The Qwib Qwib entered the Sol system after abit of a delay, Cerberus forces had been abit more heavy handed with the ship then Tali had intended, but Quarian ships were known for thier bad condition, everyone would just see the left over damage as a typical patch up job. The Cerberus forces had disguised themselfs with the suits of the dead Quarians, thier owners had been disposed of out the airlock. Tali had changed into Zaals suit which luckily was able to hide her figure. She had to replace his visor with a new one after she had shot Zaal through it. With some modifications to the mask, she had added a voice distorter that was concealed over her mouth, to cover up her voice and sound more like Zaal.

"Testing, testing.." She said to herself, her voice came out deeper and more manly. She felt sick, "Oh not again" She thought angrily, for the past couple weeks she'd been waking up with high fevers, cramps and the urge to be sick. She had put it down to working in Cerberus bases and aboard thier ships, they wern't very Quarian friendly. Yet it still got her most irritable.

"Ma'am.. I mean Sir.. Err Ma'am" One of the Cerberus officers said.

"What is it!" Tali snapped at him

"Operative has given the go." He replied.

"Alright all hands to your stations, take her in easy." Tali said addressing the bridge crew.

The Qwib Qwib headed towards Earth. Operative had gone ahead in an Alliance shuttle with a small group of infiltrators, she was to make a round trip and then approach the Qwib Qwib in the pretence to meet the Qwib Qwib and escort her down to Admiralty Headquarters. As they neared closer, the Citadel loomed ahead to thier left as it shared Earths orbit with the Moon. The Citadel had been on the brink of destruction after the battle for Earth, it had been deemed to be structurally unstable and that any attempt to move the Citadel could result in the structural integrity collapsing. "Good" Tali thought, she watched as groups of frigates and cruisers patrolled around the system.

As the Qwib Qwib reached closer to Earth, an Alliance shuttle approached. "Right on time Operative." Tali headed down to the small docking area where the shuttle was now waiting. She made a detour on the way and popped into engineering, she typed a few commands into the main engineering console then fitted a transmitter hidden under it. She walked into the docking bay and boarded the shuttle where Operative was waiting in a Alliance uniform along with two disguised Cerberus infiltrators.

"It suit's you Operative" Tali sneered.

"Shut it!" Operative growled back at her. She wasn't used to people joking with her or mocking her, those that did, died shortly after. But Tali was The Illusive Mans new prized pet, for now she was untouchable.. but she could wait, one day her usefulness will be at a end. "And i'll have a clip with your name on it" She thought as she stroked her pistol.

The shuttle undocked from the ship and headed down into Earths atmosphere towards Alliance HQ. Tali double checked she had everything she needed, she hid her knife in a hidden pocket on one of her boots. There was no way she'd be able to smuggle a gun into Hacketts office so she'd need to either her hands or that knife to kill him.

"Ok quick review" Tali said. "When we land, you three will escort me to Admiral Hacketts office, you will then head down to the next floor and relieve the security detail. You will then loop the security feeds to the Admirals room." She paused as she felt sick again. "You will then signal me and I'll proceed to kill Hackett and hack the data we need. When I got that I'll head down to the shuttle bay where you will be waiting ready to collect me."

Operative gritted her teeth but didn't say anything, just nodded.

. . . . .

Shepard paced around Hacketts room, he'd been back for a few days now and had been on leave after the incident on Haestrom. But Hackett had called him up at the last minute to help discuss the situation with Tali to Zaal'Koris.

"How do you think he'll react?" Hackett asked.

Shepard sighed. "I'm not sure, not spoke with him since the war ended with the Geth.. I doubt he'll be happy that it took this long for the Quarians to find out."

"We'll have to show him that video feed you recovered, I doubt he'll believe she could be indoctrinated otherwise. What with thier weak immune systems, I wouldnt of thought a Quarian could survive the process."

"Talis strong.." He replied sadly.

"I cant say I know how you feel, but atleast you can take comfort in that her actions arn't her own."

A knock came at the door. "Come in." Hackett said.

The door opened and Zaal'Koris stepped into the office, he had been escorted by three Alliance personnel. He greeted Hackett when the door closed behind him, then froze when he saw Shepard.

"Whats he doing here!" Tali thought to herself taken completely by surprise. "Admiral, thank you for seeing me.. and Commander Shepard, I didnt expect to see you here." She said trying to regain her focus.

"Admiral Hackett invited me to intend, given that Tali is a close personal friend and a memeber of my crew." Shepard replied, Tali nodded at his reply.

"As your aware." Hackett started to say, "Tali went missing nearly a month ago now, she was kidnapped by Cerberus forces when they stole the Normandy."

Tali stopped listening as Hackett kept on talking, she scanned the room and saw the terminal she'd need to hack to get the data they needed. She started to pace the room, moving closer to them and the terminal.

"We found evidence while on Haestrom." Shepard started to add.

"What was you doing on Haestrom Commander?" Tali said interrupting him, she needed to buy time untill Operative sent the all clear. She also needed to figure out how she was going to get past both of them and get the data.

"As I had said Admiral, we were contacted by the Geth who picked up the Normandy entering the system." Hackett replied.

"And what evidence did you find?" Tali asked.

"We found a video recording.. of what Cerberus had been doing to Tali since they had kidnapped her, it showed them forcing indoctrination on her." Shepard managed to say.

"What?" Tali said, she was honestly taken aback. "Thats ridiculous." She thought to herself. "Don't be absurd, Quarians cant be indoctrinated. Our bodies wouldnt survive." Which was true she thought to herself, so no way could she be.

A voice that only she heard, came over her hidden comms device. "Your all clear." Operative said.

"We guessed you would think as much, and we don't blame you." Hackett said, "So if you follow us outside, we can get you a copy of that data."

"Shit." Tali thought, she had to think fast.

As the three of them headed towards the door, Tali knelt down to seeminly adjust her boot, Shepard and Hackett had both taken steps ahead of her. She pulled out the knife she had concealed and stood up fast, she moved quickly behind Hackett, swung her arm around his neck and brought the knife across his throat in one clean fast slash.

She turned her attention to Shepard as Hacketts body collapsed, the attack had completely caught him off guard, he reached his waist for his pistol and tried to take aim but he was too slow. Tali had moved in close and brought her knee right up into Shepards stomach, winding him and causing him to fall back. Tali picked up his pistol as he coughed on the floor, taking aim at his head.

" Zaal'Koris! Why!" Shepard coughed out.

Tali raised her hand to her mask, she clicked around the mouth and removed the distorter. "Keelah se'lai my love."

Shepard froze in shock, "Tali?"

"The one... and only.." She replied in her old seductive tone.

"Tali please! listen to me, this is not you... you're indoctrinated!" Shepard shouted.

"Oh please... don't give me that bullshit, just because I now serve a higher cause!"

"Cerberus? Harbinger? They are not higher causes!"

"You can't see the bigger picture can you? Everything we are doing, everything we will do.. We will bring this Galaxy to order! Our victory we mark a brilliant new beginning for every living thing!" She shouted back at him, then her tone changed and spoke in a more seductive way. "Join us.. Join me... we could bring in a new age together! Side by side."

Shepard couldn't believe what he was hearing, he couldn't believe just how deep had she sunk.. "Tali, thats crazy.. listen to yourself!"

Tali felt rejected. "No! You listen! If you get in my way again... I will kill you.." And with that, Tali smashed the pistol around the side of Shepards head, knocking him out cold. She looked down at him, she knelt down and stroked his face softly before getting up and heading over to the terminal. She began hacking, when she found the data they were looking for downloaded it to her omni-tool. When the download finished an alarm sounded, she had triggered a hidden security routine, "Bosh'tet!".

The door opened, before she could give anyone the chance to say or so anything, she turned on the spot and fired. Two guards dropped and she ran out the office, she could hear Alliance moving in on her, the only way she could go was up.

. . . . .

Operative was furious, with the alarms going it was going to be near impossiable to escape with the data. She tuned the Shuttles comms device to pick up news on what was going on, they had found out that the Quarian had killed the Admiral and was escaping on foot. "Fucking bitch!" Operative said to herslef as the shuttle took off and escaped.

. . . . .

Joker entered Hacketts office with Alliance forces and saw both Hackett dead and Shepard laying on the floor.

"Commander!" Joker shouted as he moved to help him up.

"Ugh" Shepard was all he managed to get out as he came round, he rubbed the side of his head which was in agony. "Wheres Tali?"

"Tali? Shes here?" Joker said

"She was disguised as Zaal'Koris.."

"Well they got someone cornered on the roof, it must be her".

"We need to get up there and stop her" Shepard said struggling.

. . . . .

Tali stood near the edge of the roof, she had ditched the pistol when it ran out of clips and now Alliance forces had her cornered. She had tried to contact Operative but got no reply, "Most likely she escaped while she could of.. I know I would of if I was her" Tali thought. She looked down, it was a long drop. More Alliance had came up onto the roof and with them was Shepard and Joker.

"Its over Tali." Shepard said, "You got nowhere to run now, just give it up."

She watched Shepard and was about to reply when a shot interrupted her. A sharp pain erupted in her shoulder, her hand moved to the wound and she looked down to see the blood on her fingers. She looked back up at who hard fired the shot.

It was Joker. "That one's for EDI." He said coldly.

She staggered back slowly, taking one last long look at Shepard before falling off the edge.
