Disclaimer: WB/DC own these characters. I'm only borrowing them for a while. I own the original ideas found in this.

AN: Thank you for returning to this story. I hope you have been enjoying it, and leaving me reviews, which would make me happy. This is the last chapter of this story, but I do have a sequel, of sorts, in the works. See bottom AN for more details.

And, I know I just posted Ch. 3 just hours ago, but I am anxious to hear what you think of this as well. And hopefully next time I am near the internet, I can post my sequel!

Previously:

"I am truly sorry, Liege. I realize I brought disgrace to the League, both through the Undertaking, and through Ta-er Sa-fir's murder." He swallowed, trying to muster all the sincerity he could. "All I want is to return to your good graces, to become your horseman once again."

"Good try, Al Sa-her, good try. I wish I could accommodate you, but, you see, Al Sa-her," Ra's said, approaching Malcolm, "I do not believe you." He followed his statement with three swift punches to his abdomen, then to his kidneys. "Such transgression, Magician," several more punches to his jaw and face, "cannot be forgiven." A final punch to Merlyn's nose, causing a major nose bleed.

Face bloody, talking through a split lip, Merlyn mumbled, "I would do anything for you, Liege."

"Nice offer, but a little too late," Ra's said, using Merlyn's abdomen as a punching bag. "Like you have heard me warn others, Al Sa-her, you should have been careful not to make me angry."

As punches continued to rain upon his battered body, Malcolm struggled to retain consciousness, but eventually he lost the battle.

Ra's al Ghul looked in disgust at the beaten man hanging unconscious in front of him. He shook his head, walked out of the cell, and gave his soldiers orders to take the prisoner down. Wishing to make the agony last as long as he could, Ra's would allow Merlyn a day or so to rest, then would continue the torture.

Looking at the broken man, Ra's wasn't sure how long he would last. Overall, the man ended up being a disappointment all around. He had shown such promise when he had first arrived in Nanda Parbat, broken over his wife's death and the city's supposed betrayal. Perfect building blocks to form the type of soldier the League of Assassins needed. And he was. Until one day Ra's discovered he had an ulterior motive for joining the League, and never truly intended to be a true member of the League. Malcolm Merlyn only wanted to learn the secrets of the League then use them to supposedly avenge his wife. Which, to Ra's, was the ultimate betrayal.

So, unluckily for Al Sa-her, his time to face justice had now arrived. And knowing what Ra's was capable of only made it worse for him, Ra's was certain. The halls of the Fortress rang with the laughter of the leader of the Assassins.

Several months later, Laurel and Oliver were in the Arrow Bunker. Oliver finally had relented and begun teaching Laurel some fighting skills, which they were reviewing this night. Dig and Roy were out patrolling, and Felicity was manning the comms.

"Busy as always, I see." A voice no one had wanted to ever hear in the Lair ever again floated in the air.

Oliver quickly grabbed his bow and quiver near him, notched an arrow and aimed at Nyssa's heart. Laurel held her bo-staff tightly in a defensive stance, and Felicity pressed a silent alarm for Diggle and Roy to return to the Bunker. She also turned the comms on in the Bunker, so Roy and Dig could hear what was going on.

Oliver demanded in a cold, even tone, "What are you doing here, Nyssa?" He looked around and didn't see any other LOA soldiers accompanying the League Heir but didn't relax his guard. Catching Felicity's eye, she nodded slightly, letting him know she had hit the silent alarm.

Nyssa held up her empty hands in a gesture of surrender. "I do not mean any harm."

"This time," Felicity mumbled.

Nyssa continued as though Felicity hadn't interrupted her, her eyes remaining on Oliver. "I have brought news about Ta-er Sa-fir."

"How dare you mention my sister's name after you injured my friends," Laurel demanded, stepping up in line with Oliver. Oliver tried to motion her back, to keep Laurel behind him, but Laurel ignored him, keeping her eyes on their uninvited guest. She was determined not to allow this…this… betrayer harm her friends this time.

"I refuse to apologize for our League ways. Laurel, I did what I had to do to bring justice for the woman we both loved. In the end, I believe you will be satisfied with the final results."

"Why don't you just tell us why you are here and take your leave," Oliver said.

Nyssa acknowledged Oliver's anger and began to pace in front of them. "I simply wish to inform you Al Sa-her is dead. As a result of League justice. He finally succumbed to injuries last night brought on by my father's torture." Looking at Laurel, Nyssa added, "You can rest assured, justice was indeed gotten for Sara."

"It might be your ways, but we usually don't get our kicks from someone else's torture." Looking at Oliver, Laurel said, "However, if there was ever a case I would make an exception, it would be this one."

"There is one remaining item I need to tell you, Oliver." Nyssa stopped her pacing and looked at the archer, who remained focused on her every move, the bow never leaving its target. Every instinct was hyper-vigilant, his body prepared for a fight if necessary. "I hesitate to tell you this, but to bring this entire affair to its proper end, I feel the need for full disclosure." She paused once more, capturing everyone in a sweeping glance.

Losing patience while waiting for Nyssa to continue, Oliver demanded, "Well, go on then!"

"Merlyn indeed was not the one to deliver the fatal blows to my Beloved, but he was the one behind the deed." She allowed her statement to be heard by her stunned audience.

After a moment, Oliver asked through clenched teeth, "Then who was it?"

"If I may approach the computers?" Nyssa asked. Felicity looked at Oliver, who reluctantly nodded, and gave a nod of her own to Nyssa, who gave Felicity a flash drive. Felicity grimaced, examined it, then put it in a slot, waited for it to be checked out by her computer security as she leaned back in her chair.

"Laurel, Oliver, can you please come here so you can also see the screen?" Nyssa requested.

Oliver reluctantly lowered his bow, nodded to Laurel, and they took places behind Felicity, who punched up the one video on the flash drive. They proceeded to watch a scene they would never have guessed. It showed Thea, Oliver's own sister, wearing a veil covering her head and lower part of her face, and a black fighting outfit, approach Sara in her Canary outfit, shoot three arrows into her chest, then turn around to walk towards the camera. Her eyes appeared blank, her face emotionless. No other sound could be heard.

"What? What is this, Nyssa?" Oliver exclaimed.

"Oliver, I'm going to play it again," Felicity said as she set it up again to play. The three watched again in silence as the video played once again.

Oliver turned to Nyssa. "What is the meaning of this…this video, Nyssa, and where the hell did you get this from?"

"The only reason I brought you this, at the risk of causing you and Laurel more pain, was for you to know the whole truth regarding how and why Sara died and who was ultimately responsible."

"My sister? My baby sister who grew up idolizing Sara supposedly killed her? This must be a fake," Oliver said, attempting to tamp down the anger which was threatening to explode. All he wanted to do was reach out and snap Nyssa's neck. He flexed both his hands into fists, his knuckles turning white.

Nyssa stood her ground under Oliver's dangerous glare. "Thank you, Oliver, for allowing me to explain this. Malcolm was secretly training your sister all summer in Corto Maltese, as well as drugging her with an ancient herb known as Votura."

Oliver became reflective. "Votura? Isn't that a League of Assassin tool?"

Nyssa nodded. "Yes, Malcolm had become well-acquainted with it during his years with the League. He set up your sister up to kill Ta-er Sa-fir."

Oliver numbly reached for an office chair and sat down at the end of the computers. He rested his elbows on his upper thighs, covering his face with his hands, he could only shake his head. Looking up, running his hands through his hair Oliver quietly asked, "Why?"

"According to what he had told my father, Malcolm thought it was the only way to get the blood debt off of his head. By setting up Thea, he would force you to battle Ra's. Either you would kill Ra's, setting both him and Thea free from any and all blood debts, or you would be killed, Ra's would consider the blood debts satisfied as part of the result of a duel, and Malcolm would be free in either case."

"That no-good SOB," Felicity mumbled.

At that moment, Dig and Roy burst into the Bunker and ran down the stairs. Even though they had been listening, and Nyssa apparently not a threat, Dig still had his gun aimed, and Roy his bow ready. They stopped at the bottom of the stairs, in fighters' stance, waiting for a sign from Oliver. At a shake of his head, both put down their weapons and walked slowly towards the group.

"Wouldn't have thought you'd have the gall to return after what you did to Oliver and Felicity," Dig said to Nyssa.

"I was hoping my news would make some amends," Nyssa said.

Diggle remained silent but shook his head slowly.

"So in the end…." Nyssa began.

"If you say, it was just business and no hard feelings, think again, lady," Diggle said. He took a step towards Nyssa, but Roy placed a hand on his arm.

"Okay, understandably we will not agree on whether my actions were warranted in the end. Neither will I apologize for them. However, I thought you should know, and use the knowledge as you wish. Al Sa-her had hoped, at the end, to use the tape as a means to escape justice and involve you, Oliver, and your sister once again. I wanted to inform you that my father sees no reason for that to occur. He understands your sister's actions were not made of her own free will, and it only added to the injustices Al Sa-her ended up paying for with his suffering and life."

Nyssa took a step back from the group. "I will now take my leave. My father and I consider this to be the closing of all business between the League and all of you. Hopefully, we will not cross paths again."

She looked at Oliver, who solemnly nodded. "Thank you, Nyssa. We will consider this matter closed as well."

The Arrow team watched as the Heir of the Demon took her leave. As the door latched behind her, Felicity said, "Whew! Glad that's over!" She jumped as though she had surprised herself with her statement, and looked over at Oliver. "It is over, isn't it, Oliver?"

"I hate to say it, but I am really glad Merlyn is now dead," Laurel said, collapsing into a chair. "Proving to be a real SOB up to the very end, trying to get Oliver to do his dirty work for him." Letting a loud 'humph' escape, she added, "And to top it all off, trying to escape justice at the very end by trying to implicate Thea anyway."

"A real winner indeed," Felicity mumbled.

"I wonder if we should've asked Nyssa for proof of death, like his head on the end of a spear or something," Roy said.

Oliver shrugged. "One way or another, he is dead. So…back to business." Looking at Roy and Dig he asked, "Any concerns regarding the patrolling tonight?"

As he listened to his teammates, Oliver couldn't help but think about his sister. He knew he needed to tell her about Malcolm being killed, and why. He also knew he would have to address with Thea all those unanswered questions regarding why she had kept her training with Malcolm a secret from him. As well as breaking the news to her about who really killed Sara. However, he needed time to absorb all of it, and figure out a plan.

Catching Laurel's eye as she made her way gradually closer to the men to be included in the conversation, Oliver knew he also had his hands full with integrating Laurel fully into the team. Knowing her stubbornness, Oliver knew once she had decided to become part of the team, it really was useless for him to object, knowing it was only a matter of time before Laurel would become a part of the crime-fighting team.

With both his sister and former girlfriend, Oliver knew he had his hands full indeed. Luckily he didn't have to worry about a vengeful head of assassins anymore. One less worry indeed. As he had told Diggle months ago, anyone tangling with the Head of the Demon courted death. He returned his attention back to the Team and pushed all the other thoughts aside for the moment to finish their tactical conversation.

AN: Well, that's it then. The truth about Sara out, Merlyn dead. No further action from Nanda Parbat. No silly story about trying to make Oliver Heir. Hmm. Hope you enjoyed this little adventure. It was sure fun to write. Even though it kinda ended season 3 canon in four or five episodes. Ha.

The sequel I mentioned? Will focus on Lauriver, since the ILY in the Arrow Lair, the duel, and Oliver leaving for Nanda Parbat never happened in this universe. So that leaves open the very real possibility for Laurel and Oliver to get closer. (much more than a possibility). I hope you will check it out when I post the first chapter. Thanks again for reading this story.
