Rebuilding the Bonds.

Summary: Bonds are what tie us to people, bonds of friendship, love and family. 24/Chuck crossover...Chuck/Sarah, Jack/Renee...

Set after the season 3 finale of Chuck and sometime around two years after 24 season 8, Renee starts working for CTU again assuming that she wasn't killed in 8.17, so a season/day 9 possibility.

Disclaimer: I don't own 24 or Chuck, I'm just a fan!

Chapter 1.

It's one of the worst feelings...waking up from unconsciousness. You have no idea where you are, what happened, or what day it is. The heat was the first clue. It was sweltering hot wherever they were; the room was plain with a simple single bed bolted to the floor, no fan. Of course there wouldn't be any type of comfort for the prisoner, no windows, just a thick door that was impenetrable. The most frustrating thing was that she couldn't remember how the hell she'd ended up in this position. Something had distracted her on a mission leading to her and Chuck's capture and the drugs they'd been given had successfully wiped out her memory of what had happened. All Sarah Walker knew was that she was screwed. Worst off she was even more screwed if Ellie found out, because it had take months of pining after the spy life for her to finally accept that Chuck needed this in his life. They had been following a lead to do with Chuck's mother, a connection to an arms dealer in Mexico who was once part of an elusive Fornax Group. Yes. It was official. They were screwed.

"What happened?" A voice mumbled to the right of her and she turned to see Chuck sitting up, looking around groggily. She'd been previously sat for the last hour she'd been awake with his head in her lap, carefully running her hands through his hair before she'd began pacing and worrying.

"We've been captured." Sarah muttered, still looking around for anything that could be used to escape.

"Well that's not good." Chuck muttered, sitting up and rubbing his sore head.

"No shit Sherlock." Sarah muttered slightly angrily, angry at herself for being in this situation, even angrier at herself for letting Chuck be in this situation. "Can you flash on the door? Try and break it?"

"No." Chuck shook his head helplessly, "How did we get captured?"

"I don't know, all I remember is watching the meeting and waiting for the weapon to be sighted then it all goes black." Sarah began looking around for any type of camera's. "I'm guessing Mexico by this heat."

"Why didn't I flash?" Chuck asked himself more than Sarah.

"As soon as they saw us they tranquilised us straight away I'm presuming." Sarah muttered, freezing as she heard the scraping of the lock...

... ... ... ...

A small bead of sweat ran from down his forehead and off his nose as he crouched in the cover of some bushes, watching the complex carefully. Today was a particularly scorching day, the sun was at its highest point on the medium sized complex in northern Mexico that served as the base for an organisation that bought and sold high class weapons to terrorists and other high paying bidders. He'd been there for six months, and today's temperatures were defiantly the worst he'd been in. He saw two people walking towards the building and recognised them instantly. The well built man simply gave off the presence of being in charge, his name was Raul Valdez and he ran the whole operation. He had no sense of humanity left within him anymore and cared for no one. He was possibly one of the most dangerous men in the world as he possessed a weapon that would devastate the chosen target. Jack Bauer's attention was drawn to the woman to the right of him, she was beautiful and walked with a sense of grace and danger that was almost like a mountain lion, one wrong move and you'd be dead. She was the reason he was here, in temperatures above 40 degrees Celsius, because he trusted no other agent to do everything they could to protect her. The text he had gotten scared him. It was clear, she needed to get out. She'd give him the signal and he'd move in. He felt guilty, he'd promised his family that he was done with this life. He'd promised his family that thousands of times, but when she'd gotten the job at the new CTU/LA that she couldn't turn down he'd been anxious, this assignment was the most dangerous she'd gotten so far, and he trusted no one else. After all, who would be trustworthy with Jack Bauer's heart.

... ... ... ...

Renee Walker knew as soon as she entered the room her cover would be almost certainly be blown. Why did Sarah have to show up? She was supposed to be undercover in Burbank playing happy family's while guarding someone, not be staking out a weapons hand off. Raul unlocked the door and they walked in.

"No." Sarah breathed as soon as she saw the redhead, flashes of the mission coming back, the jolt of familiarity and shock as she recognised one of the people buying the weapon, the sense of betrayal and then the sting of a dart in her neck, "What the hell is going on?" Sarah asked loudly, looking from Renee to Raul, jumping to her feet and glaring at them with betrayal and fury in her blue orbs.

"Walker, you have a minute to explain before I shoot you all in the head." Raul muttered with a bored tone in his voice and both Renee and Sarah opened their mouths.

"There's been a complication sir." Renee muttered, looking over at the blonde with annoyance in her eyes.

"What type of 'complication'?" Raul seethed.

"That's my sister." Renee admitted turning to face Raul.

"Your sister is a government agent?" He asked, processing the information quickly.

"Every family has a black sheep." Renee's eyes darkened, "I don't need to remind you of yours."

In one swift movement the gun had moved from Sarah and Chuck to Renee, pointing straight between the eyes, "Shoot her." He ordered, "Shoot her, or I'll shoot you."

"What?" Renee paled; she knew this was a possibility, a strong one, "You want me to shoot my own sister?"

"I shot my own brother." Raul shrugged, "Now hurry up, we don't have a lot of time."

"Go on Renee, shoot me if you're working for these people, you're a traitor!" Sarah yelled, "How could you do this? Betray your country!"

"Shut up!" Renee yelled back, pulling her gun out and pointing it at Sarah, "You were always so naive, believing whatever anyone told you. Grow up and look at the world around you Sarah!"

"At least I'll die with honour." Sarah shot back.

"There's no such thing as dying with honour, once you're dead your dead, there's nothing brave or poetic about that." Renee's eyes darkened, counting down in her head.

"Get on with it Walker." Raul hissed.

"My pleasure." Renee muttered turning her gun just as an explosion racked the north end of the complex, causing Raul to let his weapon drop in confusion. Renee took the opportunity to shoot him in the arm and thigh.

"What the hell is going on?" Sarah asked, watching Raul fall to the ground and Renee pick the gun up and toss it to Sarah.

"How far are your agents?" Renee asked.

"Five minutes out." Sarah told her, looking around confused.

"I need you to take him and get to the south exit, there should be a black SUV there with a man driving, tell him you're Sarah Walker, CIA and that Renee's right behind you. You'll have five minutes before this place blows up completely. You have to get Raul to the US for questioning." Renee told them, quickly unlocking the handcuffs.

"What about you?" Sarah asked, picking up the gun.

"Litar du på mig?" Renee asked, and Chuck recognised Swedish.

Sarah nodded but didn't reply as she picked up the gun Raul had used.

"Then go, get the hell out of here, I'll be right behind."

Sarah and Chuck lifted the complaining Raul up and moved as fast as they could out the room, Sarah watched as Renee started sprinting in the opposite direction, taking out a few guards as she went. Sarah and Chuck headed towards the south exit looking, moving in the shadows so the guards that weren't so preoccupied with the explosions wouldn't see them. She saw a black SUV speed up and stop before a man jumped out and disabled the two guards at the gate.

"Who are you?" He ran up to them, his gun pointing at them while curiosity filled his gaze as he looked at Sarah.

"I'm Agent Sarah Walker, I'm with the CIA. Renee said she'd be right behind us." Sarah told him, "We've got Raul."

"Put him in the boot and tie him up. Do you have backup?" He asked.

"Yeah, they should be here any minute." Sarah told him.

"There's a small clearing a mile south west of here, take Raul and the car and tell your people to meet you there. I have to get Renee." He told them.

"Let me help!" Sarah insisted, "She's my sister."

"Which is why if anything happens to you, she'll kill me." He said, "Now go."

"Please, get her out of there safely." Sarah begged the man as she started up the car.

"Get Raul to your people." Jack told them, moving away from the SUV and sprinting into the complex.

"Renee!" Jack yelled as another explosion demolished another part of the building and he had to shield his face from the heat and debris coming off the explosion.

"Jack." He saw a two figures running towards him through the smoke, the second was a child and he knew instantly why she'd gone back.

"Are you ok?" He asked, looking at the young boy who was clinging onto Renee, terrified.

"We have a minute to get out of here before it all goes up." Renee told him, moving towards the closest exit.

Jack lifted the boy onto his back and set off at a sprint Renee following him closely as they moved as quickly as they could away from the building. When the main explosion happened the force of it knocked them off their feet, throwing them forwards and causing them to land in the sand.

"You ok?" Renee asked Jack.

"I'm fine, you?" Jack asked, sitting up and getting to his feet, offering Renee a hand and then picking the boy up again.

"Yeah." She nodded, turning to the boy, "You ok Adam?" She asked, watching him nod his head slightly, fear and confusion playing on the boy's face, "Everything's ok, I promise you."

"I told the agents we'd meet them in the clearing a mile from here. What's your sister doing here?" Jack asked as they set off towards the clearing.

"I don't know, she was at the meeting last night, staking it out. It's the reason it all went south, they refused to sell and got out of there as quickly as possible." Renee muttered, "The deal was dead."

"So the weapon is still out there? Raul's people don't have it and we have no idea who the buyer was!" Jack asked, swearing loudly as Renee nodded her head.

"We need to figure out how bad this has all gone; I might be able to still salvage my cover." Renee pointed out as they set off at a quick jog towards the clearing.

As they reached it they saw two other black SUV's and a number of agents talking to Sarah and Chuck, all of whom turned to face them while Sarah rose her gun, hurt evident across her pretty face as she stared into the familiar eyes of both her sister and the eyes that had once belonged to her mother.

"What the hell is going on Renee?" She asked...

So just an idea...

What does everybody think?
Is anybody actually reading this?

I have no idea how many people watch both 24 and Chuck...
Any who, that's the first chapter, I'll update if anybody wants.
