Thank you to everyone who has favorited, followed or reviewed this fic so far.

Chaos Sorcerer: Thanks for the review. Glad you're not disappointed. Yes, the lovesick bitch got what he deserved. Glad it was good moment. Oh no kidding. Earth-2 was the worst idea, and with Jesse not being there (not that she could have stopped Savitar) it was even stupider. Yes, it is too ridiculous. If you think about it, Savitar was basically canon Barry. I can imagine him sitting next to Iris like a dog, with a collar and rope around him, making dog sounds, XD! Glad that gave you a good laugh and that is a great scene, thanks for that. Might just do it. Thanks for the Thor quote too. Oh Chase better run to his mommy. I have a nice plan for how to end him. And thanks for the review on 'Rest in peace young soul' too. It was a tragedy indeed. Also hope you check out the last 3 chapters of 'Smallville vs. Arrowverse' and 'She is not the one for you.' You'll love them.

Agent N: Thanks for the review. Glad you liked the story. I prefer Barry/Patty tbh but to each their own. The fan was right. Sorry, the joke won't make much sense here. We will see when I write it.

Guest: Thanks for the review. Sorry to disappoint. If you want epic, wait for the Crisis on Earth-X story.

Chapter 2- On Lian Yu

Arrow Cave

Oliver had finished convincing Malcolm to work with Nyssa when the elevator opened and out walked Thor and Kara as Oliver turned to face them.

"Oh you two!" Oliver sighed in relief. "Thank God…of Thunder."

Thor and Kara chuckled as the joke as Kara ended up hugging him, catching him off guard, though he appreciated it and hugged her back.

"For those of us who do not know them, who are these lovely new companions of yours, Oliver?" Malcolm asked.

"This is Thor", Oliver said as he pointed at Thor. "And that's Kara. On her Earth, she is known as Supergirl."

"Thor?" Both Malcolm and Nyssa gawked.

"As in the God of Thunder, is that right, husband?" Nyssa asked.

"Husband?" Kara asked as she looked between Oliver and Nyssa.

"Long story", Oliver muttered.

"And yes, I am the God of Thunder", Thor said as he raised Mjolnir, making Malcolm's and Nyssa's eyes widen in disbelief.

Asgard and its inhabitants were real? Was it the same for the other mythologies?

Getting over their shock, Malcolm asked Kara. "What makes you so super?"

Kara looked around, wondering how to reveal her powers, when she saw a dart lying on the ground. She picked it up and shattered it into pieces effortlessly, making their eyes widen again.

"That answers the question", Nyssa said.

Oliver walked to the two and said. "Thank you very much for coming. I appreciate it a lot. However…"

"What?" Thor asked.

"On the island, just to be completely on the safe side, I will be recruiting some more people", Oliver said. "But I am not sure who to trust. So until a situation calls for it, I want you two to hide your abilities."

"How will we know if we are needed to use our full abilities though?" Kara asked.

"You both have super hearing", Oliver said and they nodded. "So let's think of a code word or a phrase that would be considered a signal."

"For Odin, for Asgard", Thor said as they looked at him. "It's my war cry. Does that sound good enough?"

"Oh it works great", Oliver said gratefully. "Thanks a lot."

Later

The plane flew towards Lian Yu with Oliver, Malcolm, Nyssa, Thor and Kara in it.

"Why did your adversaries bring them here?" asked Nyssa.

"For that matter", Malcolm said. "How does he even know about this place?"

"Talia", Oliver said. "She researched me. Probably told Chase everything."

"Ironic", Nyssa said. "When I was a little girl, my father told me to visit this place. It's where I found Sara."

None of them noticed Malcolm's shocked expression on hearing that.

Thor and Kara looked down on the island, the place that had shaped this Oliver into the man he was.

Lian Yu.

A ninja took off the bag from Felicity's head and roughly pushed her to the ground. Her and John's hands were bound by cuffs along with Thea, Quentin and Curtis.

"Diggle? Felicity?" Curtis asked as he looked at them.

"We're fine", Felicity said.

"You ok?" John asked.

"We're fine", Quentin said. "A little north of pissed off though."

"Roy, Rene, Laurel?" John asked as he looked around, "Where are they?"

"Not with us", Thea said grimly.

Adrian then walked up to them, wearing his Prometheus suit minus the hood and mask. With him were Dinah Drake, Evelyn Sharp, China White, Carrie Cutter, Liza Warner and the entire army of Talia's League.

"Relax", he said with a smirk. "Enjoy the weather."

"Anybody tell you how much you suck at life?" Curtis asked when a ninja held a blade to his throat.

"No", Adrian said. "Care to be the first."

"Why are we here?" Thea asked.

"So you recognize this place?" Chase asked with a smirk. "That's good."

He then turned around and walked away with Dinah, Evelyn, White, Cutter and Warner following him.

As they walked off, Thea yelled. "Oliver is gonna come for us!"

"Yeah", Adrian said as he walked away. "I'm counting on it, sis."

"Damn it!" Dig said. "Chase is using us as bait. He wants to draw Oliver out."

"The numbers aren't exactly in his favor", Quentin pointed out.

"He's faced worse odds before", Felicity said optimistically.

"Yeah, with the help of you and John", Curtis reminded. "Roy and Laurel and Thea, and the rest of us."

"Curtis is right", Dig sighed heavily. "Oliver can't do this alone."

Oliver opened the door and slowly walked towards the cell with a duffel bag in his hand.

He dropped the duffel bag near the entrance and slowly walked towards the cell. He gave a sigh and said. "I need your help."

The man in the cell looked at him with his one eye and gave him a smile that seemed…..kind?

"Hey, kid. I'm glad you came back."

Slade Wilson got up and asked. "What brought you back to the island?"

"Like I said", Oliver said as he started unlocking his cell with his key. "I need your help."

"What the hell's going on here?" asked an ARGUS guard as he walked inside.

"We have a problem", Oliver said as he walked towards him. "And I need you to get off the island."

"I'm not going anywhere", the guard said before gesturing to Slade and saying. "And neither is he."

"I am taking him", Oliver said. "And I am taking Digger Harkness. There's an ARGUS supply boat that is docked on the eastern shore. You take it and you go."

"I'm not abandoning my post", the guard said dutifully.

Oliver felt respect for the guard for his sense of duty but he was an obstacle right now.

"Suit yourself", Oliver said and smacked him across the face, knocking him out.

He turned to see that Slade had used the key to unlock the door and come out.

"Would you like to explain what's going on?" Slade asked.

"I'd like to talk about you for a minute", Oliver said as he realized that Slade was different. "You seem-"

"What, in possession of all my marbles?" Slade asled with a smile and Oliver nodded. "The Mirakuru wore off a long time ago, kid."

Then with remorse in his eyes, he said. "I mean, I remember everything that happened. I'm not trying to escape that, but it feels like some bad dream. Now, regardless of my sanity, why do you want to help me, after everything that I've done?"

"There is a man here on the island named Adrian Chase", Oliver explained. "He's holding my friends and my family hostage, including Thea… and my son."

"Since when do you have a son?" Slade asked with a chuckle.

"Slade", Oliver, not in the mood for casual talks, said firmly. "Are you gonna help me or not?"

"I think I am stating the obvious when I'm saying that I killed your mother, and for that alone, you should have killed me", Slade said.

"Maybe what's happening now is the reason I didn't", Oliver said.

He then gave Slade a flash drive and said. "This is all the intel that I have been able to gather on your son, Joe, including his present whereabouts."

Slade seemed like he was about to break down due to the guilt inside him. The man whose mother he had killed was offering to help him find his son.

"Are you offering to help me find my son?" Slade asked as his voice cracked a little.

"I want us to find both of our sons", Oliver assured.

He then walked towards the bag and opened it, taking out an orange and black mask. It was Slade's Deathstroke mask.

Slade stepped back on seeing it as the last time he had worn it, he had done unspeakable things. Oliver handed it to him and he looked at it for some time.

"You and me kid", Slade said with a gleam in his eye. "Just like old times."

Thor and Kara were helping Malcolm and Nyssa offload the supplies as Nyssa said to Malcolm. "You know, if we're going to fight side by side, you're going to have to at least speak with me."

"I know, it's awful", Malcolm snorted.

The super couple looked between the two former League members as Nyssa scoffed. "Pity. By now I thought you'd realize that by disbanding the League of Assassins I freed us both."

"Are you looking for applause?" Malcolm asked as he raised his cybernetic hand. "Clapping is a little harder for me these days."

"Well, considering how bitter he sounds, he will probably never realize whatever it is you want him to realize", Thor said to Nyssa who smirked while Malcolm glared at him, though he knew that was the best he could do, as no way he was gonna even harm a strand of hair of the God of Thunder.

"What happened anyway?" Kara asked.

"Oliver cut it off", Malcolm simply said.

"And?" Thor prompted, knowing if Oliver had cut it off, he would have had a very good reason to do so.

"Malcolm took a position in the League he shouldn't have, because my husband gave it to him stupidly", Nyssa told the two. "Anyway, months later, his sister was dying and I had something that could cure her. But back then, I was very bitter too, so I held it back and asked Oliver to fight Malcolm for me. Oliver did and cut off his hand, which he deserved anyway, and after his sister was cured, I realized how petty I had been, so I burnt the Ring of the Demon and disbanded the League. No one has to be bound to an organization that was corrupted long ago."

"Well, I think we know who we like more out of you two", Kara shrugged as Malcolm sighed.

"Where did you two come from anyway?" He asked them, deciding to change the subject. "I know Team Flash and the Legends, never seen you two."

"Well, we helped out during the Dominator Invasion", Thor told him.

"And in return, Oliver and Flash helped us out against an enemy of ours", Kara said. "We've been good friends since then."

"And they are among the best people I know", Oliver said as he arrived with Slade Wilson who was now in his Deathstroke suit and mask with his sword strapped to his back and with them was also Digger Harkness aka Captain Boomerang, wearing his trench coat with boomerangs in it as he smirked.

"Have you offloaded the supplies?" Oliver asked.

"Most of them", Thor said.

"Guns and ammo are still on the plane", Malcolm informed him.

"By the way", Kara asked. "What do we need an RPG for?"

"Well", Oliver said. "Chase has Talia, an army of students, Evelyn Sharp, China White, Carrie Cutter, Liza Warner and a meta-human. I have no interest in this being a fair fight."

"What kind of meta?" Kara asked.

"The screaming kind", Oliver informed and she groaned.

"If only I had brought the devices Barry had whipped up", she muttered.

"Is that why you released the animals from their cages?" Nyssa asked as she eyed Slade and Harkness.

"Oh, come on, luv", Harkness said to her flirtatiously with lust in his eyes. "That is no way to start a new friendship."

"Look at me like that again and I'll feed you your eyes", Nyssa sneered as she walked up to him.

"You're not her type anyway", Malcolm said to Harkness.

"You sure about that?" Nyssa asked Malcolm who blinked.

"Really?" He asked. "Well that's it, I'm done helping you."

"I never asked for it anyway", Nyssa said as she glanced at Oliver before looking ahead.

"All right, that's enough", Oliver interrupted. "Let's offload the rest of the gear-"

"We have incoming", Thor said as he and Kara looked ahead at something.

"Where?" Nyssa asked.

Thor and Kara were about to do something when Oliver held up his hand. "Wait!"

They remembered what he had asked of them and stopped as the rocket hit the plane and exploded, destroying it.

"Hoo", Harkness said with a smirk. "So much for our gear."

"It's not like we needed it anyway", Oliver whispered as he glanced at Thor and Kara.

"There goes our ride home, kid", Slade said grimly.

"Another will come", Oliver told him before asking the two. "Is there anything else?"

"No, that was it", Kara said as she and Thor turned to him.

"Great", Oliver said as he opened a case that had his suit. "I'm suiting up and when I'm done, we'll go and take them all down."

"Can't wait", Kara smirked.

Thor, Kara, Oliver, Slade, Nyssa, Malcolm and Digger continued moving.

Thor and Kara suddenly sniffed the air around them and the latter said. "There are explosives here."

"On the entire island", Thor said.

"So that's what your nemesis has been doing in his free time, husband", Nyssa said and both Thor and Kara noted there was something about the way she said 'husband'.

"Why isn't he detonating them?" Oliver wondered.

"Well, he must have a reason", Kara said as she used X-Ray vision to look at the explosives. "Not that we will let him do it whenever he tries to."

Looking at his tablet, Oliver said. "The RPG that took out our plane came from over there. The call from my son originated just west of here."

"Hostages could be in either place", Harkness said.

"Or neither", Slade added before pointing out. "This is a large island."

"I'll check the RPG site", Malcolm offered.

"I'll accompany you", Nyssa said.

"Oh, its almost like you don't trust me, Nyssa", Malcolm said sarcastically.

"No", Nyssa said. "It's exactly like I don't trust you."

"Check it out", said Oliver. "Stay on comms."

He turned to Thor and Kara. "Please accompany them and stop them from killing each other."

"All right", Thor said as he and Kara led Nyssa and Malcolm away.

Oliver, Slade and Digger walked further with Slade in the front and the other two in the rear.

"Why does he get a weapon and I don't?" Digger asked as he gestured at Slade.

"I trust him more than you", Oliver said truthfully. Slade was like his brother before the Mirakuru. Harkness was just a psychopath who had tried to kill his friend- Lyla.

"Didn't he kill your mother?" Digger asked bluntly with a smirk.

"You listen to me very carefully", Oliver said as he gave Harkness a threatening glare and pointed his finger at him. "You help me take down Chase, you walk. You screw with me, even a little bit, and I will put you right back into that hole."

"Just a gun is all I'm saying", Digger shrugged.

Slade looked to a distance and saw some familiar figures.

"Kid", he called out. "I see movement."

Oliver and Harkness walked up to them.

They saw Thea, Felicity, Curtis and Samantha locked up in Fyers' old cages.

"Stay sharp", Oliver said.

The three ran over to the cages as nimbly as they could.

"Oliver!" Felicity said in surprise as everyone got up to look at them.

"Keep your voice down", Slade commanded.

"What the hell is he doing here?" Thea asked as she eyed Slade angrily.

"Where's William?" Oliver asked Samantha.

"I don't know", she said. "We were separated. Oliver, what is going on?"

"Why are they unguarded?" Slade asked.

"Seems pretty obvious to me, mate", Harkness said with a smirk.

Suddenly- Talia and Evelyn leapt down. As the three turned to face them, Talia aimed her arrow at them while Evelyn aimed a gun.

"It's a trap", Digger said.

"Don't even think it, Oliver", Talia threatened coolly as she aimed her arrow at Samantha. "Or your son loses his mother."

"Oh, and, don't worry about that gun, mate", Digger said as he took out a gun of his own. "Because Mr. Chase gave me this nice new one."

He then aimed it at Slade and said. "Along with a better offer."

"Adrian said it would be pointless to reach out to you", Evelyn said to Slade.

"Although given this turn of events", Talia as she eyed Slade. "Perhaps you've changed your mind."

"What's it gonna be Slade?" Harkness as he did not take his gun off him. "Care to side with the winners?"

When Slade didn't reply, he repeated. "What's it gonna be, mate?"

Pointing to Oliver, Slade said. "Put a gun to his head."

Oliver looked at him as he felt Thea's and Felicity's hateful glares and said. "Sorry kid. But there's no giving up to these guys."

Oliver recognized those words and realized Slade's intentions.

Talia and Evelyn smirked at how events had turned out for Oliver.

Oliver put his bow down while Evelyn walked over to him and put her gun to his head while Talia kept her arrow at Samantha.

Slade then walked over to Harkness who lowered his gun and said. "I assumed you'd want to be on the winning side."

Slade said to him. "Assumption, is the mother, of all failures!"

Slade then punched Digger on the face, making him stagger. As Evelyn was distracted, Oliver grabbed her hand and flipped her to the ground behind him, using the first move he had learnt from Slade.

Talia fired her arrow at Samantha but Oliver threw a fletchette just in time, deflecting it.

Digger punched Slade repeatedly on the chest but his armor protected him from the damage. Slade blocked a punch, hit him on the elbow, grabbed him by the back of the head and threw him to the ground.

Oliver picked up his bow and put a hand to his quiver, Talia doing the same.

"Sister!"

The two turned to see Nyssa and Malcolm with their arrows pointed at them, with Thor and Kara standing with them.

Thor and Kara were about to make a move when Oliver stopped them. "Wait!"

Talia and Digger exchanged a look before the former threw a flashbang grenade on the ground. It blinded everyone except Thor and Kara and when the smoke cleared, Talia and Digger were gone.

They opened the cages.

"You okay?" Malcolm asked Thea.

"Go to hell", she spat out.

"I'll take that as a yes", he said dryly.

Slade lead Evelyn to a cage and locked her in it.

"You have been left behind", he said. "You should choose your friends more wisely."

"I think I know why you didn't let us handle them", Kara said as she and Thor walked to Oliver.

"Harkness just betrayed me", Oliver said. "If he found out, we would have lost the element of surprise."

"Do you trust Nyssa, Malcolm and Slade?" Thor asked.

"Nyssa, I do, fully", Oliver said to them. "Malcolm, I wouldn't trust him at all normally but this is one situation where I would as it involves Thea. Slade, I am not sure. He hasn't betrayed me so far even when he had the chance, but I am still a bit cautious."

"It is a wise move", Thor assured.

"Where is everyone else?" Oliver asked the others.

"Not sure", Curtis said. "Chase split us up into groups when we got here."

"We're gonna talk about that, right?" Felicity asked as she pointed at Slade.

"Yes", Oliver said. ""We're gonna talk about that? Right now, we need to focus on finding the others."

He then walked towards Evelyn and asked. "Where are they?"

"I wish I knew", she said. "So that I could tell you all to go screw yourselves."

"So much hatred in one so young", Thor shook his head. "I wish I could say there was hope for you, but there truly is none."

"I'm done justifying myself", Oliver snarled at her. "You weren't my biggest fan even before the List. You sided with Chase because you think I'm the monster. But let me make this clear- you sided with him because you hold a grudge against me for your parents' deaths, and that blinds you to the fact that Chase is the real monster as he has killed many innocents. So you can rot in a cell with all that anger for all I care."

His piece said, he turned to the others as Evelyn actually looked stunned while Thor and Kara gave Oliver nods of approval.

"Why did Chase split up the hostages?" Merlyn asked her.

"Why does Chase do anything?" Evelyn asked back. "So far, he hasn't laid out a single hoop that you could keep yourself from jumping through. Maybe leaving me here was part of the plan."

"Keep telling yourself that to justify your poor life choices to yourself, kid", Kara rolled her eyes.

"How did Chase get you here?" Oliver asked everyone.

"A plane", Felicity said.

"You think you can find your way back to it?" Oliver asked.

"Yeah, probably", Curtis said. "But-"

"Malcolm", Oliver said. "Can you fly a plane?"

"If it is anything like the 3 Gulfstreams I used to have", Malcolm said. "Then yes."

"Get everyone to the mainland and then come right back for us", Oliver ordered and he nodded.

"We are no leaving you here!" Felicity protested.

"I need to focus", Oliver said. "And for that, I need to get you out of harm's way."

"Can I talk to you for a second?" Thea asked Oliver.

"Yeah", Oliver said as they walked to a distance.

Thor and Kara looked down and noticed a land mine.

"Since when have these been here?" Kara asked.

"Since a long time", Slade said. "Ever since Oliver and I met each other here."

"You two met each other here?" Thor asked. "When was that?"

"When he was stranded here", Slade explained. "I was with him for the first two years on the island."

"Why were you in a cell then?" Kara asked.

"During our second year, I was dying due to an attack and Oliver, Sara and a woman called Shado we both loved gave me a serum called Mirakuru to save me", Slade explained. "While I was recovering, Shado was murdered and Oliver kept from me how she died because he blamed himself. When I found out, I was enraged and due to drug's effects, I went mad and turned from his sworn brother to his sworn enemy. I did terrible things. I ruined Thea's innocence, and I killed Oliver's mother. But now….."

He trailed off.

"It feels like a bad dream", Thor said as he and Kara noted the shame in Slade's voice. "Because you two were like brothers once, Oliver is giving you a chance. I know the feeling."

"Are you speaking from experience?" Slade asked.

"Yes", Thor said. "My brother betrayed us all and my father died as a result of it. For a time, I thought he was redeemable but few months ago, he tried to kill everyone I cared about again, and that was when I realized there was no hope for him."

"I am sorry to hear that", Slade said.

"Even I have experience in that area", Kara said. "My first big enemy was my aunt who wanted to save the Earth in her own twisted way. We managed to take her down, but in her last moments, she died to protect me. So if she could come around, I am giving you the benefit of the doubt."

"Thank you", Slade said as Oliver and Thea returned from their chat.

"My sister and Harkness fled into the forest", Nyssa said as she returned. "But I can track them."

"They might lead us back to the rest of the hostages", Slade said.

"They're our friends and we don't need your help", Felicity protested.

"I see you haven't lost your feistiness, Miss Smoak", Slade commented mockingly.

"Get them to the plane", Oliver said to Malcolm before turning to Thor and Kara. "Make sure everyone stays safe."

They nodded, understanding his reasoning. While he said he trusted Malcolm in this situation, he clearly didn't trust him fully. And if Malcolm decided go rogue, Curtis won't be able to do a thing, while Thea would put up a small fight before he took her down.

At least in Oliver's case, if Slade went rogue, he had Nyssa by his side and he clearly trusted her fully.

Walking to them, he whispered. "For Odin! For Asgard!"

Thor nodded as understanding passed between them.

Oliver gave Curtis comms. "Comms, in case something goes wrong."

"You mean "when", right?" Curtis asked and Oliver realized he was right.

Oliver gave Felicity a tablet and said. "Detailed imagery of the satellite. Thor and Kara say there are bombs all over. Again, just in case."

She was just about to kiss him when Nyssa grabbed Oliver and turning him to her, kissed him passionately on the lips. Oliver was a bit shocked at first but then he realized he liked it and returned her kiss.

The others watched with agape jaws, while Thor and Kara snickered very lightly so no one could hear them.

Felicity looked hurt, while Slade simply looked amused.

The two parted as Nyssa. "I just wanted to know."

"What?" Oliver asked.

"If you felt the same way about me, husband", Nyssa said.

Oliver smiled and said. "We will see where this goes once this is over."

Nyssa nodded as Oliver turned to the others, turning professional again. "You all keep each other safe."

With that, they parted.

And that ends it.

I know no changes yet but I am saving them all for next chapter.

Once again, thank you to WritersBlock039 for some inspiration and scene ideas.

As for Olyssa, I like the pairing but I haven't written for it yet, until Phillipe363 suggested I could do the pairing in this story, and he wasn't wrong, so thank you to him. And if you're gonna argue she is a lesbian, well, this is fanfiction, where straight characters are made gay, so you're only gonna make yourself look like hypocrites.

Evelyn is one big hypocrite and she deserved everything she was made to hear.

Hope everyone enjoyed and see you all next time with another chapter. Until then, stay safe from the coronavirus ya all!
