Disclaimer: I do not own Arrow.

So, we're not going to cover episode 4x11. This is because it was a very Diggle and Andy centric episode, so not a lot would have changed. Also, this does not cover all of 4x12. I originally planned t o but I don't like cutting back to the same setting, which this would've done, so I stopped t there. The next half of the episode should be up sometime this week.

Starling General Hospital

Morning

"So, you're ready to get back out in the field?" Oliver asked a hint of worry in his voice as he and Thea got ready to leave the hospital.

"Dr. Green said everything checks out, I'm good to go. Stop worrying Ollie." Thea chided as she put on her jacket.

No sooner had the words left her mouth than Thea swayed on her feet. She started falling and Oliver's trained reflexes were the only thing that allowed him to catch Thea.

"Or worry." Thea said feeling lightheaded.

Arrow lair

Afternoon

"You're sure she's alright?" Laurel asked worriedly after Oliver had told them everything.

"I don't know. I took her home to rest." Oliver sighed.

"What do you think is going on with her?" Sara asked and Oliver sighed again as he ran a hand over his face.

"I wish I knew, I really wish I knew." Oliver said tiredly.

Oliver's penthouse

Later in the afternoon

"Thea," Oliver waked in but was surprised and alarmed to see Malcolm in his home, "I just wanted to see how you were doing."

"I think the answer to that is fairly obvious," Malcolm began, "Thea's bloodlust is the balancing of an equation. Thea was given life and now she needs to take it."

"We know that alright," Oliver said, annoyed by the man's very presence, "what we don't know is why-"

"What you don't know," Malcolm said as he stood up, "what I didn't know until Thea collapsed is that, if the life doesn't come from taking others, it will come from the life of the host."

"Please don't refer to me as the host." Thea grumbled.

"This isn't a joke Thea. If you don't indulge this bloodlust, you will die!" Malcolm shouted.

"I don't understand, Sara isn't like this." Oliver said confused.

"John Constantine made Sara whole and restored the balance." Malcolm told him.

"I thought you were doing better." Oliver said as he looked over at his sister.

"Because the bloodlust was temporarily blunted." Malcolm explained.

"By what?" Oliver demanded, noticing the guilty look that crossed Thea's face.

"Damien Darhk," Thea said and he looked at her stunned, "when we rescued Andy from Hive, I ran into him. He tried to use his magic death touch thingy on me but it didn't work."

"What it did was stop the bloodlust," Malcolm sighed, "for a time."

"Why didn't either of you tell me this?!" Oliver demanded.

"You keep secrets all the time." Thea said defensively.

"To keep you all safe! This is your life Thea!" Oliver shouted and Thea winced. "We need to find Darhk and make whatever he did to her permanent!"

"Oliver, even if that were possible, if you caught Damien Darhk in his most cooperative mood, Damien Darhk has gone to ground. Or haven't you noticed." Malcolm asked and Oliver lost his patience.

"This is all your fault," Oliver snarled as he stalked over to Malcolm, "if you hadn't drugged her and made her kill Sara, none of this would be happening!"

"Ollie-" Thea began but Oliver ignored her.

"The only reason you're even alive right now is because Thea cares about you beyond all reason and logic! And I swear to god, if she dies, I will kill you!" Oliver shouted at the stoic Malcolm.

"You're phone is ringing." Malcolm said blankly.

Sneering, Oliver dug out his phone and answered.

"What?" He growled.

"Well hello to you to. Our sticky fingered friend just pulled another job at Cadmus Tech." Laurel told him.

"Laurel, I can't right now." Oliver said, not wanting to leave Thea.

"He stole a weapon this time." Laurel said and Oliver froze.

"Just go," Thea said weakly, "Nothing is gonna change here in an hour."

"I'm on my way." Oliver said after a moment.

Star City

Night

"Where am I looking?" Oliver asked on the phones.

"We're working on it." Diggle said as Oliver looked up and saw a cloaked man running across a rooftop.

"Got him!" Oliver shouted as he hung up.

Oliver raced after the cloaked man on the ground and used a car as a stepping stone to get onto the roof. The figure jumped of a rooftop and Oliver followed him. They jumped off a few rooftops until the figure landed on a large shipping crap. He jumped off it and ran as a truck pulled op. Oliver jumped, landing on the top of the truck before hanging on as the truck moved. The figure continued to run but the truck kept pace with him as he ran into a junk yard. Oliver jumped off the truck and into the junk yard before giving chase once more. As the figure fled, Oliver used some pieces of junk to boost himself up and intercepted the figure on the fence. Oliver pushed the figure off and the figure landed on a closed dumpster before bouncing off, landing hard on his back on the ground. Oliver jumped down to the ground, grabbed the figure, and yanked the lower part of his mask down to reveal-

"Roy?" Oliver gasped in shock.

In response, Roy slugged him. Taken by surprise, Oliver let go of Roy and Roy punched him in the abdomen before running off. Oliver staggered to his feet and stared after his former protégé in shock.

Arrow lair

Later

"First Sara, then Ray, then John's brother, whose surprising return shall we look forward to next week?" Felicity asked dryly.

"Oliver, I'm just gonna ask this to make absolutely sure," Diggle began, "are you sure-"

"It was Roy," Oliver interrupted him, "absolutely."

"Or maybe it was someone that can make themselves look like Roy," Laurel said and they all looked at her, "Don't act like it's the craziest theory after all we've seen."

"What's crazy is Roy stealing from tech companies." Oliver said pointedly.

"What did he take now?" Sara asked as she looked over at Felicity.

"Triode capacitor bomb. Tiny device, really huge bomb." Felicity explained as the others exchanged grim looks before Oliver's phone went off.

"It's Alex for the five-hundredth time today." Oliver grumbled as he turned and walked off.

Star City

Later

After learning that Ruve Darhk, going by Ruve Adams, was going to run for mayor, Oliver knew what he had to do in order to save his sister. Ruve walked out of her office when she saw Green Arrow waiting for her.

"I want to arrange a meeting with your husband." He said in disguised voice and Ruve smirked.

"I'm not sure you would survive another meeting with my husband." She mocked.

"Not to fight, I have a proposition for him," the archer said and Ruve was intrigued, "Tomorrow, 10:30. Kershaw and Eighth."

With that said, Green Arrow turned and walked away.

Arrow lair

Same time

"So what have you figured out?" Sara asked as she, Laurel, and Diggle stood behind Felicity.

"Well, it's not good. If Roy could put the two pieces of tech he stole together, then he could essentially create a wed nuke." Felicity explained.

"Like a bomb?" Diggle asked alarmed but Felicity shook her head.

"No, worse. Something that could destroy the internet. I'm taking bank accounts, Power grids, you name it." Felicity said and alarm grew.

"Okay, last year, Ry could barely spell computer and now this? It doesn't make sense." Laurel said confused.

"What I want to know is why Roy hasn't set it off." Sara said.

"Because it's incomplete. He needs one more thing before he can do that. Guess where it is?" felicity asked dryly.

Palmer Tech

Later

Roy had just knocked out Curtis when the glass behind him shattered. Roy whirled around to see Green Arrow and, to his shock, The Canary standing before him. Hearing footsteps, he looked over his shoulder to see Spartan and Black Canary, all of them aiming their weapons at him.

"Roy, stand down." Green arrow ordered.

"There's something wrong with him." Felicity said over the comms.

"No kidding." The Canary muttered.

"Let's talk about this Roy." Green Arrow told him.

Roy, wait what are you doing?" Black Canary asked before Roy threw the ball in his hand.

It went out the shattered window, going just over Green Arrow's shoulder. They looked outside and saw whatever it was get picked up by a drone that flew odd.

"Okay, you need to listen to me very carefully." Felicity said over the comms before telling him her plan.

"Are you sure?" Green Arrow asked.

"Yes." Felicity said.

Green Arrow notched an arrow before firing. It hit Roy in the chest and he fell back, seemingly dead as the others stared in shock.

"What did you do?!" Spartan demanded.

Arrow lair

Later

"Put him down," Oliver ordered as the reentered the lair, carrying the unresponsive Roy, "take out the tranq, carefully."

"Let's hope the faraday cage Cisco installed works." Felicity fretted as they put Roy down

"What?" Sara asked confused.

"A device that shields everything electronic," Oliver said and saw the looks he was getting, "Waller had one. Which eye did you see the tech in?"

"The right one." Felicity said and Oliver went after it

He opened Roy's eye and saw something on it. Oliver carefully picked it off Roy's eye and handed it to Felicity.

"How'd you know he had it?" Diggle asked.

"Roy's eyes are blue. I'm guessing this was sending an AV signal, probably to whoever was picking up the tech." Felicity noted as she examined it.

"Well, he can tell us when he wakes up." Oliver said as he pulled out a syringe.

Oliver stuck it in Roy's leg and injected it into Roy. As he pulled it out, Roy gasped as he came to.

"Where am I?" Roy demanded as he sat up.

"It's okay." Diggle assured him.

"We took out the contact, made it look like we killed you. You're safe." Oliver assured him.

"While I'm in here at least. New lair, nice," Roy noted before he looked at Sara, "and you're not dead, also nice. I'm sure that's a hell of a story."

"You have no idea." Sara said dryly.

"Roy, what happened to you?" Diggle asked him and Roy sighed.

"I got made. I was in Hub City, new name, new life, everything. Then I got an email." Roy explained.

"Saying what?" Laurel asked as she crossed her arms.

"To do whatever he said or he'd expose me as Roy Harper. Suddenly The Arrow's not dead, and then the police would be looking at you. Again." Roy said as he looked right at Oliver.

"Who's blackmailing you?" Oliver asked.

"I don't know, I've never met him. But he calls himself The Calculator." Roy said And Felicity chuckled, muttering something about bad guys and names.

"Roy, you should have come to us sooner." Oliver told him.

"I couldn't." Roy said.

"He's right, there's a built in camera in here. This is really incredible tech." Felicity said sounding almost admiring.

"He could see every move I made, every person I talked to. I couldn't just expose you guys like that." Roy said.

"We would've figured something out." Oliver argued.

"This was my problem." Roy defended.

"Because you were solving my problem." Roy didn't have a defense for that.

"Well, our problem is that The Calculator now has everything he needs to melt the internet." Laurel pointed out.

"Which means we better find him quickly.

"Felicity, back trace the components and figure out where it broadcasts to." Laurel ordered.

"Take off your jacket, I'll patch you up." Oliver told Roy.

"I cannot believe you shot me." Roy smirked.

"Really?" Oliver asked and the two chuckled.
