"How?" Oliver asked, just to have Tommy give him the silent treatment.
"DAMN IT TELL ME HOW THIS HAPPENED?" Oliver shouted at him.
"Death is just another prison, you of all people should know that." Tommy said.
"Your father brought you back using the Lazarus pit didn't he?" Oliver asked.
"No, you see, my father had no idea that the pit could actually do that, otherwise he would've brought my mother back to. No I was brought back by another Lazarus pit in the possession of a woman. She brought me back and trained me to become your worst enemy." Tommy said.
"Who did this?" Oliver asked.
"I thought that move I pulled back at the plant would've told you. After all we had the same teacher." Tommy said.
"Talia." Oliver said and Tommy nodded.
"Why would she do this?" Oliver asked.
"Because 2 years ago you killed her father, just like how you killed mine." Tommy said.
"Your father never gave a rat's ass about you." Oliver said.
"Maybe not, but he was still my father and you lied to me when you told me you let him live." Tommy said.
"What did you mean when you said I killed Talia's father?" Oliver asked.
"Think about it? Who was the only person you killed 2 years ago." Tommy asked and Oliver's blood ran cold.
"Talia's father was Ra's al Ghul." Oliver said.
"Yes, and then to add insult to injury, you inadvertently caused the destruction of the League of Assassins." Tommy said.
"Tommy, Talia is just using you to get to me." Oliver said.
"No, I'm doing this for me to. For years, you were always treated better than I was. You took everything from me. You took the woman I loved." Tommy said.
"I never took her, you let her go. You have no one to blame for that but yourself." Oliver said.
"Maybe, but then you couldn't help yourself could you. And she is just as much to blame for what happened to me as you are." Tommy said.
"If you so much as lay a hand on Laurel, I'll kill you myself." Oliver said.
"You already did that." Tommy said.
"Tommy please, I am begging you, come back." Oliver said.
"Oh, I don't think so Oliver." a woman's voice said as a face Oliver hadn't seen in 5 years approached him.
"Talia, what the hell did you do to him?" Oliver demanded.
"Different Lazarus pits have different effects on those who use them. Tommy's was a blank memory." Talia said.
"You brainwashed him into your servant." Oliver realized.
"The perfect instrument of my revenge. Someone I know you will never hurt." Talia said, just to have Oliver raise his bow at her.
"You're going to tell me how to free him right now." Oliver told her.
"No, I don't think I am. Attack." Talia said.
"Yes mistress." Tommy said as he unsheathed his sword and lunged at Oliver, who barely caught the strike with his bow.
"I don't want to hurt you Tommy." Oliver told him.
"Don't worry, you won't." Tommy assured him as he swung at him.
"Oliver's been gone too long. Should we worry?" Rory asked.
"Relax, with Oliver we give it a full week before we start worrying about him." Laurel said.
"Well, there's no need to worry, because I'm back." Oliver as he entered the base and he looked more shaken up then they'd ever seen him.
"Oliver, did you find out who Prometheus is?" John asked.
"I did." Oliver said.
"Well, don't keep us waiting in suspense. Who is it?" Rene asked.
"It's Tommy. Tommy Merlyn." Oliver said, tears in his eyes.
"Wait, who?" Rene asked.
"Oliver's best friend. He died 4 years ago in the Undertaking." John said, since Oliver and Laurel were both in too much shock to answer.
"How?" Laurel asked him, her voice threatening to break.
"Nyssa isn't the only daughter of Ra's al Ghul out there. She has an older sister. Talia al Ghul. She has her own Lazarus pit, which she used to bring Tommy back and she corrupted his mind." Oliver said.
"It sounds like you knew this Talia?" Rene said.
"I met her 5 years ago when I was in Russia. She taught me a lot of what I know." Oliver said.
"So why would she turn on you like that?" John asked.
"Because apparently she liked her father a lot more than Nyssa did." Oliver said.
"That's what this is about, you killing Ra's?" Laurel asked.
"Yep and Talia has turned Tommy into the instrument to get vengeance." Oliver said.
"Um, would you mind cluing us in?" Rory asked, referring to himself and Rene.
"2 years ago the head of this organization called the League of Assassins named Ra's al Ghul attacked his city in the Outbreak. I ended up killing him. And it appears that Talia what's revenge." Oliver said.
"So your actions are literally coming back to haunt you." Rene said.
"Now is really not the time." Laurel growled.
"Yeesh, what's your problem?" Rene asked.
"Tommy is Laurel's ex and it didn't end well." Oliver explained.
"Oh." Rene said.
"Yeah, so we can try and figure out how to get Tommy back?" Laurel asked.
"Get in contact with Nyssa. We'll need her help. And it's clear that Thea and Quentin will not be safe here, especially with Thea being in her current state." Oliver said.
"I'll get her out of the city." Roy said.
"Good, I don't care what you do, but I will not let my little sister or your kid become collateral damage in this fight." Oliver said.
"Do you really think that Tommy would kill his own sister?" Laurel asked.
"Tommy never knew that Thea was his sister." Oliver reminded him.
"Just another reason to put a bullet in this guy's head then." Rene said.
"Wait what?" Oliver asked Rene.
"This guy's a mass murderer. He's killed tons of innocent people." Rene said.
"While under some kind of mind control. I failed to save Tommy once before and I refuse to have to live with that pain again." Oliver said as he walked out of the bunker.
