Kate laughed uncertainly.

"You're joking right?" She asked. Jack shook his head. "But I can't… I mean we…"

Kate put a hand to her head, thinking.

"I thought…" Kate looked at Jack carefully. "I thought you used-"

"I did, Kate, but it was months old. Who knows how effective it was?" Jack said carefully. "I can't be a hundred percent sure without being able to perform an ultrasound, but it's unlikely to be a virus, not with the symptoms you described."

Kate took several deep breaths.

"Ok," she said quietly, inwardly collapsing. "I… I'm just going… for a walk…"

She stammered turning away. Jack caught her arm.

"Hey," He looked her straight in the eye. "It's ok you know."

"I know, I just… need to think…" Kate replied walking away quickly. She didn't look back until she was deep in the jungle, where she leant with her back against a tree and sobbed bitterly.

How could she, Kate, who felt responsible for two murders, the fear she drove into her mother, and felt she couldn't take care of anyone, bring a new life into the world? What kind of mother would she be? She was still uncertain that she deserved to be happy, or to be Jack… Jack. What had she done? She'd made him a dad and she didn't even know if he wanted kids. She wasn't sure if she herself wanted children. What if she couldn't take care of them properly?

Kate cried harder, sinking to the ground, scratching her back on the tree as she went. The pain gave her something else to think about but didn't distract her fully from the fact that she was going to be a mum.

Someone stumbled through the trees but Kate didn't look up.

"Kate?" It was Sawyer, she could tell from the voice. "What's wrong?"

She felt him kneel next to her and reach out, touching her arm gently.

"It's nothing," Kate managed to say through her tears.

"Well, no offence Freckles, but when you find someone crying there's usually something bothering them," Sawyer replied quietly. "What's wrong?"

"I can't… I can't tell you…" Kate said, deciding that until she was absolutely sure, no body would know about this child.

"Why not?" Sawyer pulled her hands away from her face and forced Kate to look at him.

"Because I'm a bad person!" She shouted, sobbing harder.

"Hey, hey," Sawyer held her steady as she began to sway, dizziness overcoming her again. "You are not a bad person."

"I am." She moaned. "You don't know what I've done."

"What have you done?" Sawyer asked, confused. Kate didn't reply, she just threw her arms round Sawyer and hugged him.

"I need to think," she said after a while. "If you really want to know what happened, ask Jack, but I need to be alone right now."

Sawyer nodded and Kate wandered away, through the trees. Sawyer continued to the caves and found Jack banging about in the infirmary making rather more noise than was necessary. He cursed as his he kicked a rather large rock and only managed to hurt his foot in the process.

"I saw Kate in the jungle," Sawyer said carefully. "You two had a bust up?"

"No," Jack said, looking at the mess he'd created and swearing again. "No, we're fine… it's just… nothing…"

He began to tidy up and Sawyer helped, gathering a few files together.

"Something you wanna tell me?" He asked quietly, deciding if Jack bit his head off he'd let it go. Jack didn't reply straight away. He took the files from Sawyer and put them away, before turning and rubbing his face.

"I think…" He looked around to check no one else was in earshot. "I think Kate's pregnant."

Sawyer's eyes widened.

"What? But how-?"

"We were careful, but… we have to face facts, we're on an island in the middle of nowhere…" Jack said not meeting Sawyer's gaze.

"So that's why she was so upset…" Sawyer muttered to himself.

"What?" Jack looked up sharply.

"When I saw Kate, she was in tears, kept saying she was a bad person," Sawyer replied.

"Oh god," He sighed. "I don't think I can be a dad Sawyer."

When the plane first crashed Sawyer would've been the last person Jack would've talked to about such a delicate matter. But over the past few weeks he'd grown to like and even see Sawyer as a friend.

"You?" Sawyer laughed. "Jack, the do gooder doctor?"

Jack smiled wryly.

"I'm not all good." He replied.

"Well what're you going to do?" Sawyer asked.

"Nothing." Jack shrugged. "Whether we want this baby or not it's going to come."

Jack shook his head as though he was trying to dislodge water.

"I don't even know if she is pregnant," He said quietly. "I mean she was sick this morning and the past few mornings, but it could be anything."

Sawyer nodded. He looked over at the water hole where Hurley was filling water bottles.

"If you ever need to talk, you know where I am," Jack nodded gratefully.

Kate sat in Sun's garden alone. Sun must've gone to do something else because she wasn't there when Kate stumbled in. She was now picking weeds to take her mind off things. She really didn't want to think about the baby that might exist. She didn't want to have to think about the fact that in nine months time she might have to be the mother she knew she couldn't be. This child deserved a good mother who hadn't murdered people and who wasn't stranded on an island in the middle of nowhere with almost no hope of rescue.

Kate pulled another weed, adding it to the ever-growing pile. A sudden thought came to her, floating out of nowhere. What if Jack didn't want this child? There was no way of getting rid of it. What if he disowned her and refused to have anything to do with her? Feeling even worse she stood up, subconsciously rubbing her stomach, and headed towards the hatch.
