Kate was back. She was no longer a child, she was back to the woman that she had been before, in all her glory. Jack looked over at Sun, who was grinning just as much as she looked at Kate. "When-when did it happen?" He asked her, not sure of how to word it. After all, he wasn't sure what had happened, except that Kate, his Kate, had come back.

Sun shrugged her shoulders lightly. "I don't know. I just came in a few minutes ago and saw her."

Jack no longer cared why or how it had happened, all that mattered was that she was back. He gently moved from beneath her, remembering that she had been ill, and knelt beside her, leaning over her as he put a hand on her forehead. "The fever's gone." He announced, going about checking things. "Breathing's good...pulse is fine...just got to check that bite." Carefully, as not to disturb her sleep, he sat her up, and leaned her against him so that he could check over her shoulder. "That's weird." Jack said to himself. "There's nothing there." He told Sun. "Not even the puncture wounds."

"Jack..."

Hearing Kate's gentle, tired moan, he stopped where his fingers were running softly over the skin of her shoulder. "Yeah, Kate?" He said breathlessly, amazed that he could hear her voice like he used to again.

"Mmm...Your hands are cold." She mumbled, moving her head so that she was more comfortable with her cheek pressed against his shoulder, and he felt her breathing against the side of his neck. He removed his 'cold' hands, and rubbed her back gently through her t-shirt. "Thats better." She said, almost drifting back into sleep, but something stopped her.

Her eyes snapped open. Her breath caught in her throat. Her heart ran overboard inside her chest, thumping wildly. She lifted her head from Jack's shoulder, now fully awake, and stared at him. He reached out, putting a hand on the side of her face, making sure that this was real, that she wasn't an illusion, and she found herself doing the same thing. She laughed, happy tears springing to her eyes as every action she took was mirrored in Jack, only his tears actually slipped down his cheeks.

"Is it over now?" She asked him.

He nodded, biting his lip subconsciously. "Yeah," He replied throatily. "Yeah, it's all over. You're back."

She threw her arms around his neck, acting so quickly that she caught Jack off guard and he had to put a hand behind him to steady himself before wrapping both arms tightly around her, both of them letting silent tears fall down their cheeks as they laughed with each other. Jack pressed her firmly against him, like he had wanted to do for the past week, kissing her cheek, the only part of her face that wasn't buried against him, with every available chance. He never thought that he could miss her as he had done because of the change.

"KATE!"

Voice broke the couple apart, and they both looked over Jack's shoulder to see Claire and Shannon. Both of the other women came over and hugged Kate on their knees as well, either side of the pair. All three of the women were laughing together. Other survivors were gathering near the edge of the cave, peering in at Claire's call to see the regular Kate back again. Even though he was going to be losing a playmate, Sawyer, too, looked curious, and glad to see her back again.

Kate smiled at the people around her, everything she had been through the last few days was finally over. Flinging herself at Jack again, she kissed him, regardless of everyone watching.

Twenty minutes later, the crowds had diminished, and they had ventured out for breakfast. As usual, they went to where Claire was feeding Aaron, along with Charlie, Shannon and Sayid. Sitting down beside Jack, rather that the urge she had to crawl up in his lap (guessing she wasn't completely over her change), Kate took the food that was passed to her, and started eating. She stayed as close to Jack as she could get without sitting in his lap, with their shoulders brushed up against each other, and she was subtly leaning against him.

"At last, no more troublesome four year old Kate." Charlie sighed happily. "There is a God."

Kate threw a small stone at him which bounced off the top of his head. "I wasn't that bad." She said.

"So you remember it then?" Jack asked.

Kate nodded. "I could see it all happening, I just couldn't control myself." She told them.

"When people say 'Get in touch with your inner child' they don't mean it literally." Sayid joked.

"Like I had a choice." Kate mumbled, causing Jack to laugh, and wrap an arm around her shoulder.

"I don't care what happened as long as you're back." He told her quietly, so that no one else could hear what he was saying.

A voice came from behind them, and they saw Sawyer slinking along with some food and walking past them. He didn't look at them when he spoke, but they all heard him. "Ladies and Gentlemen of Craphole Island. Kate is sitting still. Twenty bucks says she's on drugs and is too wasted to stand...OW!"

Another rock, a bit larger this time, had flown from inside the group, and hit Sawyer in the temple. He stopped, looking to see who had thrown it, and his eyes came to rest upon Aaron, who had another ready.

"Come on, Kid, you're on my side." Sawyer reasoned.

"Don't you be nasty to my Kate." He said in his pouty childish voice.

"Aaron! Don't throw rocks at people, you could hurt them." Claire warned him, Aaron put the rock down and went to sit beside Kate.

"I think I prefered you as a kid, Freckles." Sawyer grumbled, and Kate and Aaron looked up at him, simultaeneously sticking their tongues out at him. Everyone laughed and Sawyer disappeared again.

Kate looked down at Aaron. "I'm glad that I've got you on my side now, Kiddo." She said, ruffling his hair. He shook his head, letting the soft curls fall back into place, and giggled.

"Wanna race?" He asked excitedly.

Kate remembered their races on the beach, and smiled softly at him. She was still very tired at the moment, and she wanted to spent time with Jack. "Sorry, Aaron, I'm really tired." She said. His face fell. "But tomorrow, we'll come up with a better race than Sawyer did."

Aaron seemed satisfied with this, and Kate turned back to Jack as he wandered back over to his mother. "What?" She asked, when she saw how Jack was looking at her.

"See, you don't need any silly tests like I did." He said with a smile.

"Tests?" She asked.

"Everyone thought that the reason you turned into a kid was so that Jack could prove to himself that he would be a good father." Shannon explained.

"I take it that it worked then."

"Think about it." Claire said. "He's looked after her when she was ill, he kept her occupied and out of trouble, when she was in danger he went and found her, he made her feel safe when she was scared, he made up a story for her."

"We." Shannon intervened proudly. "We made up a story for her."

"Which was very good." Kate assured them.

"I'll still be worried." Jack said. "Like Claire said, it's natural. But at least I'll be prepared for Kate's offspring."

She elbowed him gently in the ribs, and he smiled, pulling her close again and both of them smiling at each other as they rested their hands on her stomach on top of each other. Things were back to normal again.

A/N: Want it to end here? Or do you want more? I'd really like to introduce the cause of all this change cough-baby-cough, as I've got a really clear picture of her in my head. It depends on you guys though :D
