Tony and Sarah have been dating for two years now, but Tony went on a mission, with Sarah's mother; Ziva David. They were undercover as a married couple. Sarah stayed with a friend of hers, who works for the FBI, she was sitting in their offices, when the FBI were watching Ziva and Tony. Sarah saw what happened. They slept together. She didn't know about the mission, and no-one at NCIS knew about Sarah and Tony being together, her friends at the FBI did. Sarah refused to talk to Tony after that, and when Tony managed to get Sarah alone in the bullpen....

"Sarah, why won't you talk to me?" He asked grabbing her shoulder to stop her walking away, "What have I done?"

She sighed, and shrugged off his touch, "Don't touch me!"

His face dropped, "Please Sarah, tell me what I've done"

They hadn't realised Abby was watching from the stairs as Sarah turned to him, anger writen across her face, "What you did! What you did was sleep with my mother! When we were meant to be together! What the bloody hell do you think you were playing at?"

He looked at her stunned and shocked, he had no idea she knew about it, and this was clear on his face, "Err well ermm"

She shook her head, "Didn't think I knew that did you?"

He shook his head, "How did you find out?"

Sarah wiped a tear from her cheek, "I was at FBI headquarters, they had it up on a big screen in their bullpen, they watched the whole thing, how do you think that made me feel Tony?"

Abby couldn't stand it anymore and moved forward and hugged Sarah tightly, and threw daggers with her eyes at Tony, "How could you Tony?"

He ran his hand through his hair and sighed, "Sarah, it didn't mean anything"

Gibbs, Ziva and McGee came in, and Gibbs asked, "What didn't mean anything Tony?"

Sarah was in Abby's arms, being comforted by the young Goth, Abby looked up at Gibbs, "Its not good Gibbs, Tony cheated on her"

Gibbs looked angry, "You did what? You dated me daughter! Since when? And who the hell did you cheat with?"

Tony put his hands up in defeat, "I swear I didn't, she's got the wrong idea"

Gibbs glared at him, and Abby answered, "He cheated on her with..." she was cut off by Sarah covering her mouth, making everyone look at her, as her eyes were wide, looking at Abby

"Don't tell them, I don't wwant her to get the blame, she had no idea that we were dating", Sarah said before uncovering Abby's mouth, and hugging her again

Ziva moved forward, "Who had no idea?"

Abby rolled her eyes, "You"

They looked shocked and Tony sighed, "See, I told you, she's got the wrong idea"

Sarah turned, furious, leaning slightly to Tony, "I know when things like that are fake Tony, I hang around way too many NCIS agents, FBI agents ands CSI's to know that not one bit of that was fake, and believe me not one FBI agent that was there whilst that bloody video link was on, said that it was faked! So don't you dare bullshit me with that crap DiNozzo!"

Tony sighed , "Fine! It wasn't faked, but I swear it meant nothing, it was the missiopn nothing else"

Sarah rolled her eyes, "And how am I meant to believe you?!"

Gibbs looked furious, McGee had stood back, Abby was ready to get Sarah out and Ziva was gobsmacked.

Tony gave up talking realising he would never win, and instead kissed her, she couldn't resist and her arms linked around his neck, as his arms went to her waist, adn when air was necessary they pulled apart.

She raised an eyebrow at him, "Don't you dare think that you got away with it that easily, you have a hell of a lot to prove"

Tony nodded, and pressed a gentle kiss to her head, "I know" he said as he pulled her into his arms tightly, with the team looking on with shock
