An idea I had a while ago after reading Aragorn II Elessar's stories, just got around to writing it. Was originally a one shot, but I split it up into two parts because it flowed better that way. Hope you all enjoy it.

Arrow lair

Night

Oliver Queen was in his lair, as Felicity and Curtis liked to call it. He was looking at the suit display, specifically his sister's old Speedy suit when the back of his hair stood on end. He wasn't alone, he realized. Hearing someone drop down behind him, Oliver pulled out a flechette and threw it at them.

The intruder caught the flechette, stopping it inches from their face as Oliver stared in shock at who it was. It was another man wearing a Green Arrow suit.

"Who are you?" Oliver demanded immediately as he grabbed Thea's katana and pointed it at the man. "How do you know about this place? And why are you dressed like me?"

"What's the matter Ollie, don't recognize me?" the man said with a laugh.

Oliver frowned in confusion before the man pulled back his hood. Oliver almost dropped the katana in shock as he stared at the man's face.

"T-Tommy?" Oliver stammered and Tommy Merlyn smiled sadly.

"Yes and no. I am Tommy Merlyn, just not the one from this earth," Tommy said and Oliver stared at him for a moment as he realized what Tommy was saying.

"You're from another earth," Oliver said lowly and Tommy nodded.

"Earth-2 to be precise," Tommy said and Oliver breathed lowly.

"And on this Earth-2, you're the Green Arrow," Oliver noted and Tommy nodded.

"About five years after you and your father were lost at sea, he was found on a deserted island," Tommy explained.

"Lian Yu," Oliver muttered and Tommy nodded.

"Some things don't change, no matter what earth," Tommy said with a dry grin before he continued. "Not long after, reports of this 'Hood' began showing up. There was this new drug going around The Glades, Vertigo. I swear, I thought I was watching her, I thought I had handled it."

"Handled what?" Oliver asked although a sinking feeling entered his chest as he saw the pain in Tommy's eyes.

"Thea, she took your death hard, harder than anyone. She got a hold of some Vertigo on her eighteenth birthday and…she overdosed," Tommy said his voice and eyes full of pain and guilt.

Oliver swallowed thickly, grief hitting him like a ton of bricks. It wasn't his Thea, but it was still Thea. Oliver walked over to Tommy, who flinched like he expected to be punched. Oliver reached out and, to Tommy's surprised, placed a comforting hand on Tommy's shoulder.

"It wasn't your fault Tommy. I'm sure you did everything you could. Some people, you just can't put back together after they break," Oliver said, his voice thick with emotion.

Tommy swallowed thickly, looking at Oliver with unshed tears as he felt a huge weight lift from his shoulders.

"What happened next?" Oliver inquired after a moment of silence.

"I went looking for The Hood. I wanted to track down the low lives that had sold Thea the drugs, who were still selling the drugs to kids just like her, and make them pay," Tommy said. "That's when I found out it was your father."

"If he was The Hood, how did you end up becoming the Green Arrow?" Oliver asked, not at all surprised by this turn of events.

Tommy smiled unpleasantly and Oliver got a pit in his stomach. Clearly, there was no lost love between his parallel father and Tommy.

"He trained me, taught me everything he knew, then we started going after the dealers, they all worked for someone named The Count. About seven months after Thea died, we went after The Count. I put an arrow in his chest but not before he gave your father an enhanced dose. Your father, he brought back these special herbs from the island, I used them to make sure he didn't OD like Thea. While he was detoxing, he hallucinated that I was you. That's when I found out what really happened to you," Tommy said and Oliver had a sinking feeling. "He always said you drowned, that he was the only survivor of The Gambit, but that was a lie. You both made it to the life raft, but he realized that only one of you would survive. So he pulled out a gun and shot you."

Oliver was silent as he processed this. It was what he had expected to be honest. Still, it was disconcerting to find out that another version of his father had killed him.

"What happened then?" Oliver inquired.

"I turned him into the police, after making sure your father couldn't link me back to his crimes. Once he was arrested, I became the Green Arrow. To honor Thea's memory, not for him" Tommy explained and it was silent for a moment.

"Then that only leaves one question: why are you here, on my earth?" Oliver demanded.

"Laurel Lance," Tommy said and Oliver smiled. "What?"

"Like you said, some things never change, no matter what earth," Oliver explained amused.

"Not like that. After you died, she went off the deep end. After she got her powers, she was rounded up with the rest of the Metas, experimented on by an organization called Argus," Tommy said and Oliver tensed. "You know them?"

"You could say that," Oliver said darkly.

"After she joined up with Zoom, I spent a long time trying to take her down. It took me until now to track her here, to your earth," Tommy explained. "Imagine my surprise to find out the Green Arrow on this earth was the doppelganger of my best friend and that I was dead here."

"I can imagine," Oliver said dryly. "So looks like we have a common enemy."

"Looks like it," Tommy noted. "So what's the plan Ollie?"

Before Oliver could answer, an alarm sounded from the computer. Oliver quickly raced over to see what was wrong.

Star City

Later

Oliver and Tommy rode onto the scene on motorcycles. As they got off and removed their helmets, Oliver frantically looked around for Diggle and Felicity but only found an overturned car.

"John! Felicity!" Oliver cried out.

"Your friends aren't here Oliver," Tommy said gently.

"Damn it!" Oliver said in frustration.

"From what you've told me of Chase, he would have taken them alive. You have to focus Ollie," Tommy told him. "Is there a way to track them?"

"I had tracking Nanites in Felicity, but they were rendered useless when Chase set off an EMP," Oliver said regretfully.

"Well, I'll give him this, Chase is at least fifty moves ahead of us," Tommy noted. "But what's his endgame?"

"He wants to leverage me into breaking him out of prison," Oliver explained and Tommy was silent for a moment.

"And our sister's life isn't sufficient leverage?" Tommy asked incredulously as he walked up behind Oliver.

"Do you really think that Chase is gonna hold up his end of the bargain Tommy?" Oliver demanded as he whirled around to face him.

"Okay, fair point," Tommy said after a moment. "But there has to be something we can do."

"A little while ago, I was worried that the personal connections that I had were making me vulnerable because as long as there are people in my life that I care for, I have to be something else to protect them. That's something I can't leave in the past," Oliver explained and Tommy was silent for a moment.

"That is…really stupid Ollie," Tommy said and Oliver looked at him annoyed.

"I am in no mood Tommy," Oliver grumbled as he stalked passed Tommy.

"Human connections are what make us human," Tommy said and Oliver paused. "I tried to shut my father and your mother out after I became the Green Arrow, but it didn't take. We are always going to have people in our lives, and they will always need us, for better or worse, baggage and all. And if you can't accept that, your past is going to stay your anchor."

Oliver considered Tommy's words before his phone rang.

"Yeah?" Oliver said as he answered.

"Mr. Queen", the man on the other side said. "The Marshals are here to transfer the prisoner. You said you wanted to know."

"Thank you", Oliver said. "I'm on my way."

He hung up before he turned to face Tommy.

"We are very capable people. And we are gonna find a way to rescue everyone," Oliver said before he got on his bike, put on the helmet and drove away while Tommy watched.

Argus base

Later

Oliver fought the Marshals frantically after seeing the video call where he found out Chase had taken his son William. As three more surrounded him, they were suddenly hit by arrows and went down. Oliver looked up to see Tommy standing on a bridge in his own Green Arrow suit.

"Let me guess, he took someone important to you?" Tommy asked.

"How'd you know?" Oliver asked.

"It's what I'd do," Tommy said honestly before dropping a duffle bag at Oliver's feet. "Come on, we can still catch them."

At the transfer sight, The Marshals were escorting Adrian to the chopper as it landed.

"Something funny, nutbag?" One of them asked on noticing Adrian's smirk.

"Not yet," Adrian as he looked at them. "But soon."

As they continued escorting him, there was an explosion behind them and they started running.

"See what I mean?" Chase asked the Marshal with a smirk.

When the smoke cleared, an arrow flew out of it and hit a Marshal's gun, disarming him. Oliver, wearing his black mask and armed with his bow and quiver, and Tommy ran out of the smoke. Oliver and Tommy fought of the Marshals, taking them out with ease as the group at the front attempted to get Chase to the chopper. Oliver fired an arrow, which landed in front of the remaining Marshals and Chase.

"We're compromised, take out the prisoner," one of them said over the comms.

The arrow exploded and sent all but Chase to the ground. One of the Marshals followed the new orders and tried to shoot Chase from above. Chase avoided his shot and it hit his cuffs instead, freeing him.

"They're targeting Chase," Oliver realized.

"Go, I'll cover you," Tommy promised.

Oliver nodded in thanks before running after Chase. Tommy fired arrow after arrow, incapacitating the marshals shooting at Chase as Chase ran for the chopper. He took out the Marshal standing guard over it as Oliver ran after him.

"Chase!" Oliver roared.

Chase turned around as Oliver reached him, grabbing him by his shirt and slamming him, back against the chopper.

"Thanks for the assist pal," Chase said cheerfully.

"Where is my son?!" Oliver roared.

"No, no! That wasn't the deal, Oliver. That wasn't the deal. I said, you let me go and I'd keep your loved ones safe, but I'm not gone yet," Chase told him.

Oliver let him go after a moment and removed his mask, looking at Chase brokenly.

"Why did you involve William? That's my boy. He's an innocent," Oliver said emotionally.

"So was my wife man. But you involved her," Chase said pointedly. "I already told you, Oliver. Everyone that you care about suffers. Everyone."

Chase then turned and got into the chopper.

"I'll see you on the boat," Chase said before he closed the door.

Oliver narrowed his eyes in confusion as he watched the chopper take off, watching it until it disappeared from view.

Arrow lair

Later

"Chase's helicopter flew to an abandoned airfield in Dawn Valley, Utah. Then, five minutes later, this aircraft took off from the same field at a vector of two-seven-zero," Oliver told Tommy as they tracked Chase's movements on the lair's computer.

"Due west. That would take him back to Star City. Chase seems smarter than that," Tommy noted.

"He is. He turned off the transponder on the plane. Luckily, Felicity has access to a keyhole satellite which can track the heat signature of any aircraft in the world," Oliver explained.

"Cool," Tommy whistled, impressed before a beep went off. "Expecting someone?"

"Yes. Chase is working with at least Talia al Ghul, Evelyn Sharp, and your Laurel Lance, plus Talia's students," Oliver said and Tommy nodded.

"So you called in back up, smart. Who'd you call?" Tommy asked curiously.

Tommy's answer came as the elevator opened and an exotic beauty walked out.

"Husband," Nyssa al Ghul said to Oliver in greeting.

"Husband huh? I'm sure that's a story I'll love," Tommy said jokingly and Oliver lips twitched.

"It's a story for another time. Tommy, meet Nyssa al Ghul. Nyssa, this is Tommy Merlyn of Earth-2," Oliver introduced them.

"Ah Ghul? As in…" Tommy trailed off as he saw the look on Oliver's face. "Oh."

"Oh?" Nyssa raised an eyebrow. "What is going on Oliver?"

"One of the people Chase is working with is your sister," Oliver said gently.

Nyssa was visibly surprised by this. Oliver wanted to say more but, at that moment, the computer started beeping, having Chase's location.

"We have Chase at C-one thirty," Oliver said as he raced to the computer. "He flew over the coast, baked southerly twelve degrees, which means…which means…"

"What does it mean?" Nyssa asked when Oliver's voice failed him.

"I know where he's taking them," Oliver said lowly.

"Where?" Tommy asked and Oliver didn't answer. "Ollie, where is he taking them?"

"Lian Yu," Oliver finally managed to say. "He's taking them to Lian Yu."

Got this idea after reading Aragorn's story 'Green Arrows unite'. Some of the dialogue and words were taken from his story with his permission, although I did change it a bit. Thanks buddy.

Earth-2 Adrian being the Green Arrow was a nice twist in 8x01, but I feel they missed a great opportunity not to have it be Earth-2 Tommy. Plus, Tommy as the Dark Archer was a little predictable.
