As he travels between worlds, Oliver relieves his life. He wakes up on a bed in a cheap apartment, and the Monitor warns him not to interfere. The Monitor explains that he redirected Oliver after he intervened to save Laurel on Earth-2. The alien says that a world being wiped from existence is a herald of what is to come, and informs Oliver that everyone there is no more. The Monitor says that Diggle and Dinah are nearby, and if Oliver fails then all Earths will be destroyed. Oliver insists that he wouldn't let Dinah die again, and the Monitor says that Oliver must obey his orders to save the Multiverse.
Oliver wonders where they are, and the Monitor explains that they're on Earth-1. He tells Oliver to bring Dr. Robert Wong to him and refuses to explain why.

The two men take out the gangers, and down the hallway the Earth-2 Dinah uses her sonic scream on another ganger.
The trio go outside and Oliver realizes that they're in Hong Kong. Oliver explains that Earth-2 is gone, but Laurel asks for the breach device so she can go back to Earth-2 and look for survivors. The device is broken, and Oliver says that they have to focus on the mission. Laurel doesn't care about anything except saving the survivors on her Earth, and Oliver tells her that there's no Earth left to save. She points out that the people who died were just copies of the people Oliver loved, but they're real people to her. Once Laurel walks off, Oliver tells Diggle that she's processing her grief and they figure they have to get going on their mission.

Zoe says that she knows where JJ will go to sell the valuables, and Mia, Connor, and Zoe head there while William works on the flash storage.
Oliver and Diggle go to an ARGUS safehouse, and when Diggle says that "Harbinger" gives her regards, the owner lets them into a secret room. Inside, Diggle says that it's all hands on deck and explains that the machine is hooked up to ARGUS' Intranet. Oliver admits that he ignored the orders of a cosmic being and watched a world disappeared, and suggests they not make the mistake again. Diggle tells Oliver that he shouldn't have blamed himself.

More Deathstrokes come in with Zoe, and JJ figures that there's a better way to resolve things but he has business to attend. He suggests that he and Connor have a friendly chat, and Connor agrees despite Mia's objections.
Oliver thinks about his past with Felicity, and Tatsu tells him that her contact in the police was afraid when she mentioned Wong. Diggle and Oliver have discovered that Wong was working on a top secret project for the Chinese government, and the secret police put him in protective custody. They have him at a safe house and are going to move him that night, and the trio head there.

Tatsu and Diggle are monitoring him from the safehouse, and Arrow starts the upload. Staring at the file, Tatsu realizes that Wong is recreating the Alpha/Omega virus. In the lab, Oliver realizes that Wong has already succeeded.
When Oliver returns to the safehouse, the trio figure the Triad don't have the virus yet. He reveals a canister of the virus and figures that he'll use it as bait to draw China out. Tatsu says that her husband did the same thing, but Oliver notes that Maseo planned to give the virus to China and he isn't. The others don't have a better idea, and Diggle goes to make arrangements.
At the ARGUS safehouse, Lyla tells Laurel that she knows what it's like to lose people. She admits that she doesn’t know what it feels like to know a universe, and Laurel says that all of the people she knew are dead and don't deserve to be gone. Lyla tells her that she's trying to be better, and Laurel wonders if she's where she's supposed to be. Her new teammate says that when she was in Afghanistan, none of her squad members made it back. Lyle used to lie in bed wondering why she didn't die with them, and says that she knows something about survivor's guilt. Laurel asks if it gets any better, and Lyla says that it doesn't and all they can do is move forward by not giving up and doing the right thing. Lyla tells Laurel that they honor the dead by fighting for the living, and Earth-1 needs Laurel as well.
Oliver promises Tatsu that he's not going to let China get the virus. Tatsu reminds him that he failed nine years ago and her son died, and Oliver's guilt over the failure stole his humanity. She wonders if the Monitor will use the virus for something worse than the Triad, and Oliver says that he doesn't have a choice. Tatsu points out that the Monitor doesn't care who gets hurts, and Oliver figures that if he's wrong then everything he's sacrificed is for nothing. Oliver insists that he needs his family to live, which means he needs the plan to work. He figures that there is no other choice, and Tatsu says that there's always a choice.
Connor and JJ sit down for a drink, and JJ says that Connor has a place with the Deathstrokes. Connor talks about how JJ got him out of a gang in high school, and JJ notes that Diggle blamed him.

JJ insists he's not that kid, and Connor tells him that he knows who he is and it's not too late.
