"Sarah, what are you doing here?" Jack asked, keeping the plate of food in his hands.

She smiled. "Came to see you of course, what else would I be doing here?"

Jack hated to think what else she would be here for, he didn't like that she was here in the first place. "Why?" He asked increduloudly.

"What sort of question is that?" She asked him, wondering why he wasn't being the slightest bit friendly to her. They had, after all, been married for a time.

"One that could do with an answer." Jack stated simply. "Why are you really here."

"You've been stranded on an island for years, Jack" She said, as if that provided an answer for him.

He shook his head, looking down at the food. "You didn't need to come."

"I wanted to." She told him. "When I saw the rescue operation on the news and that you were still alive, I had to come out here, and when I spoke to your mother, she let it slip what hotel you were staying in, so I came as well."

Jack looked over at Margo, who was sitting alone now that Kaia was dancing with Sawyer, and then back to Sarah. "Does she know you've come?"

Sarah shook her head. "No."

"Still sneaking around then, I see." He digged. He was in no mood for Sarah, and surprisingly, he hadn't been for a long time. They might have been married, but that didn't mean anything anymore. She had been behind his back before, and with another man.

"Jack, this is hardly the time-"

"You haven't spoken to me for thirteen years, Sarah. I've only been gone for ten." Jack told her venemously, turning to put more food on the plate.

"Things were complicated." Sarah reminded him. "You had you're work, I had-"

"Someone else on the side." Jack finished for her.

"Jack! Please!" She said rather loudly.

"Please, what?" He asked her, without looking at her.

"Just hear me out, for Christ's sake!" She begged him.

"For what?" He asked her.

"Let me explain."

Jack stood there for a moment, then answered her. "Can we do this quickly, I've got people to get back to."

"I'm sorry, Jack." She told him quietly. "I'm sorry that I hurt you. It was a rough time for both of us. You had problems with your father-"

"Don't talk to me about my father!" He said in a low dangerous voice that would have stuck fear into the heart of even a maternal polar bear protecting her cubs. He looked at her as he said this, but then went back to the food.

"-And you were working all the time." She continued, as if she had never even heard him. "You were never home, Jack. I was your wife, and sometimes I went for days without seeing you."

"Like you said, things were complicated." He pointed out, still piling food on the plate for the children. He was getting a variety of everything so that they could try new things.

"Why are you doing this, Jack?" She asked him unfairly.

"Doing what?" He asked her.

"This! Why are you so hostile?"

"I'm not hostile." He lied. He was very hostile, mainly because he'd like nothing better than to never see her again at that moment. He was missing Kate too much to stand and talk to his ex-wife.

"I apologize to you, and you're tearing me to pieces." She accused him.

"Sarah, this is really not a good time." He said, hoping this would explain things to her enough for him to leave him alone. Of course, he should have known better with Sarah.

"It never is with you." She remembered.

"Sarah-"

"Please, Jack, let's give it another try."

Jack was so stunned that he acutally forgot where he was, let alone what he was going to say previously. Give it another try? Another try? Surely he hadn't heard her right.

"Excuse me?"

"We had something special, Jack, if only for a while. Who's to say we can't have it again?"

He was to say, that's who, him and Kate, and their wonderful children.

"You can't be serious." He said with a nervous laugh.

"Do I look like I'm joking?"

No, she never was. Nothing was ever a joke with her. "Sarah, I can't." He said strongly. "I won't."

"What?" She asked, taken aback.

"I won't be with you again." He said simply with a shrug, putting the finishing touches to his plate of food.

"Why not?" She asked him, clearly horrified. "Things could be perfect. If you cut down your hours at work, and we can get a new place together...we could start that family that we wanted..."

Just as Jack was about to reveal his new meaning of family, Kaia came to his rescue.

"Dad!"

He heard her voice, and looked around for the location of it. He finally saw her standing on the dancefloor, where she was now running over to him from. Sarah followed Jack's gaze, and saw Kaia. She watched in a mixture of confusion, horror, and hatred as Kaia came over to Jack excitedly, with that big grin on her face, and stood at his side laughing to herself, hugging his legs. Sarah and Kaia locked eyes for a moment, both wearing a strange expression; Kaia's almost nervous, afraid of her. This look disappeared when Jack noticed and ran his hand over her hair softly.

"What's the matter, baby?" He asked her gently.

She shook herself back into her party-mode. "I want to dance." She stated, looking up at Jack expectantly.

"Yeah, I saw you dancing with Sawyer, you having fun?" He asked her, finding that he didn't need to force a smile for her sake because she always brought a smile to his lips.

"Yeah, but I don't want to dance with Sawyer anymore." She said with a shrug. "Sawyer wants to dance with Ana Lucia."

That didn't surprise Jack at all. "No? Then who do you awnt to dance with. What about Aaron?" He asked.

"NO!" Kaia said, shocked at this suggestion. "I can't dance with Aaron!"

"Why not?" Jack asked laughing.

"Cause Aarons a boy! He doesn't know how to dance properly!" She explained, as if it were simple. "Cause I wanna dance with you."

"In a minute, honey." He promised her.

"DDDaaaaaaddddddddddyyyy..." She begged, using the puppy-dog eyes that he wished Kate had never taught her. Then her eyes fell on Sarah again. "Who's that lady?"

"Her name's Sarah." Jack explained.

"Hi." Sarah said simply, forcing a smile.

Kaia looked at Sarah, and then up at Jack. "I don't like her." She stated.

"Kaia!" Jack jumped in quickly. "Be polite!" He reminded.

Kaia stayed at Jack's side, standing behind his legs slightly, his hand was still on her head, and from a distance, it was clear to see the protection he was emitting against Sarah, although he didn't know why he felt he needed to keep Kaia away from Sarah.

"You have a child?" She asked strangely.

"Children." He corrected. "I have children."

"Your plane crashes, and you have children with another woman?" She asked, running the scenario through in her mind and deciding that it was ridiculous.

"A woman who I love very much." Jack added in.

Sarah went quiet, and then her voice dropped to almost a whisper. "You loved me once." She reminded him.

"You broke my heart, Sarah. That's not love." He told her.

Sarah looked around. "Where is she then?" She asked expectantly. "Where's their mother? Where's the love of your life?"

In any other scenario, this would be when Kate walked out and presented herself, and more than likely, shown Sarah who was boss. But she didn't. She couldn't.

"She's not here, and that's no business of yours." Jack said before she could ask any questions.

Then Curtis called over, taking his turn to save the day for Jack. "Daddy! Where's my meat? I've run out!"

"Just coming." He told him.

Sarah just nodded. "Keep in touch, Jack. Goodbye." She told him, and then turned on her heel and disappeared into the crowd. Jack watched her go, and then tried to steer Kaia back in the direction of the table. Instead, she didn't move, watching after Sarah as Jack had done.

"Come on, Kaia." He said quietly.

"Daddy, that's her." Kaia said desperately, tugging on his trouser leg, begging his attention.

"Who?"

"That lady. It's her." Kaia repeated.

"What about her?" Jack asked, stopping and bending down to her level. Something about the scared look in Kaia's eyes worried him.

"She's going to do something horrible to us." Kaia told him.

Jack frowned, but then smiled at Kaia. "No, she's not, baby."

"No," Kaia protested. "I saw her do something nasty when I was asleep."

Jack remembered his dream suddenly. The dream he had on the boat, of Kaia warning him, Kate begging him, Curtis screaming. Jack shook it out of him. "Come on," He said, taking Kaia's hand. "Let's give Curt his meat."

"Then can we dance?" She asked him hopefully.

"Then we can dance." He smiled at her.
