Trying to line up episodes but that's a lot harder than I initially thought. But anyway, a lot of this is taken straight out of Lost season 2
After confessing their feelings for each other, Jack and Kate sat together on the couch for a while, simply enjoying each other's company, Jack merely enjoying seeing Kate awake and looking better. As much as it pleased Jack to see her looking so much better, it also concerned him, knowing that malaria often comes in bursts, making its victims feel perfectly normal for a while before striking them down once again. Eventually Jack's need to take care of Kate came to the front of his mind and he once again slipped into his role as her doctor.
"Kate, as much as I wish you could take what I am about to say as a follow up to our confessions just now, it really isn't meant that way, but I need to examine you now," Jack said with a slight smirk.
"Jack Shepard! Get your mind out of the gutter! But uh…do I need to take my clothes off?" Kate asked with a flirtatious smile
Jack just gaped at her for moment, letting the idea sit in his head for moment before he responded, "Not this time Kate, but I promise, when you are well, there will come a time where my examination of you will definitely involve you taking your clothes off."
Kate blushed and moved to head back into the bedroom, Jack following her. As soon as they walked into the bedroom, Jack was all business, realizing that it was going to be difficult for him to be strictly professional where Kate was involved now but knowing that she did in fact need a doctor at the moment.
"So how are you feeling now Kate? Physically?"
"I have a never ending headache and overwhelming tiredness but I feel so much better than before."
Jack nodded, acknowledging her answer before proceeding, "Are you having any trouble breathing?"
Kate shook her head
"What about nausea?" Jack asked
"Nope, not today anyway," Kate answered.
"Ok, that's good, what about your vision, any problems there?"
"No, I can see fine. Are these things that I should be worried about Jack?" Kate asked, getting a little paranoid about the things Jack was asking about.
"These are worst case scenarios Kate. I don't think we have anything to worry about but if you do experience trouble breathing, severe headache, blurry vision, weakness, or severe nausea, you need to let me know right away. I know you don't like to admit when you aren't feeling well but Kate, I'm serious about this." Jack told her while looking her straight in the eye.
"Ok Jack, I promise. You're kinda scaring me here," Kate responded
Jack reached out to feel the glands under her neck as he spoke to her, "Kate I'm sorry, I don't mean to scare you, I just want to make sure I'm doing all I can to help you. And besides, we all know my bedside manner is a little lacking," Jack chuckled
"Ok Jack, I know and actually, I think you have a pretty stellar bedside manner. /but I'd think even better of it if you let me take a walk. I'm going crazy here," Kate pleaded with Jack as he checked her pulse.
"Kate, I don't know if that is such a good idea, I know you feel better now, but malaria is an odd thing. It comes and goes in spurts. You feel better but then suddenly it'll be back and hit you out of nowhere. The last thing I want to do is scare you, but I want to be honest with you here and the truth is that is probably not over yet."
"So then we should take a walk while I'm feeling better. We don't have to go far but Jack I need to know that the world is still out there. I need to see the sky and the trees. Please Jack, you'll be with me if anything does happen." Kate was full on begging now; giving Jack the saddest face she could muster.
Jack simply could not resist her begging. Even though he knew that it was probably not a good plan, he couldn't say no to her request. In the back of his mind, Jack suddenly realized why doctors weren't supposed to treat their own loved ones, because they think about making them happy and not just making them healthy. "Ok, Kate, we'll go but not far. We can walk down to the beach and then come back. And if you feel the slightest bit worse than you do now, you tell me immediately. Promise me or we aren't going."
"I promise!" Kate said brightly as she rose from the bed.
Jack gathered a few medical supplies in his bag, just in case, and he and Kate walked out into the main room of the hatch, finding Locke reading by the computer. Jack didn't want to even acknowledge his existence but knew he needed to keep peace as best he could. "John, we're going for a short walk. If you need anything, I'll be at the beach, are you okay here?"
"Of course Jack, I've got a handle on everything," Locke replied
"I'm sure you do," Jack mumbled, too low for Locke to hear. He then took Kate's hand and the two of them exited the hatch together, leaving Locke and Henry Gale as its only occupants.
Jack and Kate followed the path down to the beach, stopping often to allow Kate to rest due to her weakness. Jack was quite pleased with how well she was doing at the moment. They maintained conversation on the walk, each learning new things about the other. They reached the beach without any major incident. Upon seeing Jack and Kate emerge from the jungle, several people walked over to greet them. They talked to the group for a few minutes before moving off to sit by the beach. Jack led Kate to sit down and then went to go check on Claire and Aaron since it had only been a few days since Aaron had been sick and Jack had been preoccupied with Kate. After Jack walked away, Sun came to sit beside Kate.
"Hello Kate, you are looking better than the last time I saw you. It is good to see you again."
Kate looked up at who had joined her and smiled. She and Sun had developed a rather deep friendship in their time on the island, mostly through gardening. "Hi Sun! It's good to see you too! And thank you for helping me, Jack told me."
"You are welcome Kate," Sun replied.
Kate heard Sun gasped and looked over at her, noticing that she looked a little green. "Oh Sun, you're not sick too are you? You don't look so good, should I get Jack?"
"No! I mean, I am fine, no reason to get Jack. I am not sick. It is, just, you must not tell anyone what I am about to tell you," Sun said, looking Kate straight in the eyes, begging her to consent.
"Of course Sun, you know you can trust me, what's wrong?"
"I am not sure, but I think I am pregnant," Sun confessed
"Sun! Congratulations, I suppose?" Kate inquired
"I would be excited, I think. Sawyer gave me a pregnancy test but I have not taken it yet."
"Would you like me to wait with you?" Kate asked
"Would you?"
"Of course. You go do what's necessary and come back and we will wait together."
Sun then got up and went into the jungle, returning a few minutes later. The two women sat together in silence, waiting for the results. When the time was up, Sun picked up the test and realized that she had gotten a positive result. "Do you think this is accurate?" Sun asked
"I'm not sure, but I know who would know," Kate implored, asking Sun for permission to tell Jack. Sun nodded, knowing that the doctor could help her more than anyone right now. Before either of them could move to get him, Jack approached the two of them. "Hello Sun," he greeted
Both women looked up at him and then back at each other. Jack could see the guilt written on their faces, knowing immediately that something was up. "Okay, what's going on?" Jack asked
Sun held up the pregnancy test, allowing Jack to see that it was positive. "How accurate is this?" She asked
Jack was taken aback for moment, realizing that on top of everything else going on, the island had just acquired another pregnant woman. "It's pretty accurate, You might get a false negative in the first week, but a positive is a positive. Congratulations Sun."
"Please Jack, you can't tell anyone," Sun begged
"Don't worry Sun, doctor patient confidentiality, remember?" Jack replied with a smile
With that, Sun took her leave from the other two, leaving Jack and Kate sitting together on the beach. Jack could tell that Kate was beginning to get tired and decided that it would be best to allow her time to rest before making the walk back to the hatch.
"Hey, how about we go lay down in my tent for a while? Nothing much happening out here right now anyway, besides a poker game between Sawyer and Hurley, which I'll admit is quite the sight, but I think you could do with a nap." Jack suggested
"Actually, a nap sounds pretty good. I'm very tired all of the sudden and my headache has gotten a bit worse."
"Thank you for telling me that Kate," Jack said sincerely. He then helped her to stand and they walked toward his tent. When they arrived he helped her to lay down and he climbed onto the makeshift bed behind her, both of them falling asleep within minutes.
Sometime later, Jack was awoken by what sounded like someone choking. He sat up immediately and realized that the choking sound was coming from Kate, who was awake and looking at him with terrified eyes.
"Jack…I…I…can…can't…bre…breathe" Kate squeaked out
Jack saw her struggling to breathe and immediately began to panic. He reached over and grabbed her, helping her into a sitting position. Jack noticed that helped her a little bit but not nearly enough. In that moment, Jack was cursing himself for listening to Kate's desire to take a walk. Kate reached out her hand, groping in a blind panic for Jack's hand. He immediately took her hand and sat her back against his chest. Hearing Kate wheeze and struggle to breathe was almost sending him into a panic attack.
"Jack…Jack…please…I'm…I'm so…sca…scared…hhhelp…me." Kate said in a heartbreaking voice.
