Two thugs were harassing a man and a woman in the street as Daredevil descended from above, beating up the thugs. One of the thugs ran away in fear as Daredevil beat up the other one, lying on the ground until his face was bloodied and bruised as Matt panted out in exhaustion, letting out his frustration and anger as the thug was knocked out.

City Hall

"Oliver, do you know where Mr. Murdock is?" Moira asked as she went out with Oliver and Sara, while on her wheelchair, alongside with Roy and Thea, who was holding Lian.

"He said he needed some time alone to think, it's been… quite a lot." Oliver said before they heard sound of clapping. The five of them turned around in alarm as Darhk appeared, smiling smugly, while clapping hands.

"Sorry for the intrusion. Good to see you're well, Miss Queen, for what it's worth." Darhk said as he looked at Moira on wheelchair as they all glared.

Snarling, Oliver attempted to lunge at Darhk but Darhk raised his hands and Oliver was restrained by Darhk's magic.

"What do you want?" Moira demanded.

"I tried to bring you into the fold, I kidnapped your dearest ones but none of that took." Darhk said.

"You have no idea who are you messing with." Oliver warned.

"Perhaps but as they say, or at least should, the fourth time's the charm." Darhk said as Oliver's phone buzzed and he pulled it out to see a video of William and he and Sara paled. "William thinks I'm friends with his mother. Funny." He turned around to enter a limo. "You're gonna hold a press conference and step down as the mayor at 6 o'clock, Friday, Miss Queen. Oh, that's 6 P.M. by the way, I'll be at home watching you from my brand new television."

Darhk entered his limo as Oliver, Sara, Roy, Thea and Moira shot him death glares.

Later, the Lair

"Wow." Klein said as soon as Oliver filled him in, amazed. "How did Darhk even find out about your kid?"

"He was able to figure out who I was, he's resourceful and smart." Oliver said. "Klein…"

"Call S.T.A.R. Labs, got it." Klein nodded. "I'll see if I can get Mr. Murdock back too."

City Hall

"I came as soon as I heard." Matt said as he was adjusting his tie, as Oliver was entering the conference room, where was Samantha.

"Have you heard from William? Do you know where he is?" Samantha implored.

"I'm doing everything I can." Oliver assured her.

"I knew it." Samantha hissed. "I knew the second he was gone, I realized that you had to have some sort of involvement in this. What was I thinking, letting you get into his life? Two months later and he's missing."

"Samantha, I need you to tell me exactly what happened." Oliver said calmly.

"No, Oliver, you need to tell me what the hell is going on and you need to get my son back, right now!" Samantha exploded.

"I'm trying but you need to tell me what happened, please."

Samantha passed by Oliver, despair all over her. "I went upstairs to get William for dinner and he was gone. Gone. No note, no signs of struggle, just vanished. I called the CCPD and they've been looking everywhere but it's already been 48 hours and still nothing, then a crime scene technician pulled me aside and told me that I needed to talk to you about this."

"Barry Allen?" Oliver realized.

"Yes. That's the one. Oliver, you promised." Samantha cried out. "You promised me that you would tell about my son only to—"

"He's a friend, a mutual friend of ours is the one I had do the DNA test." Oliver explained. "But right now that doesn't matter, what matters that I'm gonna do everything and I mean 'absolutely everything' in my power to help get him back."

"What can you do, Oliver?! What can you do that the entire police force hasn't been able to do?!" Samantha demanded.

"Samantha. I'm the Green Arrow." Oliver said as Samantha stared at him in shock and disbelief.

The Lair

"This doesn't make any sense." Samantha muttered, still in shock.

"Like I said, I'm not the person that I used to be." Oliver assured her before introducing her to the team. "Samantha, these are my friends and you probably remember…"

"Sara Lance." Samantha whispered.

"I promise you, we're gonna find William." Sara assured her, holding Samantha by her shoulders, accompanying her away.

"Does the CCPD have anything?" Oliver asked, once they were gone.

"Uh-uh. Mr. Allen said that they found nothing." Klein shook his head. "Do we have any other leads?"

"Finding William isn't the problem, beating Damien Darhk is. Every time we've faced him, we've been beaten thoroughly." Diggle pointed out.

"Because we're fighting against magic." Colleen pointed out. "Look, from what you guys told me about how this fight with Darhk's been going, I think we need to try a different strategy."

"What about Constantine?" Diggle suggested.

"He's in Hell." Oliver said.

"And I'm guessing literally in Hell." Matt said and Oliver nodded.

"Oh." Colleen muttered. While she had seen her share of strange, supernatural of this kind was something different to swallow.

"But I might know someone else." Oliver said.

Detroit

Vixen took down some gangsters with her magical totem before one thug tried to sneak on her with his gun, only to be shot in his arm by the Green Arrow before she knocked him out.

"I had that under control." Vixen whirled on him.

"I know." Green Arrow nodded.

"What? Not enough in Star City to keep you busy?" Vixen asked sarcastically.

"I need your help."

Later, the Lair

"I have got to get me one of these." Mari quipped as Oliver accompanied her into the lair.

"Hey, Mari." Sara smiled.

"Sara." Mari hugged her tightly as both women laughed.

"Mari, this is Cameron Klein and Colleen Wing and John Diggle." Oliver said as Mari shook her hand with them. "And this is Samantha. William's mother."

"She's a friend. A hero in Detroit they call 'Vixen'." Sara explained.

"Mari and I had an… animated encounter last year and we've stayed in touch ever since." Oliver explained.

"How are you gonna help me find my son?" Samantha asked.

"With magic." Mari explained.

"Magic." Samantha repeated, as if she thought Mari was joking as she was getting angry.

"Yeah." Mari sighed, not blaming Samantha. "It's a long story but a short version is that this totem…" She showed her necklace. "Gives me the ability to channel the Ashe of any animal. Do you have anything of William's with you?"

Samantha showed them a Flash action figure as Mari sniffed it before shooting a glare to Oliver. "Don't you dare tell Barry about this." She smelled the action figure before turning to the team.

"He's still in the city, I think I can find him."

Star City

The Green Arrow and Daredevil zip-lined down to the balcony, swiftly taking down the Ghosts as Spartan provided cover fire while the Canary, Colleen and Spartan were inside fighting and the Green Arrow and Daredevil jumped through the window into Darhk's apartment as he smiled.

"You never learn, do you?" Darhk taunted.

"Where's the boy?!" Green Arrow asked.

"He's fine. I had him moved about two minutes before you and your posse disturbed my evening in. You know, you might wanna learn to be a little more discreet. Have you considered black instead of green?" Darhk taunted.

Oliver took a step forward, glaring. "Tell me where you've taken him…"

"Or what? You'll fight an arrow at me?" Darhk mocked. "I think I've seen this movie before. I win, you lose, rinse, repeat."

"This time it's different." Green Arrow said before Vixen jumped in with a roar of gazelle, lunging at Darhk.

"Where's the boy?!" Mari snarled.

"You have some very interesting friends." Darhk laughed before restraining Vixen, Daredevil and Green Arrow telekinetically. Then he noticed the necklace the former wore. "My, my, I haven't seen that in dog's age. M'Changa province, am I right?"

Darhk tossed her aside and restrained her again but her magical totem didn't make it easy to him. Vixen tapped her necklace, summoning the Ashe of gorilla. Darhk threw Vixen across the room as she attempted to attack him but in the process he freed Green Arrow and Daredevil.

Oliver whacked Darhk in the face with his bow and Darhk dodged as Matt attacked with his billy clubs. Darhk kicked Oliver as he fell over a table and threw him and Matt out through the window before Mari grabbed them both.

"I got you!" Mari cried out as she pulled them back in, while Colleen and the Canary entered.

"Where's Darhk?" Colleen demanded.

"I can't track him." Mari said.

"Darhk's protected by magic." Oliver explained.

"No, not just Darhk." Vixen shook her head. "I lost William."

Oliver sighed, frustrated and desperate.

Later, the Lair

"Where's William? What happened?" Samantha asked.

"A little setback but we'll find him." Sara held Samantha by her shoulders.

"Setback? What do you mean?" Samantha scowled.

Klein tossed Oliver his ringing cellphone. "Blocked ID."

Oliver picked it up. "Hello?"

"You really don't know when to quit, do you? Bursting into my place, completely unannounced. Very rude." Darhk said.

"I want to talk to my son, Darhk, I want to know that he's safe." Oliver demanded.

"Well, this must be the first time your son's been kidnapped because clearly you don't understand how these things work; I make the demands." Darhk threatened.

"I want to know that my son is safe!" Oliver snapped.

"Your mother steps down as the mayor and you are both going to completely endorse Ruve Adams, save us all the trouble of those pesky write-in ballets." Darhk ordered.

Oliver hung up. "He's moved up the timetable."

Mari approached him while Quentin just entered.

"I'm so sorry, I know you brought us here to fight magic with magic but…"

"Mari, this isn't not on you." Oliver assured her. "There is still so much, that we don't know about Darhk's power. We don't even know what the source of it is."

An idea then suddenly hit Mari.

"Wait. I get my magic from this necklace." Mari realized as she held her totem. "Without it, I'm just some wannabe fashion designer who lives at home with her foster dad. Up to now, almost everyone I've gone up against with mystical powers has had some sort of totem like mine. What if Darhk has an object that helps him with his magic?"

"I think he does." Quentin agreed as he entered. "I walked in on him once or twice in front of this cabinet thing and inside was some kind of idol."

"Can you draw it for me?" Mari asked.

"Yeah, I give it a whirl." Quentin nodded as he followed Mari.

"Oliver, what if this little art project doesn't yield any results?" Diggle inquired.

"It will." Oliver said.

"We don't have time to find out, Oliver." Matt protested.

"Mari and Captain Lance are working on a way to eventually stop Darhk. Right now, I have to save William." Oliver said.

"Oliver, you can't trust him. We've already given into his terms before and he crossed us. There's no guarantee he'll give your son back, if your mother steps down." Matt argued.

Oliver considered before remembering what happened with Fyers, Slade and Isabel Rochev.

"It's Khushu idol; very rare and very powerful but it needs constant connection to the Earth's ley lines." Mari showed them a map with lines all over it.

"What?" Diggle asked.

"Think of Wi-Fi as magic and the idol as a connection…" Mari explained. "And if Professor Macalaster's theory is correct and this map is accurate…"

"…then Darhk must be in one of these ley lines in order to get the strongest signal." Diggle realized.

"If we cross-reference the lines with all the places where we've faced Darhk, we'll find him." Klein nodded as he went to the computer.

"Oliver, why didn't you listen to this man's demands?" Samantha demanded.

"Last time I tried that, was when he kidnapped Laurel, Tommy, Quentin and Foggy. And he backed out on his word and tried to kill them. I can't take that chance, Samantha." Oliver said and Samantha nodded, still angry but more understanding as she calmed down.

"There's no guarantee with him." Sara added. "We can't trust that he'll uphold his word."

"But we have a chance now to take his magic out of the equation for good." Colleen pointed out. "No magic for Darhk means…"

"…game over." Matt finished.

"Samantha…" Oliver turned to her. "He's your son. It's your call."

"He's your son too, Oliver." Samantha approached him "Get him back and take this son of a bitch Darhk out."

Later

"I count seventeen Ghosts." Vixen said as she flew over the compound.

"Copy that." Green Arrow said.

Green Arrow fired a flashbang arrow into the sky as the guards burst out and the Green Arrow took them down before Vixen landed down with a shriek of an eagle.

"Guessing your insurance won't pay for that." Vixen quipped.

"Cute. Bye-bye." Darhk knocked her on the floor with a swing of his hand. "When you're dead, I'll make sure that totem gets to good use."

Vixen was covered by a shade of blue lion as it faded while roaring. "Took the words right of my mouth."

Vixen snatched the totem and jumped through the hole in the roof.

"Well, that happened." Darhk quipped, stunned.

Vixen approached Spartan with the totem. In the meantime, Darhk left the house as he restrained the rest of the vigilantes telekinetically.

"I'm sorry, I can't hear you with your throats closing up like that!"

"We have the totem, has it had any effect?" Vixen asked.

"No. You need to hurry. They're in trouble." Klein said.

"Go for plan B." Spartan said as Vixen grabbed the idol and with a strength of gorilla, rhino and other animals, she started to smash it before tearing it to pieces.

Suddenly, Darhk lost his powers as he scowled, confused.

Glaring, Darhk rushed at Oliver as they exchanged blows, while Darhk knocked Oliver's bow out of his hand. Oliver dodged Darhk's kick before punching him. Snarling, Darhk grabbed Oliver by his arm and attempted to throw him down but Oliver grabbed onto Darhk as they both fell down. Oliver jumped up, attempting to kick Darhk but Darhk dodged Oliver's kick and kicked him in the chest, slamming him against a pillar as Oliver glared.

"Enough!" Oliver snarled before punching Darhk thrice in quick succession. As Darhk stumbled back, dazed, Oliver slammed him against the pillar where Oliver had been a moment earlier and drove an arrow into his heart.

"That was for my friends and my mom. And this one's for William, you son of a bitch." Oliver sneered, twisting the arrow and Darhk glared before Oliver let go and Darhk fell down, dead.

"It's over." Oliver sighed in relief.

Later, SCPD

Samantha hugged her son, relieved as Quentin assured her.

"Medics checked him out, he's in perfect health."

"Thank goodness, there's something you must have missed." Samantha showed him the Flash action figure.

"I'm kind of over the Flash, I want a Green Arrow action figure." William said.

"Well, the Green Arrow is pretty amazing." Samantha smiled at Oliver, who smiled back.

"Samantha." Oliver approached her. "You need to run. Run as far away as you can."

Samantha nodded.

Later, the Loft

Oliver was at the kitchen table, sitting in front of the laptop and turning on the camera he began speaking.

"Hi, William." Oliver said as he began recording his video message. "I hope you're well and I hope you're safe. There's something that I want to tell you, I wanted to tell you before but…this is better.

I'm your father. Biologically, that is. As far as really being your father goes, I haven't earned that yet. A father should be there for his child every day to make sure that they feel loved and that they feel safe. And a child should be able to rely on their father, to be able to go to him for guidance and reassurance. I have failed to do that for you.

And now I'm gonna tell you why: I'm the Green Arrow. And my life is very dangerous, which is why we decided to keep you out of it for all these years. What happened to you in Star City that was my fault. And I can' allow anything like that to happen again, which is why I've asked your mother to move you far away. And to not tell anyone where she's taking you, including me.

It's also why I've asked her to wait to show you this message until after your 18th birthday. I wanted to give you a real childhood; I wanted to give you that gift. Goodbye son, I sure hope it's not forever."

Oliver deactivated the web cam and sighed. Sara sat down beside him and a hand on his shoulder. He turned to her, looked into her kind, understanding eyes, and he came undone. The walls came down and Sara took him into her arms, hugging and attempting to bring him comfort as he broke down, grieving for the time lost with his son.

Later, H.I.V.E. HQ

"Mr. Darhk is dead." A member of H.I.V.E. said.

"A temporary setback." Ruve said. "We will continue…"

"…the cycle of violence. Admiring." A new voice said as a metal figure entered, speaking with mechanic voice. "But as much as I find this Genesis intriguing… I can't let you interfere with my work."

"Who are you?" Ruve demanded.

"I am… the one that gives humanity restart." The metal figure said before firing lasers, slaughtering the H.I.V.E. members.

I didn't do Moira stepping down as mayor, since frankly, hasn't Oliver learned anything from 4x09 with Darhk or Slade and Isabel Rochev in 2x18? Never agree to bad guy's demands.

Plus, as pointed out in Stand with Ward and Queen's now deleted story "The fate of the Green Arrow", one of the biggest disappointments about Season 4 is that Damien Darhk, the man, who had been built up as Ra's al Ghul's greatest rival and arch-nemesis, was a pathetic fighter without his magic, so I made him a capable fighter here.

And now we're going to jump to "Avengers: Age of Ultron". Finally! I've been looking forward to writing this part.

So, what do you guys think?
