Oliver, Digg, and Roy were standing nervously in the elevator at Stark Tower. When they'd contacted the Avengers to warn them about Nyssa's threat, tony had insisted that Team Arrow come to New York. The doors opened on the top floor and they stepped out into an enormous penthouse. Tony and Thor were standing behind the bar debating the merits of Asgardian Ale vs Scotch. The rest of the Avengers were in the middle of the room around a holotable.

"Oliver! John! Roy!" Felicity and Laurel both rushed over. Oliver grabbed Felicity and held her close. He could see Barnes glowering from the table but ignored him. Too soon she pulled away to hug John and Roy. Barnes walked over stiffly and held out his hand.

"Mr. Queen" he said gruffly

"Sergeant Barnes." Oliver replied, he took hold of Barnes hand; and maybe squeezed a bit too hard, though Barnes didn't seem to feel it. In fact he simply smirked at Oliver and turned to greet Roy and Digg. Felicity had been watching and shot Oliver an exasperated look while Laurel rolled her eyes.

"Boys." She muttered.

"I know, right?" Felicity responded.

"Since when are you two close?" Oliver asked.

"Us girls have to stick together." A short brunette with glasses said from the couch. "There's way too much testosterone floating around here." She grinned. "Some of it is Super testosterone. Darcy Lewis, I tase Demi gods, I'm dangerous."

Oliver looked at her dazed.

"Play nice." Tony said "I just had the holes in the floor fixed, I don't need new ones."

"Sorry." Bruce mumbled.

"No worries. I actually liked the Loki sized holes, but I realized they were a health hazard after the 4th time I tripped during a midnight coffee run. Nothing gets between me and my coffee." He turned to team Arrow. "Did you bring the DNA sample?"

"Here," Digg said holding out a bag with an arrow. "And I have a copy of the digital autopsy Felicity made."

Tony's eyebrow twitched. Pepper and Bruce, now accustomed to his quirks went to Digg.

"He doesn't like to be handed things." Pepper explained to a bewildered Digg as she took the flash drive he was holding.

"He also doesn't like lower grade tech in his building." Tony grumbled as he glared at the flash drive Pepper was connecting to the holotable.

"I'll go to the lab to run some tests." Bruce said as he left.

Tony was about to open the files, when he paused to look at Laurel. "Are you sure you want to be here?" he asked gently. "No one will blame you if you want to leave."

Laurel squared her shoulders and looked at the table. "I can handle it."

Tony nodded and pulled up the 3d images of Sara's body. He began examining the image and comparing it to Felicity's notes.

"You think the arrows were thrown?" He asked

Felicity nodded. "The trajectory is off. The arrows come from close range and – "

"Have you considered the possibility of a shorter archer?" Clint asked. He tilted his head examining the data. "An inexperienced one at that?"

"The strength with which the arrows were fired – "

"Is inconsistent with that of an archer with Queen or Harper's muscle mass, but not with that of someone a lot less dense." Clint said.

"I guess Merlyn's officially exonerated." Oliver grumbled.

"Mr. Stark."

"Go ahead JARVIS." Tony shared a smug look with Clint at the alarmed reactions of team Arrow to the AI"

"Dr. Banner has run the DNA particles on the arrow and has come upon some alarming results."

"Patch him in." Tony frowned as Bruce's face appeared on one of the screens. "Define alarming results, Bruce."

"I compared the DNA to all of the SCPD arrest records from the last 4 years. The DNA was degraded, but I managed to get a match with what I had available…" he looked nervously at the corner of the screen.

"You okay Doc? You look a little green around the gills." Clint grinned as everyone at him.

"Who's the match Bruce?" Laurel stepped forward. "Please tell me who killed my sister."

He took a deep breath "According to the DNA evidence." Bruce fidgeted, "Oliver."

Everyone looked at Oliver in shock.

"That's impossible." Tony said bluntly. "The archer was significantly shorter and weaker than Queen. Forensics don't lie."

"Neither does DNA." Bruce said. "So unless there's someone smaller running around Starling shooting people who has the same genetic markers…" he caught the growing expressions of horror on team Arrow's faces.

"What?" Tony asked. "Does Queen have a mini clone that we don't know about?"

"No," Natasha said. "He has a sister."

"No." Oliver growled.

"Oliver," Felicity murmured "it's the only logical explanation."

"NO" He shouted. "I can't believe she would do this, the Thea I know."

"Thea lied to you for months about where she was." Roy said slowly.

"How can you say that?" Oliver said. "How can you even think that? This is Merlyn. He probably planted my DNA and –"

"Merlyn is also Thea Queen's father." Natasha said. She sighed at the look of shock on Oliver's face. "Secrets are in my job description Mr. Queen. Which is also how I know that until he returned to Starling a few months ago, Malcolm Merlyn was rumored to be hiding in Corto Maltese." She threw Oliver a pointed look. "I believe you're familiar with the location?"

"Thea wouldn't" he said weakly

Laurel was staring blankly at Bruce's face on the screen.

"Do you need me to come up there?" he asked her.

"No." She said shakily. "I'll come to you." She turned to Oliver. "We need to talk to Thea. We need to make sure she hasn't had contact with Malcolm."

"She told me…" Oliver began, "She's been lying to me."

"Then maybe you shouldn't be the one asking the questions." Clint suggested.

"What about Nyssa's threat?" Roy asked.

Tony snorted. "I would love to see her try to get Felicity here. Security's top notch."

"I can see a least 3 possible breaches in this room." Digg crossed his arms.

"5" Steve countered

"6" Natasha murmured

"7" Bucky growled "if we want to keep Felicity safe we need a more secure base."

"If they want Felicity, they're going to have to go through me" Laurel was standing by the elevator. "I've lost Sara and Tommy. I saw what being a part of the league did to Sara. I'll be damned if I let that happened to anyone else."

Bucky gave her a small smile. "I guess I'm grateful you'll be fighting with me this time, not against me."

She nodded and left the room.

"7?" Tony said, outraged.

"Loki just waltzed right in here and took over. Do you honestly think this place is secure?" Clint asked. "Let me tell you something about the air vents."

Lian Yu

"I thought you were going to let me starve down here." Slade faced the wall as he heard what he assumed was an ARGUS agent with his food.

"I should, but I am in need of your assistance." He turned in surprise to find Nyssa al Ghul standing on the other side of his bars.

"ARGUS, is disbanded. The head of the organization was a member of Hydra." She said.

"And now you have come to kill me for threatening your beloved Sara." He chuckled.

"Sara is dead."

Slade tilted his head. "And why should I care?"

"Because Oliver Queen allowed it to happen and has not sought the person responsible." Nyssa stood before the bars of the cell. "I offer you your freedom and your revenge in exchange for a small favor."

"And what is that?" Slade leaned against the wall of his cell. Nyssa smiled. "I need you to capture Felicity Smoak."

Slade looked at her with a look of pure mad joy. "Believe me," He murmured, "It would be my pleasure."
