League safe house outside Star City

Night

"You said you've got something?" Oliver asked as he walked back into the room.

"Yeah kid." Slade said.

"Darhk moves his Idol around a lot," Roy began, "but Captain Lance had his tech experts use a lot of satellite imaging. They think he's hauled up at a compound in Sky Woods."

Before Oliver could say anything, Oliver's phone rang. He pulled it out and frowned as he saw blocked ID flash across the screen. Having a feeling he knew who it was, he quickly answered.

"Hello?"

"Now, was that so hard Oliver? Nelson Plaza, three hours. William will be there." Darhk said before hanging up.

"Oliver?" Nyssa asked as Oliver turned around to face them.

"Darhk said he's gonna release William three hours from now at Nelson Plaza." Oliver explained.

"Ollie, it's probably a trap." Thea reasoned and Oliver scoffed.

"Of course it's a trap. Darhk will never give up William now that he knows he can use William to bend me and the League to his will." Oliver said bitterly.

"So what's the plan kid?" Slade inquired.

"One way or another, this ends tonight. Suit up, we're going after Darhk." Oliver ordered.

Star City

Later

"I see nineteen Ghosts." Mari said over the comms as she flew overhead.

"Copy. Speedy, Huntress?" Oliver asked over the comms from where he, Nyssa, and Deathstroke stood.

"We're good." Huntress said from their vantage point.

"Roy?"

"In position."

"Let's do this kid." Deathstroke said and Oliver nodded as he reached back into his quiver.

Oliver notched an arrow, raised it towards the sky, and fired. The arrow neared the roof and then exploded into a flash of light. As the trio walked forward, Ghosts surrounded them. However, Oliver quickly shot out two arrows, killing them instantly as they bodies dropped to the ground.

"You usually don't go for the kill kid." Deathstroke noted as he pulled out his sword.

"I'm not taking prisoners tonight," Oliver said darkly, "Vixen, you're up."

With the cry of an eagle, Vixen flew into the air and crashed down through the roof. She landed on her feet and Darhk whirled around to face her.

"I'm guessing your insurance won't pay for that." Vixen said as Darhk chuckled.

"Cute. Buh-bye," Darhk said before waving his hand and Vixen was thrown on her back, "when you're dead, I'll make sure that totem gets put to better use."

Vixen tapped the totem and was surrounded by a blue leopard cat before it faded.

"Took the words right out of my mouth." Vixen said before she rushed him.

However, instead of going for him, she ducked under his arm and went for the totem behind him on the table. She grabbed it and jumped through the hole she had made in the roof.

"Well…that happened." Darhk said after a moment.

Outside, Oliver fired an arrow, getting one Ghost while Nyssa and Deathstroke whirled around, slashing the other Ghosts. Huntress and Speedy rode up on motorcycles as the last of the Ghosts dropped dead. Oliver turned to them as they got off.

"You two get William, we'll handle Darhk." Oliver said as he gestured to Nyssa and Deathstroke.

At that moment, the front door opened and they all began gasping for breath.

"I'm sorry; I can't hear you over the sound of your throat closing up." Darhk sneered as he walked out.

"We've got the totem," Vixen said as she stood in the woods on the property, standing in front of the totem, which was on top of a boulder, "has it had any effect?"

"Nope." Roy said, taking aim at Darhk.

"Plan B then." Vixen said and Roy nodded mutely as he fired.

The Arrow sailed towards Darhk but, without Darhk moving a muscle, the arrow turned around and went soaring back to Roy. Roy attempted to dodge but growled in pain as he went down, the arrow in his shoulder.

Vixen took a deep breath as the image of a roaring gorilla surrounded her before disappearing. Vixen then picked up the totem before slamming it harshly onto the boulder, spirits of animals surrounding her as she did it repeatedly.

"Please, don't hurt them." William begged as he came out and saw what was happening.

"William." Oliver gasped as he saw his son.

With the roar of a gorilla, Vixen slammed the totem down onto the rock and it shattered.

Suddenly, everyone dropped to the ground. Darhk frantically tried to use his powers to no avail, they were gone. Oliver picked up his sword as he stood up, glaring at Darhk with hate. However, before he could do anything, it was too late. There was a whirling sound and a shuriken suddenly struck Darhk in the neck. Everyone looked on in shock as Darhk's body jolted, falling to the floor with a glassy look in his eyes. Oliver looked up to see someone dressed in black standing off to the side, at the end of the woods. The man stared at him and Oliver got the feeling this man was glaring at him. The man then turned around and disappeared into the woods. Oliver stared after him, considering his next move when he heard the sirens of police cruisers.

"Come on, we need to get out of here!" Oliver barked at the others s they stood up.

They nodded and began to flee. Oliver looked back at William for a moment before he nodded to his son and fled after his team.

League hideout

Later

"William's gonna be fine," Quentin said and Oliver breathed a sigh of relief, all but collapsing into a chair as they stood with the rest of the team in the living area, "but there's a problem."

"What kind of problem Captain?" Helena inquired and Quentin sighed.

"Some of my Detectives questioned William while the docs were checking him out. Darhk didn't take him," Quentin announced to their shock, "it was a guy dressed in black with a hood and mask. Who is he?"

"We don't know." Roy, wincing as Thea bandaged his wounded shoulder.

"But he was working with Darhk, before he killed him. And I think he has an axe to grind with me." Oliver mused.

Argus base

Same time

"Where is my daughter?" Ruve asked as she stood behind the glass cell as Lyla stood on the other side.

"She's been placed in social services. You will never see her again. You spent your life devoted to a madman, now you have the rest of your life to figure out who you are without him." Lyla said as she turned to leave.

"You think it's over, but you're wrong," Ruve sneered as Lyla paused, "someone else is out there, someone who hates Oliver Queen just as much as I do. He will destroy him and everything he cares for."

"Who is he?" Lyla demanded as she turned around and Ruve smirked.

"He calls himself Prometheus."

Starling General Hospital, next day

Morning

Samantha was rushing down the hall, eager to finally see her son again. However, she rounded the corner and froze as she saw Oliver standing in front of William's door.

"Oliver?" Samantha breathed.

"Hello Samantha." Oliver said, lightly tossing her something.

She caught and looked down; stunned to see it was William's Flash action figure.

"H-how did you get this?" Samantha stammered as she looked back up at him.

"The FBI agent who approached you, she's a friend of mine. And she knows, just like I do, that William is my son." Oliver said and Samantha paled.

"How-"

"It doesn't matter," Oliver cut her off, "but we need to prevent something like this from happening again."

"Did you have anything to do with this?" Samantha demanded, assuming the worst and Oliver shook his head.

"Not directly. But what happened to him was my fault and that is something I cannot allow to happen again." Oliver sand and Samantha look angry.

"If you are thinning you are going to take my son from me-"

"I'm not," Oliver quickly assured her as he walked over to her, putting his hands on her shoulders in an attempt to calm her, "but Samantha, because of who I am, I will always have enemies. William is the one thing they can use to exploit me and I cannot allow that again. Take William and leave Central City, don't tell anyone where you are going. Take him somewhere no one will ever find you. This is the one and only thing I will ask you as William's father. Please Samantha."

"Okay." Samantha said softly and Oliver nodded gratefully.

"Thank you." Oliver said as she stepped back.

Samantha walked over to the door and opened it, walking side.

"Mom!" Oliver heard William shout in joy before Samantha closed the door, leaving Oliver staring at it.

"You made the right choice." Mari said as she walked up behind him.

"I know. Doesn't make it any easier." Oliver sighed.

"The best gift you can give William is a normal life." Mari reminded him and Oliver nodded.

"And I can only do that by not being in his life," Oliver said sadly as he turned around to face her, "I couldn't have done this without you. Thank you."

"I'm only a phone call away," Mari said as they shook hands, "take care of yourself Oliver."

Hive Headquarters

Same time

Prometheus stood around the dead bodies of the other leaders of Hive, his sword dripping with their blood. A dark haired woman was behind him, observing the scene calmly.

"You're plan went exactly as planned. Oliver and his team destroyed Damien Darhk's' source of power, allowing you to kill him." She noted.

"Like I told him from the beginning, Oliver Queen is mine." Prometheus declared.

At first, I was gonna have Oliver be the one to kill Darhk, but I think having Oliver kill someone in front of his son is pretty messed up. And this way, it gave Oliver his first glimpse at Prometheus.

In case there is any confusion, telling Darhk about William was basically all part of Prometheus' plan to get Oliver and company to destroy the Idol so Prometheus could kill him. As we know, Prometheus doesn't want anyone else to kill Oliver and Darhk was never gonna stop since Oliver was never gonna comply. This was the only possible outcome of a Darhk/Prometheus partnership.
