It was just another day on the island. Like any other, there was the threat of the others, food was scarce and everyone was beginning to loose hope they'd ever be rescued. One of the survivors however was over the moon. Little over a month ago Kate had been captured by the others and lost Jack and Locke there one chance of confronting them. Jack had been quite angry with Kate for several days, still confused about the kiss they'd shared previously. It hadn't taken long for them to make up and make their relationship official.

Kate was leaning on a tree watching Jack tend to everyone the way he always did. He handed water to Rose and Bernard and then went to check that Aaron was all right. Kate smiled as she saw Claire and Charlie look up as Jack talked to them. It was his caring nature that she'd first fallen in love with.

"Hey," Kate said as Sun came over.

"You're staring at him again," she commented smiling and handing Kate a bottle of water.

"Sometimes it's hard not too," Kate replied taking a drink from the plastic bottle.

"Are you coming to the garden or…?" Sun trailed off glancing meaningfully at Jack.

"You don't mind do you?" Kate asked, worried her friend may be mad at her for abandoning their project.

"Of course not," Sun said taking back the water bottle Kate was holding out. "See you later."

"Bye," As Sun wandered off Kate saw Jack heading towards her.

"Hi," Jack said walking up to her.

"Hi," Kate smiled, turning slightly pink.

"You ok?" He asked, glancing back at Claire and Charlie who were tending to Aaron.

"Yeah, you?" Kate asked awkwardly, still not entirely used to the idea that she didn't have to hide her feelings.

"Yeah, Charlie and Claire are playing happy families now that they know Aaron's rash is nothing to worry about." Jack grinned. "The way they are together you'd swear they were a married couple."

Kate laughed.

"I'm surprised they haven't announced their marriage." She said watching the pair together.

Kate and Jack stood in silence for a moment, unsure of what to say.

"So, umm, did you… did you want to… come for a walk?" Asked Jack suddenly, stammering over his words.

"Sure," Kate said, linking he fingers through Jack's. He was a little taken aback by the gesture but didn't show it.

They wandered through the cool trees, enjoying each other's company.

"How's Sawyer?" Jack scuffed his feet through the leaf litter. "I haven't spoken to him much since his shoulder healed."

"He's ok," Kate replied. "He's worried about Michael. Both him and Jin are."

Jack nodded.

"Michael will come back." He said, though a part of him wondered whether Michael would return.

"How's Ana?" Kate didn't meet Jack's gaze as she said this, thought the jealousy was obvious in her voice.

"Oh you know," Jack said smiling to himself. "She gives me certain signals from time to time, but she knows there's only one girl for me."

Kate blushed, but smiled.

"Really?" She asked, her tongue between her teeth.

"Yeah," Jack led them deeper into the jungle. "She's sweet and kind and has a good sense of humour."

"Oh yeah? Do tell," Kate said innocently.

"She's quite cheeky too," Jack said, ducking as Kate took a swing at him.

"Don't get cocky, you," she said suddenly stopping. Jack paused and looked at her.

"Are you ok?" He asked, concerned.

"Yeah, jut went dizzy," she said, breathing carefully as a wave of nausea swept over her. She hadn't mentioned to Jack that this was the fourth day in a row she'd felt sick. She thought it was just the heat and didn't want to worry him.

"Come sit down for a minute," He said leading her over to a tree stump. She sat down, trying not to think about how sick she suddenly felt. "Here, have a drink."

She took the bottle of water and drank from it.

I'm gonna be sick," she muttered, putting a hand over her mouth instinctively. Jack removed her hand and helped her lean over so she didn't get covered. When she'd finished and was breathing properly he sat her back up.

"That was awfully sudden for a virus," he commented. "Did you feel sick earlier?"

"Not really," Kate replied, her eyes watering. "I woke with a headache but that was just because I was dehydrated."

"Have you been sick at all over the past few days?" Jack asked frowning.

Kate bit her lip, wondering whether to tell him. It couldn't be anything serious could it?

"Yeah, I've been sick the past few mornings," she admitted. Jack frowned but didn't say anything.

"C'mon, we'd better get you to the caves where you can rest," He said helping her stand.

"It's not anything serious is it?" Kate asked worriedly.

"I shouldn't have thought so," Jack replied, not meeting Kate's gaze. He had a horrible sinking feeling in his stomach. Could the night they spent together last month have had more consequences than they first thought?

He led her back to the caves and sat her on one of the beds in the make shift infirmary.

"When does the sickness come on?" Jack asked, shuffling through some notes he'd been making about each of the survivors.

"Usually mid morning," Kate replied, frowning.

"How long has it been going on?" Jack scanned his notes, his frown deepening.

"I dunno," Kate thought. "About a week? Maybe less."

Jacks sighed, wondering how exactly he was going to tell Kate his suspicions.

"What?" Kate noticed the sigh. She stood up and walked over to him. "What's wrong with me Jack?"

"Kate, I can't be sure unless I can run a proper test," Jack began. "Which on the island is impossible."

"Jack, you're avoiding the question." Kate said looking at him worriedly. "What's wrong with me?"

"You're pregnant," Jack said quietly not meeting her gaze.
