Oliver and Kara face down Chase, and the race is on to find Oliver's son. Also, once again, apologies if anyone is out of character. If you can't tell, this was written way before the Season 6 premiere, so yeah, things are obviously going to get quite AU when I reach the current seasons. I regret nothing, though.


Oliver Queen

"Where is my son?" Oliver asked Chase angrily.

"I love this," he chuckled. "Even now at the end, you're still ten steps behind."

"Where is my son?"

"William? Good name," Chase remarked to Black Siren, who smirked. "Sort of a sweet kid, actually. You sure he's yours?"

"Adrian!" Oliver snapped, walking forward. "Where is my son?!"

"If you want to get your son back," Chase walked forward, narrowing his eyes. "You know what you have to do."

"I know what you want me to do," Oliver shook his head. "And I won't do it. I'm not gonna kill you. No matter what you do, that is never going to happen." In the back of his mind, he was wondering where the hell Kara was, but then, as if it was an afterthought, he heard the pounding of boots running behind him . . .

"Never say never," Chase smirked, raising his sword to charge.

He had barely gotten one foot in front of the other when twin beams of blue-white hit the ground in front of him. He let out a shout, jumping back as the beams traced a line just in front of his men, Black Siren scrambling backwards as well. "What is this?" Nyssa demanded, even as John's eyes widened, and he started laughing in pure relief. "Husband, what is this?"

"Ten steps behind?" Oliver smirked at Chase. "Are you sure about that? If you'd been ten steps ahead, you would have known exactly what those words meant. El mayarah? It's not an Earth language. It's alien." He looked behind him. "And so is she."

Kara finished drawing the line with her heat vision, turning back to look at him, floating in the air. He could count on one hand the number of times he had seen Kara angry. Now, she just looked pissed off. "Hopefully, I'm not too late," she told Oliver as she slowly descended.

"No, Kara," he shook his head, turning back to Chase, who was staring at Kara with wide eyes. "You're right on time."

"Good," Kara walked forward to join him, ignorant of the startled looks she was receiving from Oliver's team, save John and Rene, who had met her before. Even Slade found it hard to look away from her. "Because, you know, I just had to double check and make sure I didn't hit any of his bombs when I was on my way over."

Oliver threw her a sharp look. "What?"

"Oh, he didn't tell you?" Kara tilted her head, smiling sweetly at Chase, seeing him turning a vivid shade of red. "He's buried bombs all over Lian Yu. Did you know, I actually thought they were landmines? Yeah, that was until Thea stepped on one, Malcolm pushed her off, and I narrowly saved him from getting blown up. You won't hear from Harkness again, he's dead." Oliver slowly turned to look at Chase, narrowing his eyes, tightening his grip on his bow. "A word of advice, Oliver," Kara bent her knees, preparing to pounce. "Don't kill him until we know exactly what the detonator is."

"Kara, I like your thinking," Oliver nodded, turning to Chase, narrowing his eyes. "I just have one question."

"Mmhmm?"

"Can you share what those words mean?"

"Oh, el mayarah?" Kara grinned. "It's the words of House El. It means stronger together."

With that, Oliver charged forward, Kara right on his heels. Chase barely got his sword up in time to block the downward slash from Oliver. Then he had to spin around and narrowly dodge the punch Kara threw at him, only to then keep blocking Oliver.

From then, it was chaos, as Black Siren ran at Dinah, Slade bursting past her to slice through more of the assassins. John, Nyssa, Rene, and Quentin engaged the other assassins, Nyssa using her sword to bring them down, John and Rene resorting to hand-to-hand.


Dinah Drake

Black Siren had forced Dinah down the hallway, the two metahumans throwing punches and kicking each other, trying to get the upper hand. Dinah finally tossed Black Siren to the floor, then screamed at her.

Black Siren countered with a scream of her own, the two cries throwing them away from each other. Black Siren collapsed at the foot of the stairs, Dinah groaning as she crashed into the wooden shutters behind her.

Black Siren got to her feet first, Dinah still wincing as she tried to get up. "You thought you could replace me?" she demanded, then laughed coldly. "That's cute."

She opened her mouth to scream again, but Dinah blinked when a wooden staff smashed into her head, knocking her to the ground. Dinah panted, looking at Quentin, who was looking down at Black Siren. "You didn't have to do that," she said.

"Oh, I did," Quentin nodded. "For so many reasons."

Dinah just smiled and accepted his hand when he helped her up.


Thea Queen

"Oliver, do you copy?" Curtis tried the comms once again.

"Are you sure you can't defuse these bombs?" Samantha asked Felicity.

"Well, I can with my equipment back in Star City, but with this teeny, tiny, little tablet, all I can do is try and locate the trigger," Felicity nodded.

"OK, but you can try, right?" Thea asked.

"Yeah, I can try!"

"OK," Thea nodded, taking deep breaths. "Good. You do that, and then, Curtis, you just – you work on the comms, OK?"

"How?" Curtis frowned.

"I don't know," Thea shook her head. "You're the genius, all right? You both are, so we need you to do this, so you guys just got to both do this right now."

Felicity and Curtis exchanged nods, then went to work. "Hey," Malcolm put his hand on Thea's shoulder. "Look, I get that you want to stay – "

"Damn right, I do," Thea growled.

"Well, if you're not going to trust me, then trust Kara," Malcolm told her firmly. "Do you really think she and Oliver are going to let these bombs go off?"

Thea closed her eyes. "No," she admitted.

"No, she won't," Malcolm shook his head. "I don't know what she's told you, but I talked to her when we made it here. She's not going to let a single person die if she can't help it." Thea bit her lip and nodded, and Malcolm looked up. "If you can hear me, Supergirl, it would really be nice to get off this island before these bombs blow!"


Kara Danvers/Oliver Queen/John Diggle

"Then why didn't you go?" Kara seethed, then launched at Chase. She grabbed him by the collar of his jacket, soaring onto the next level. She threw him to the ground and landed, running at him. Chase's eyes widened, and he hurriedly ran at her, bringing his sword down on her. Kara grabbed his wrist and flipped him into the air, right at Oliver, who had made his way up after her. Chase stumbled, then swung at Oliver, bow and sword clacking as they hit each other.

Kara watched them go at each other, then took another look at the battles going on below her. She narrowed her eyes, then shot her heat vision, burning the sword hand of the assassin about to stab John. He cried out, and John flipped him to the ground, looking up and nodding at her in thanks. Kara nodded back, jumping up onto the railing, looking to see what else she could do to help. Quentin and Dinah came running back from wherever they were, nearly running straight into a wall of assassins. Kara flew down and blew hard, freezing their feet to the ground. The assassins shrieked, distracted enough to allow Quentin and Dinah to take them out.

She heard punching from above, and she turned in midair to see Oliver had punched Chase against the rail. "There's the killer I know and love!" the man grinned.

"Tell me where my son is!" Oliver yelled, punching him again, causing Chase to go over the rail and collapse on the floor, Oliver jumping down after him.

Kara quickly ran to block Chase's way, wanting more than ever to take him out herself, but this man had ruined Oliver's life. It was up to him what to do with Chase. So when he jumped down and put Chase in a headlock, she didn't stop him. "Do it, Oliver," Chase grunted. "I know you want to!"

"Yeah, OK," Oliver spat. "Adrian, tell me! Tell me where my son is!"

"Never!" Chase growled. Kara looked behind her, hearing the sounds of swords diminishing. "It's all over, but only if you do it," Chase told Oliver as everyone else started crowding behind Kara. "Do it, Oliver, and show everyone. Show yourself who you really are!"

Oliver grimaced, struggling against Chase, when he saw Kara's head tilt to the side. She blinked, then held out a hand to stop the others from moving forward, running off down the hall. Before she vanished from view, she turned back to Oliver, and he paused, seeing the confidence she had in her eyes. That he would make the correct decision, that he would know the right path to take.

It was that trust that made up his mind. "No!" he roared, taking the gun Chase had and knocking him to the ground. Chase collapsed, gasping for breath, and Oliver tossed the bullet in the gun to the floor. He tossed the gun aside and turned around. "That's who I was. That's who I was before! It's not who I am now." He looked down at Chase, who was still curled up on the ground. "You can blame me for your father's death for the rest of your life. I am done blaming myself for mine."

He turned to go, then heard Chase cackle behind him. "I knew it would come to this. Your son is dead, Oliver!"

Oliver froze, turning back around. He heard Dinah gasp behind him, heard Slade exhale as he took off his mask. He heard the sound of footsteps behind him, but he ignored them, grabbing Chase and leaning in close. "I don't believe you because you're a liar," he growled. "You're lying to me to manipulate me into doing what you want, but Adrian . . . here's the thing. If you are telling the truth . . . if you killed my son . . . I am never going to be the person you want me to be. Not ever."

He threw Chase to the ground, then stood up when he heard Felicity over the comms. "Oliver? Oliver, do you copy?"

"Felicity?" he asked.

"You can't kill Chase. Did you hear me?"

"What are you talking about?"

"He's rigged the entire island with explosives."

"Yeah, Kara told me."

"But they're remotely linked to some sort of dead man's switch. If he dies, it detonates all the devices. He wants you to kill him so it kills all of us." Oliver watched Chase as he rose to his feet, a sick grin on his face, then made a throwing motion at the ground. Oliver quickly ducked, the explosion knocking him to the ground. "Oliver!" Felicity cried. "Oliver, are you OK?"

"It's OK, I'm fine," Oliver gritted his teeth, looking around angrily. Chase had disappeared. "I'm fine."

"I know where he's going," Kara said, and he turned to see Kara walking back . . . and she was supporting Black Siren. John tensed, but Kara shook her head. "She told me."

"Chase brought William a different way," Black Siren wheezed, looking up at Oliver. "I didn't know he was bringing an innocent kid."

"Chase has a boat he's holding William on," Kara told Oliver. "If I leave now, I can make it there before him."

"Go," Oliver ordered, and Kara nodded, balancing Black Siren before taking off, smashing through the windows and out into the open air. He turned to Black Siren, who was taking shaky breaths. "If I find out you are lying," he growled.

"I'm not," Black Siren shook her head. "If Chase dies, we all die. I don't want to die today. I don't want to be controlled by him any longer. Zoom, Prometheus . . . they all just wanted me to be their pretty little attack dog." She sighed. "You asked who I was. I want to try and find that person again."

Oliver looked past Black Siren to see the hopeful look in Quentin's eyes. "Then you'll go with them," he told her. She simply nodded, and Oliver walked up to John. "You need to get to the plane and make sure that everyone's safe. Felicity can talk you in."

"Oliver, what the hell is going on?" John frowned. "Not with William, but – ?"

"You heard Kara, Chase has put explosive charges all over the island," Oliver answered. "You need to get to the plane, and you leave when you get there."

"What are you gonna be doing?" Rene asked.

"Kara may get there first, but I'm going after my son," Oliver answered.

"Chase knew how to get in Oliver's head," Black Siren said. "William's alive. I saw him not that long ago."

"And with Kara's help, I'm going to make sure Adrian Chase does not get off this island," Oliver said firmly, running for the exit.

"Someone want to tell me who the hell that was?" Quentin looked around.

"That?" John smirked. "That was Supergirl."

"And if that kid's hurt, she's gonna kick Chase's ass all the way back to Oliver," Rene snickered.

"Then let's hope she finds him," Nyssa turned to head out.

"Yeah," John whispered as he followed. "I hope so, too."


A/N: Next chapter, everyone on the island finally gets back together, and Oliver and Kara face off Prometheus one last time.
