### Season 2

Erik waits impatiently, wanting to know how Jana is and asks for a sign to know she is okay. He is met with a door, which he goes into, but is led out of the Artifact. Seth Gage introduces himself and says that the Department of Homeland Security sent him, but Erik does not care. Seth tells him that he cannot help him and wants to talk to Harper, but Seth tells him that they have no idea where Harper is and tells him they should talk.

On Earth, Erik tells Seth that he feels like a cat outside the Artifact and says that he is afraid of the bigger picture - what he would have to give up for food and a warm lap and questions whether or not communicating with the Achaia was the right thing, which Seth confirms. The Artifact opens and Erik walks inside.

Erik goes to the Artifact and tells them that he knows he has asked them for a lot, but says that the task is easy to them, However, the Artifact remains closed until Seth approaches it and the door opens for him. Erik tries to stop him, but Seth does not listen and goes inside.

Erik is handed a cup of coffee by a woman, who talks about her deceased wife and also wonders if the Achaia had found a way to cheat death. The door to the Artifact opens and Seth walks out. Erik tells them that Harper had killed many people when she had the implant on her head and Seth reveals he had accepted the object on his brain. Erik wonders how he could let that happen when his wife was sacrificing her life for the planet. Seth tells him that that would be Niko's legacy, which alters Erik, but he is taken away. After that encounter, Erik looks at the card that the anti-Achaia group had given him.

Erik makes it to the anti-Achaia group and tells them that Seth had a "spider" on his head. He tells the leader to remove her mask, which she does. He tells her that he is there to see Harper Glass since she could talk the Achaia into bringing Niko back.

Erik and the woman walk into a room where he sees that they were analyzing an Achaian implant in real-time; however, they never said that it was Harper's. Erik says that Harper and Seth were the only people with an implant. She tells him that Harper had killed some of her people, which means that she had killed Harper by ripping the implant out of her head. Erik complains that her wife would die now, but she offers to help if they receive the data dump, but Erik leaves.

Erik tells Singh that he needs to get to Cas even if it is for a couple of minutes. However, Singh is approached by a soldier who tells her that she needs to leave the site since she no longer had security clearance. Erik complains to Mackenzie telling her that Singh had been taken, which he is told is due to leaks. She tells him that Seth was worried about the leaks, but Erik asks how Seth is relevant if he had an implant in his head, but the woman says that they want to communicate with the Achaia effectively. Seth approaches Erik and asks them if they are ready to receive the crew of the Salvare.

Erik visits Seth's office and sits down. Seth asks him why he had given his bio-ID to their enemies, but he does not know how that happened. When asked who it was, he tells him that a group of self-styled resistance fighters tried to recruit him, but he told him that he was not interested. Seth asks how he could meet with them, but Erik says that he does not have their address. Seth says that when he took over the Achaian portfolio, he put a tracker on Erik and all USIC staff and the two go for a drive.

USIC visits and shoots the self-styled resistance fighters, killing all of them. The leader calls Seth a traitor and yells at him for having an implant. However, Seth says that he is happy with his implant and does not want them to disrupt an Achaian-Human alliance. He asks her for Harper Glass, but she tells him that she would never confess. He grabs her head and starts drilling into her eyes in order to receive information. When Erik tries to stop it a soldier's eyes glow white and he is stopped. Seth then grabs Erik's head and smiles, saying that Erik had told the truth and asks him to be careful with his bio-readings and advises him to stay friendly.

Mackenzie tells Erik that Niko had been a competent commander, but Seth says that was until they encountered a magnetar. They mention that Javier was left dead after an unnecessary medical procedure. Seth and Mackenzie know that the crew of the Salvare was being dishonest, so Erik recognizes that they wanted to use his wife's memory to manipulate them, which he refuses to do. Seth tells him that he gets it, but they are using him since they want to know what happened around the magnetar. Seth tells him that he could get that information by other means but does not want to resort to that.

Seth approaches Zayn, which makes hir ask what ze is doing there. He tells hir that he can read people and could tell that ze was lying. Ze says that ze would like to be with hir mother since she was sick, but Seth tells her that her mother only has a day or two at the most. Seth tells her that the Achaia could save hir mother's life if ze confessed.

Cas gets a knock at her door; Erik says that he hopes he is not being followed and asks her what information she was withholding, but she says that she had not revealed anything to him. Erik asks her to remember what she had told him, but she says that she does not remember. Erik asks if she remembers anything about the magnetar and she thinks it is weird that she does not remember. Erik tells her that Seth had probably wiped her memory

William tries to contact Erik, who does not pick up. He tries Cas, but is blocked and is hurt by Seth, who ordered for him to be moved to the particle accelerator. Seth tells him that he needs information, since he is part Achaia, just like William. He reminds him what high-density neutrinos do to Achaians and knows that he was trying to turn it into a weapon.

Seth tells William that he knows how to make him talk, so he shows him his "mother," Ursula Monroe.

Seth is in pain from his implant, asking it to stop. He tells Ursula and William that they knew where Niko and Richard were, saying that it was a planet orbiting a star called Citalá. He also says that she would be replacing him if he could not extract William's data. Ursula asks for more time, but William says that he can decrypt the data in exchange for a deal. He asks if his coding could be passed to an implant that could be put in Erik's head. Seth says that the implant needs to be accepted in order for it to last longer, which disgusts Ursula, so she wants to leave. Seth tells her to shut up, and tells William that he could bring Erik to him.

William reaches Erik and Cas, telling them that Ursula had located the data, but is brought back. Cas grabs an axe and both of them head towards Seth. Both of them fight USIC security, though Cas does a better job of it, so Erik is dragged away.

Erik is taken to Seth, saying that he is disappointed at Ursula for working for him. Ursula tells Seth that it was not necessary to force William, but Seth does not listen to her and tells William that he could proceed. He tells Erik that Niko is alive and safe, but what they needed in order to bring her home was for him to accept an implant, becoming William in the process. Erik reminds William that Niko trusted him and Seth says that he would call Jana, asking her how she would feel becoming an orphan, so Erik accepts.

Seth shoots a guard, telling Ursula that she needed to press delete on the data William was decrypting. The guard's implant comes out and heads towards Erik. Seth tells William to jump in before he changed his mind. However, William refuses until Niko and Richard were safe.

Seth goes to the Artifact, meeting Richard and Niko. She tells him that she is ready to negotiate and he introduces himself, saying that he had taken an implant after she turned it down and was the Achaia's spokesman. He tells her that he could open the door to Earth and does so. Richard asks if they could walk through.

William calls Cas, telling her that Seth had opened the bridge to Earth. She jumps down from the ceiling and is told by William to distract Seth in order to have him weak and occupied. Ursula tells William that she wants to help, and offers to protect his code. William goes inside the implant as Cas punches Seth repeatedly, which makes him bleed.

Seth notices he was betrayed by William and starts choking him. Niko tells him to let William go. William tells Seth that when Iara encountered the Achaia, they strangled her, but she was not ready. However, he says that he is ready and knocks him to the floor. He tells Niko and Richard to run, but the former asks if he can get back, which he says he would try. Niko and Richard run towards Earth and make it back, which makes them happy.

William tells Seth that he was not a robot, and he was not a human, so he could hurt him. Seth leaves the Artifact and stops one of Cas's punches, choking her. Ursula tries getting William back out from the Artifact, while Seth approaches the implant that was going to be Erik's. William appears and says that perhaps he was too fast for him. Cas approaches Seth from behind and chokes him, but he says that even if they killed him, the Achaia would be there since they were pissed.

Cas drags Seth away while Erik understands how neutrinos worked on the Achaia with William. William says that they need more neutrinos, but whenever he did it, the magnetic confinement was overheated. Erik asks if they could back off on the accelerator beam, directed equal power into the cooling systems and then toggled between the two. Ursula, William, and Erik give the theory a go.

Niko, Richard, Bernie, Zayn, and Dillon are all in shock as they see that the Salvare had been blown up by the Achaia. Everybody is happy that the neutrino bomb had worked, and Niko asks if it could work again, but William says that they do not have enough time. Mackenzie asks what they could do now, and Cas says that there was only one way to find out, which would be using Seth.

Mackenzie and Niko interview Seth, saying that relations between humanity and the Achaia were in a bad spot. Nothing had warranted an attack on the Salvare, but he asks how they could defend themselves from a species that had saved her daughter's life. Niko tells him that wherever the Achaia went, death had followed, but Seth says that it is the other way around and says that their weapon was just a mosquito bite, telling them that the Achaia would be forced to respond unless they met their demands, which were new ones.

Seth says that the Achaia's demand was to allow numerous Artifacts to land on Earth, and also to accept all of their gifts. This was advanced tech to help humans achieve their potential, but they also wanted the Salvare destroyed. He tells them that they have 24 hours to decide, and they ask what would happen if they refused. Seth tried to answer, but his head started hurting, and suddenly exploded.
