extremely capable, but also because she is for the most part, loved in the eyes of the public. Especially after everything they had lived through having been live streamed, a fact he was still coming to terms with. Not having the heart to hold her back, he told her she should do it.

She's been away for two months now, and sleep has become increasingly elusive as the lonely nights pass by. They've been able to keep in contact, at least; calling one another every other day. Still, sometimes he misses her so much it aches.

Slumping down on the small recliner, he picked up the fabricator from the coffee table. The technology from the event has helped a lot in rebuilding for the non-mutants. A small smile spreads across his face at the thought of all he's been able to help accomplish. It surprises him that all of their channels are still thriving, as they vlog the progress made to recover the cities they live in. Though none of them update nearly as often due to focusing on helping rebuild, it still brings joy to people. Sighing, he groaned at the headache he'd likely caused over forgetting to return the device back to the regulators again. It just felt normal to have one now, he supposed.

*knock knock*

Jolting out of his thoughts, he meandered his way to the door supporting his still healing spine in his hand. A man he didn't recognize was on the other side, though that was more of a norm than it used to be. He opened the door with a tired smile.

The man in front of him was tall, with long curly hair. His clothes we're as dark as the night, his strange gloves covering his forearms clipped into his shirt sleeves. Who is this guy?

"Hey, can I help you?"

"Is Y/N here?"

...

"I'm sorry, who are you?"
