A wide grin spread across Colonel Jack O'Neill's face as he walked into the infirmary. "Doc," he greeted as he saw the petite doctor.

At the sound of that all too familiar voice Doctor Janet Fraiser turned. "Colonel Jack O'Neill," she said with a smile.

They stared at each other for a moment before both moved at the same time and Janet was practically swallowed up in Jack's embrace.

The remaining members of SG-1 glanced at each other before turning back to the pair, Daniel clearing his throat loudly.

Jack rolled his eyes and reluctantly released his hold on the woman before he turned back to face his team. "And leave it to Daniel to know exactly when to interrupt...this is Doctor Janet Fraiser, the SGC's new CMO," he said to his team. "Doc, this is the rest of SG-1. Captain Sam Carter, Doctor Daniel Jackson and Teal'c. That's with an apostrophe 'c'," he said leaning over to her.

Janet smiled at them and greetings were exchanged.

"So," Daniel said, his arms folded across his chest. "You two know each other?"

Again Jack rolled his eyes at Captain Obvious. "Yeah, the Doc was...well, my Doc way back when..."

Sam's eyes lit up always eager to hear about Jack's past life in the military. "You mean when you were in Black-Ops?"

Jack frowned slightly thinking of all the incriminating things Janet could spill to his new team.

Janet laughed at the look on the Colonel's face knowing exactly what was going through his mind. "Don't worry Colonel," she assured him. "It's all still classified."

His expression cleared and he smiled at her. "Of course it is," he agreed. Then he turned to Daniel and Carter pointing a finger at them. "Hear that? Classified! So don't go bothering the good Doc here trying to dig up dirt!"

Daniel and Sam glanced at each other knowing their plans had just been busted.

Jack sat on the bed in the exam room and watched Janet prepare his shot.

"It's good to see you," he said.

She turned with the syringe in her hand. "Still not going to get you out of this shot."

"You always could see right through me," he said with a sigh.

Janet smiled as she quickly got the vaccination over with. "It's good to see you too," she replied finally. She turned back to drop her gloves in the bin and couldn't help but think how good it was to see him. He looked good. A little greyer, a little wiser maybe. Age suited him.

"You know I heard you'd retired after..." she looked at the ground, then back to him. "I'm so sorry Jack," she said reaching out a hand to cover his where it rested on his leg.

He smiled ruefully. "Thanks."

"So, how's Sara?" she asked trying to brighten the mood.

Jack lifted his shoulders in a shrug. "We're divorced. When I came back after my first mission through the gate, she was gone."

Janet sighed. "Sorry to hear that."

"Yeah, well...so was I..."

They were silent for a moment before Jack shook himself out of his funk. "So, what about you?" he asked. "How's what's his name?"

Janet smiled remembering how Jack would never say her husbands name or he'd always purposely get it wrong. "He is history!"

"Yeah?" he asked not even trying to look sorry about it. "Good." At Janet's raised eyebrows he continued. "The guy was a jerk who was never good enough for you Janet. And the offer to beat the crap out of him still stands," he added.

She rested one hand on her hip. "The answer was no back then Jack O'Neill, and the answer is still no now."

He shrugged. "Well if you ever change your mind, just say the word."

She chuckled as she placed a hand against his cheek. "What am I going to do with you?"

He placed his hand over hers and grinned. "Haven't we had this conversation before?"

"Yes," she agreed with a smile as she fondly remembered the almost inappropriate amount of flirting they used to do. "You were a terrible flirt...I had to keep reminding myself that your were married!" Were married, she thought briefly.

"So were you," he said softly his eyes on hers.

Janet took a breath, her heart trip hammering in her chest at the look he was giving her. And now neither of them were married. She smiled as she pulled her hand away from him taking a step back. "Well I can see the flirting skills are still as sharp as ever," she said lightly.

Jack cleared his throat as he stood from the exam bed. "A little rusty to be honest," he replied. They stood a little awkwardly for a moment before he reached out a hand to her face. "It really is good to see you Jan."

It took all she had not to turn into his touch. She smiled brightly. "You too Jack."

He nodded and dropped his hand. "I'll see you later then."

She smiled and nodded as she watched him walk out the door.

The next few days passed in a bit of a blur for Janet. Her new job was equally as exhausting as it was exhilarating. Looking after all the SG teams was one thing, running the regime of tests that were required every time they came back from being off world was challenging to say the least and it seemed that every day she added to the barrage when some new threat was encountered. All in all it had been one hell of a first week. And all in all she thought she'd done pretty well, with only one little thing she'd encountered this morning nagging at her. She rubbed tired eyes and looked down as her stomach growled loudly.

"Looks like I'm just in time," Jack said as he entered her office without knocking.

Janet looked up and smiled at him. "Hi Jack."

That was another thing that had made it one hell of a week, seeing Jack O'Neill again. They'd fallen back into their old flirting habits pretty much immediately and Jack had managed to drop in to see her everyday since. A slight blush crept up her throat thinking about their little exchange in the deserted commissary last night, the innuendo going way past anything they'd ever done before.

"You coming for some lunch?" he asked.

Janet screwed up her nose. "I suppose," she sighed.

Jack chuckled at her response. "Don't sound so enthusiastic! A guy could start to think you didn't want to eat with him."

She laughed. "Believe me it's not you," she assured him. "I've had nothing but mess food for breakfast, lunch and dinner for the past week...and its wearing a little thin."

He regarded her for a moment before he spoke again. "Well I might be able to do something about that..."

"Really?" she asked hopefully.

"Well not right this instant," he replied. "But if you think you can make it through another plastic wrapped sandwich today, I could have something really special waiting for you if you come over to my place tonight," he said with a cheeky little grin.

Janet tried to push down the images that had conjured. He's inviting you to eat dinner Jan, not him...and somehow that thought didn't help at all! She felt that blush begin to creep over her cheeks as she cleared her throat. "Are you offering to cook me dinner Colonel?" she asked finally.

"Yeah sure you betcha," he replied with a grin.

As if getting tired of waiting for her to reply, her stomach gave another loud grumble.

Jack grinned. "Guess that's settled then."

Janet choked down a pre-prepared chicken salad sandwich while she watched Jack gorge himself on a piece of pie and three pieces of cake.

"You know you should eat more than desert," she admonished.

"This covers all the food groups," he argued, continuing at her disbelieving look. "Fruit and breads and cereals are covered by the apple pie," he said holding up two fingers. "Dairy, meat and eggs and oils are covered by the cake."

Janet rolled her eyes as she stood and gathered their trash. "That's a pretty loose translation."

Jack shrugged as he held the flap of the bin open for her. "I ate healthy for breakfast," he said as they walked out into the corridor heading for the elevator.

When they reached her floor, Jack held the elevator door as she got off. "So I'll see you tonight then," he said softly.

Janet felt her tummy do a little flip at his mention of dinner tonight and suddenly she was feeling more than a little nervous.
