The Mirakuru army was tearing the city apart, alongside the Ninth Circle's operatives.

In SCPD, one of the men wearing Deathstroke masks threw Hilton aside as the other officers tried to shoot him down. Another officer tried to hit him with a nightstick but the soldier threw him away like a ragdoll.

"Everybody down!" Quentin shouted as he pulled a pin from a belt of grenades and threw it at the soldier, while the remaining officers took cover, the explosion killing the soldier as debris flew around.

"It's like these things are not even human." Hilton muttered.

"Because they're not." Quentin said, already suspecting what they were. "Guys. Look, forget about what you've been taught. Shoot to kill. Aim for their hearts, their heads, it's life or death. Don't try to take them in, you'll only get yourselves killed."

"Quentin…" Pike tried to protest.

"This isn't about upholding the law anymore, this is about surviving!" Quentin said. "These things are monsters. And it takes monsters to stop monsters." He pointed out, citing Taiana as everyone realized who was he talking about.

"You want to rely on the vigilantes?" Pike demanded.

"The Arrow." Quentin corrected. "Lieutenant, I know he's breaking the law but what we're up against, it's not about the law, it's about survival. We got masks tearing our city to pieces and we're going to need a mask to stop them."

Pike considered for a moment before sighing. "Make the call. And considering you know more about what's going on over everyone else I got, I need you making decisions and leading these men."

"What about the National Guard?" An officer inquired.

"The mayor has called them already." Pike said.

"They might not make it in time." Quentin pointed out.

"Oliver. Oliver, do you copy?" Felicity called out.

"Talk to me, Felicity." Oliver said.

"S.T.A.R. Labs called. They have a cure. Not sure if it's enough to stop Slade's army but there's a courier en route." Felicity said.

"Where is it?" Oliver demanded.

Oliver, Sara, Roy and Nyssa were at the driveway as they saw the S.T.A.R. Labs van upside down.

"Are you OK? Are you hurt?" Oliver asked before they saw the courier bruised and beaten up, with the briefcase cuffed to his wrist.

"Could've been worse." The courier groaned.

"We need to get out of here." Sara said as they saw Slade's men and the Ninth Circle's soldiers approach them before the League's assassins appeared, shooting at them.

"We need to fall back." Oliver said as he, Sara, Nyssa and Roy retreated, while the League was trying to cover them.

"We'll buy you enough time to retreat." One of the assassins said as Oliver, Sara, Nyssa and Roy ran off.

The Lair

Felicity and Diggle heard banging.

"What was that?" Felicity demanded before two men in Deathstroke masks appeared. "Oh, frak!"

Diggle pulled out his gun and fired but the Mirakuru soldiers were unfazed.

Starling City

"Aaaaaagh!"

"Felicity!" Oliver shouted.

Diggle and Felicity ran out, with the Mirakuru soldiers chasing them before the League's assassins descended from above, shooting at the soldiers in the head and in the hearts.

"Are you alright?" One of the assassins asked and Felicity nodded, freaked out. "You need to get somewhere safe."

Later, clock tower

Oliver stared at the city in flames. "How are we supposed to win? I've been trying to right my father's wrongs and yet our past keeps coming back to haunt us. Emiko. Slade. All I ever wanted was to save my city and I couldn't have imagined something like this was possible."

"What's happening now isn't your fault." Felicity said.

"Maybe not. But no matter what I do, they keep winning." Oliver said, leaving, Diggle, Roy and Felicity sad that they still were unable to reach him, alongside Sara. "I tried to honor my father. Yao Fei. Shado. But…"

"You honor the dead by fighting." Felicity pointed out. "And you are not done fighting! Malcolm Merlyn, the Count, the Triad, everyone who's ever tried to hurt this city, you stopped them! And you've beaten worse odds before! And you will stop Slade and Emiko."

"I don't know if I can." Oliver sighed.

"Neither do I. But what I do know is that you are not alone. And I believe in you." Felicity said.

"No matter what happens, we're with you until the end of the line." Diggle said.

"For five years you were on your own but not anymore. We're in this together, Oliver." Roy said.

"How do we know the cure is going to work?" Oliver asked as Felicity opened the briefcase.

"There's only one way to find out. But what they sent us might not be enough to stop Slade's army." Felicity said.

"As long as we use it on Slade and it works, it doesn't matter." Oliver said.

"We only have just a couple of shots. No mistakes." Sara said.

"Orders, Al Sah-him?" One of the assassins asked.

"Put them down. Permanently." Oliver ordered.

Starling City

The assassins started to hunt the Mirakuru army, cutting heads off, shooting them in the hearts or heads and killing the Ninth Circle's soldiers.

Roy and the assassins fired arrows and Helena fired crossbow bolts, shooting down the Ninth Circle's men before the assassins pulled out blades, engaging the Mirakuru soldiers and slicing their heads off. Roy rolled away as one of the Mirakuru soldiers slammed his fists to the floor and jammed the injection arrow with the cure into his chest before knocking him out. Helena dodged as one of the Mirakuru soldiers attacked her and kicked him back. The soldier threw her away but Helena grabbed a rebar and impaled it on his head.

Nyssa flipped back as two of the Ninth Circle's men attacked with Kukri knives. Nyssa blocked with her bow before she hit one of them in the face and kicked another one in the leg. Nyssa pulled out her sword and stabbed one of them in the chest before finishing off the other one.

Oliver and Sara dodged as one of the Ninth Circle's operatives rushed at them. Oliver kicked him in the leg, as he fell on his knees before Sara grabbed him in neck lock and snapped his neck.

"Where's Slade and Emiko?" Sara snarled. "Tell me and I'll make it quick."

Oliver suddenly got a call as he tapped his earpiece. "Hello?"

"You've been busy, big brother."

Oliver glared. "It's over, Emiko. Your and Slade's army is broken. Your men are being beaten. You've lost."

"And we pity them." Slade called out. "But once again, you miss the point. I have the ones you love. You're going to meet me where I say. Otherwise, I'm going to kill him."

"I'm done playing your games!" Oliver exploded.

"You're done, when I say you're done!" Slade roared. "It was smart, to send your family and friends away but you're not the only one with many resources. I'll admit, you've grown smarter and they're quite slippery. Your mother… and your son."

Slade smirked as the Circle's operatives brought in terrified Moira and William.

The Arrow and Canary snuck into old factory as they were lurking in the dark.

"Twitch and I will open your throat." Slade's voice echoed throughout the factory as the Arrow notched an arrow. "My first words to you, do you remember? I do. I remember the exact moment. My blade against your neck. Just like my blade is against the neck of those most dear to you. If only I'd killed you then, everything would be different."

They neared Slade and Emiko as Slade had the sword against William's throat.

"Drop your weapons." Slade ordered. "Do it."

They both reluctantly complied as they heard Moira trying to fight back as another one of Slade's lackeys dragged her to the scene. "Yes, countless nights dreaming of taking from you all that you took from me."

"By killing those he cares about the most? The ones he loves?" Sara asked.

"Yes." Slade said.

"Like you love Shado." Oliver murmured.

"Yes." Slade replied.

"You see her, don't you?" Oliver realized. "Well, what does she look like in your madness, Slade?" Slade put William on his knees as they glared at him. "What does she say to you? I remember her being beautiful. Young. Kind. She would be horrified by what you've done in her name."

"What have I done?" Slade growled, putting the sword away from William for a moment as the boy breathed out, terrified. "What I have done is what you lack the courage to do! To fight for her! So, when their bodies lie at your feet, their blood wet against your skin, then you will know how I feel!" He roared, glaring at both vigilantes.

"We already know how you feel." Sara said.

"We know what it's like to hate, to want revenge." The Arrow continued. "And now we know how it feels to see our enemy so distracted… he doesn't see the real danger is so close to him."

Slade and Emiko were completely perplexed before Diggle shot Slade from behind with a dart with the cure. Slade cried out in pain as he pulled the dart out of his neck.

"Kill them!" Slade ordered.

Before either Slade's or Emiko's men could make a move, Helena, Diggle, Nyssa and Roy appeared, shooting them with the cure and taking them out.

"Get them out of here!" Oliver ordered as Helena, Diggle, Nyssa and Roy accompanied William and Moira out.

"This isn't over yet." Emiko sneered.

"This ends here!" Oliver snarled.

Slade lunged at Oliver with his sword but Oliver blocked with his bow and parried Slade's attacks before he kicked him in the chest as Slade fell through the window. Slade got up and swung his sword but Oliver dodged Slade's attack. Slade kicked Oliver in the hip as he fell on his knees. Oliver blocked again as Slade struck with his sword but Slade kicked him in the chest as Oliver stumbled back.

Sara dodged as Emiko fired an arrow. Emiko raised her bow, blocking Sara's attacks with her sticks.

"You've joined him? Let me show you how he destroys everything around him." Emiko said.

"I've only seen you destroy everything around you." Sara sneered.

Sara jumped back, while Emiko attacked with her bow. Emiko threw a pair of knives but Sara blocked them with her batons. They both exchanged blows before Sara kicked Emiko in the midsection as she fell down. Emiko recovered and jumped at Sara, wrapping her legs around her and knocking her down before both girls got up.

Slade ripped Oliver's mask off as he glared.

"The Mirakuru isn't what made me hate you!" Slade snarled. Oliver dodged as Slade swung his sword before he grabbed Oliver by his throat as they turned to see Sara and Emiko fight. "This ends tonight, kid. But maybe I'll be merciful enough to let you live long enough to watch her die again!" Slade roared as he lifted Oliver into the air.

Sara and Emiko exchanged strikes with their weapons before both women clashed with their weapons as they were knocked away and they started to fight in hand-to-hand combat.

"This isn't going to change what happened." Sara said.

"As long as the Queen's legacy is worth nothing, I'm fine with it." Emiko said.

Sara grabbed Emiko's hand as Emiko attempted to stab her with her knife. Sara knocked the knife off Emiko's hand and elbowed her in the face and punched her in the chest, knocking her back. Sara blocked Emiko's punches before kicking her in the leg as Emiko fell down. As Sara attempted to finish her off, Emiko wrapped her legs around Sara's arm and flipped her, knocking her down.

Oliver freed himself from Slade's grip as both men exchanged blows before Oliver dodged as Slade attempted to cut his head off. Slade kicked Oliver in the back but Oliver again dodged Slade's blade and hit him in the stomach. Oliver and Slade got up and spun around, Oliver again blocking Slade's sword before he kicked him in the chest as both men fell down, exhausted.

Both Sara and Emiko recovered and rushed at each other. Sara blocked with her batons as Emiko fired arrows and knocked her down. Emiko again tried to attack but Sara dodged and hit her in the back as Emiko fell over the railing down below and Sara sighed in relief.

"We both know that there's only one way that this can end." Slade said as both him and Oliver got up on their feet. "To beat me, kid, you're gonna have to kill me. But in the moment of my death, you'll prove one thing. That you are… a murderer."

Slade roared as he and Oliver rushed at each other and Oliver kicked him, sending him off the roof down onto the ground. As Slade landed on his back, Oliver descended from above.

Slade got up on his feet and Oliver threw a punch but Slade dodged and hit Oliver in the face, then he punched Oliver again before rushing at him with his sword, aiming at his heart but Oliver blocked the sword and knocked Slade against a concrete pillar before firing two bola arrows, restraining Slade.

"You can kill me, or not." Slade said tiredly. "Either way, I win."

"I am going to kill you… but not because I'm a killer. Because you're a monster. And I'll stop you, whatever it takes." Oliver said before he jammed an arrow into Slade's throat as Slade gagged, blood pouring from his neck and mouth. "You can blame me for Shado all you want… but I am done blaming myself. Goodbye, Slade."

Slade glared and breathed out at the man, who had once upon a time been his brother before he tilted his head and drew his last breath and light left his eye and Oliver's eyes got wet. Oliver closed Slade's eye, mourning for the friend and brother Slade had been on Lian Yu.

"Ollie." Sara said and Oliver turned to her as she limped towards him, bruised and bloodied before she saw dead Slade restrained to the pillar. "Is he…"

"It's over, Sara. It's over." Oliver said, hugging her tightly before they saw Emiko, bleeding out and limping.

"You've won…" Emiko said as they turned to her, surprised she was still standing. "You've beaten Slade. You've stopped my men. They turned their backs on me. They've retreated." She fell down on her knees, stretching her arms. "Do it. Finish it, brother."

"Emiko…" Oliver whispered, surprised she had a death wish.

"I'm never going to stop coming after you. No prison can keep me. You know that. Come on! Kill me!" Emiko urged.

"No!" Oliver shouted as he dropped his bow and pointed at Emiko, glaring. "I'm not going to kill you, Emiko. Not because I don't want to but God knows I want to kill you! But you don't get to destroy who I am! I'm never going to give you or anyone else the satisfaction that they're right about me! You're going to live the rest of your life in a cage, away from everyone else, knowing that this city, my family rejected you! It beat you! I BEAT YOU! It's over, Emiko! You've lost!"

Emiko seethed, glaring as Oliver and Sara were about to leave. Emiko pulled out a knife and rushed at Oliver before a gunshot rang out.

Oliver and Sara both whirled around and saw Emiko frozen before blood poured from her chest and she fell down, dead as they saw Moira with a gun in her hand.

"That was for Robert." Moira whispered.

As much as my feelings about Felicity are mixed, admit it, her speech to Oliver about not done fighting is one of her best moments. Plus, remember, in this they had few days to make the cure and in the show it was 2-3 weeks, if I'm correct, so they had just a few shots to stop Slade, not an entire army.

And I doubt Mirakuru could heal a headshot or shot in the heart, since Cyrus Gold got put down, when the ceiling fell down on him.

And I might get some flak for killing Slade off but I've already established in "The Journey of the Hero" that Future Slade wanted them to kill him. Plus, let's be honest, the only reason Oliver spared Slade in the show was because of Tommy's death and that did not happen here and as much as I liked redeemed and reformed Slade in Seasons 5-6, despite that the time travelers knew that Slade could be redeemed, would they really risk him living, even if he was cured?

And originally, I wanted Emiko's ending to be like Slade's in the show, ending up in prison on Lian Yu but after watching Crisis on Infinite Earths, which royally pissed me off, I did not want to bother with her. And frankly, my opinion on Oliver killing Emiko is mixed. On one hand, she is an irredeemable monster for letting Robert die but on the other hand, I'm not sure I want Oliver to have the blood of his own sister on his hands and besides, if anyone else than Oliver deserves to kill her, it's Moira and Thea.

One or two more chapters to go.
