Chapter One- Reunited

Their eyes met across the crowded bar and in that instance they both knew. She smiled slightly as he slowly edged his way closer to where she was sat, squeezing past people slumped against the bar.

"Can I buy you another drink?" he asked as he slipped into the bar stool beside her.

"That would be great thanks" she replied, feeling slightly inebriated but loving the attention from this man that she felt an instant attraction towards.

They spent the next two hours drinking and talking, the chemistry between them increased by the second and they felt like they had known each other for years. She was studying her PHD in psychology and he was currently working on a new research topic that he didn't divulge too much about but assured her would change the way people looked at detecting deception. As time passed her head grew fuzzy and her body drew closer to his. She wasn't usually this flirtatious to men she had just met but the minute her eyes found his she had known there was something special between them. He flirted back and his English accent really turned her on. He wasn't the most attractive man in the bar but he was so confident and alluring that to her he was the most attractive man on the planet.

They ended up in a cab together and when it stopped outside her apartment she asked him up for coffee. He hesitated slightly but she ran her hand along his thigh and gave him the most persuasive smile he had ever seen, which obviously he couldn't resist. Once they were inside, all thoughts of coffee were forgotten and they began undressing each other as she guided him towards her bedroom. He pushed her up against the wall and drew his hand up along the inside of her thigh pushing her skirt higher and higher before his hand reached the already damp material of her knickers. The passion between them was intense and they were so open with each other about what they wanted and what they were feeling that it truly frightened him. He was used to sleeping with women and moving on but since he had spotted her sat alone at that bar he had known that she was the one for him. This thought almost caused him to stop and run away right there and then but he had come so far and she was so intoxicating that he couldn't stop. They spent hours enjoying each other and he learnt everything that she liked and he saw her from every angle, committing everything to memory. They eventually pulled away from each other and fell back into her bed feeling drained. Within minutes she had fallen asleep with the smallest, yet cutest, smile on her face. He drew the duvet up around her and watched as her breathing evened out and she curled up into herself.

As he watched her he saw it all pan out: how she would fall in love with him, how he would so easily fall in love with her but how he would hurt her because that's what he did. He didn't trust people and he didn't let anyone close to him emotionally but he knew that she would penetrate that wall and he wouldn't stop her. She was so beautiful both inside and out and he was already starting to fall for her but he was damaged goods, he had hurt too many women in the past and she deserved better. So he did what he thought was best for her and he got up quietly, got dressed and left her apartment without leaving any sign that he was ever there except the evidence of their night of passion along her body and the memories of the passion deep in her dreams as she slept.

YEARS LATER

Cal Lightman really hated being told what to do, which didn't bode well for him when he worked at the Pentagon. He had been informed that he had to go and see a psychologist, all because of what had happened to Jimmy Doyle's family and the interest Cal had taken in trying to find out what had really happened. He knew it was the Pentagon's attempt to keep him under their control, they were hoping this psychologist would find some evidence to show Dr Lightman was mentally unstable, which they would then be able to use to discredit him if he attempted to step out of line. So he was now on his way to Dr Foster's office for his first session, as a psychology graduate himself he knew what was going to happen in these sessions and he didn't like it but he had no choice.

He approached the door labelled 'Dr Gillian Foster' and he knocked loudly three times before letting himself in. From where he was standing he could see a woman standing in front of a filing cabinet with her back to him. She was wearing a tight white shirt and a black fitted skirt, he couldn't help but let his gaze wander her figure but when she turned and he looked into her eyes he couldn't hide his surprise.

"Gill…" is all he could manage as he continued to stand in her doorway staring at her in disbelief; it had been years since he had seen her.

"Cal….I….you….wow" was all she could manage as she stared at the man stood in her doorway, a ghost from her past that she wasn't sure she was happy to see.

It had been one of the most miserable and embarrassing mornings when she had woken up expecting to find him next to her sleeping and instead found her bed empty….an emptiness that had remained in her heart. At first she had been angry that he had slept with her and ran out of her life all in the space of a few hours but as the years went by the anger had dissipated and she just felt sadness. Now faced with the man himself, she could feel the anger slowly returning. She hadn't ever really thought about what she would do if she ever met him again.

"Gill, I'm so sorry…" he began but she cut him off deciding that she had a job to do and regardless of who was standing in front of her she should maintain her professionalism and not focus on what she couldn't change.

"Dr Lightman, if you would like to take a seat" she suggested as she waved her hand towards the sofa, moving towards her chair with her clipboard.

Cal stood there speechless as he watched her take her place and realised that she was just going to ignore their history. He couldn't say he blamed her, he had just run out on her without so much as a note. He had been extremely cowardly and had agonised for years over his actions and how he had probably lost the best woman he had ever met.

She cleared her throat and he was brought back to the present where she was watching him whilst gesturing towards the sofa. He walked slowly towards her and took a seat directly across from her, invading her personal space in an effort to get close to her once again. She pulled back and arched her eyebrow at him.

"Cal, this isn't the time or the place. Now shall we get started?" she stated as such a matter of fact that Cal decided to let it be….for now at least.

Several sessions passed and they still hadn't discussed their history but they had started to get closer and he had even seen her genuinely smile at him from time to time. They discussed what had happened in depth and she tried to get him to persuade himself that this was something he should drop for the sake of himself and his family. It had taken a while but it seemed that he realised what she was trying to help him achieve and he dropped his interest in finding out what had happened that night. Instead she had got him thinking about what he really wanted to be doing and how much he hated working for the Pentagon. She heard from other colleagues, several days after their last session, that Cal Lightman had quit his job and walked out. She felt slightly disappointed that he hadn't told her himself but she assumed he had his reasons and she guessed he owed her nothing really. She was deep in thought, relaxed back in her chair, bare feet up on her desk with his book in her lap when he decided to visit her. She was startled as he burst into her office without knocking.

"Dr Lightman, you could have knocked, I might have been with a patient" she said angrily as she looked at him stood smirking in her doorway.

"Now now love….it's Cal to you…always has been" he replied cheekily before plopping down on the sofa, "good book?" His smirk seemed to deepen, if that was even possible, at the thought of her spending her spare time reading up on his life and his achievements.

She ignored the smug look on his face and tried to read him to find out what was going through his head but he was the "lie guy" so she knew it was useless.

"So I heard you quit…" she murmured as she dropped her feet to the floor and slid the book onto her desk.

"Doesn't take long for something to get around this place does it?" he joked shifting towards her, tilting his head to the side as he studied her face.

"Why are you deflecting?" she asked her brow creasing with confusion.

He chuckled, "yes love, I quit but I really had wanted you to find out from me" he replied genuinely sorry that she had found out through the grapevine.

She looked at him and let his words wash over her, "you could have come straight here to update me when you told them, ever so politely I'm sure, where to shove their job" she said a small smirk playing on her lips.

"That is very true but to be honest I needed to clear my head before I came to you" he explained spreading his hands across his knees, his eyes focusing on the action rather than on her.

"Why?" she asked, genuinely interested in why he had needed that space before he came to her.

"Come to dinner with me and I'll explain everything?" he asked, she could hear the hope tingeing his words.

"When?" she questioned, biting her lip at the thought of spending time alone with him outside of a professional setting. Although she was still angry at how he had treated her years ago, she had never forgotten the spark between them and spending time with him in their sessions had only reminded her how much of a spark there really was.

"Tonight….if you're free?" he asked smiling nervously as if he really thought she might say no.

"Ok" she replied not knowing what else to say and surprisingly shocked at how nervous he appeared to be.

"Great, I'll see you at 8, you know Carlo's?" he asked as he stood up and straightened out his jacket.

"Of course, I'll see you there" she replied smiling at him as he made his way over to the door.

He reached for the door handle but turned towards her just before he opened it, "Oh and Gill….I really am sorry" he said to her before disappearing through the door. She sat staring at the door for a long time after he had left, not really sure she understood what had just happened or what he was really apologising for.
