Jack rested his head tiredly as he leaned against a tree. He sighed, shutting his eyes tightly. Kate did the same, putting a hand to her hip.

"You...tired...?" Kate asked, between pants. Jack opened his eyes and nodded slowly.

"I...can...see that you are...too," Jack said, smiling. Kate laughed.

"You two think you're...tired?" a voice asked. Startled, Jack and Kate turned around, and saw Sawyer, panting as well. He frowned, looking at them as if they were crazy. "You have no clue what tired is!" He put an arm on the bark of a tree and leaned forward, trying to catch his breath.

"What are you doing...here?" Jack said, trying to regain his breath as well.

"Why are you following us?" Kate asked, raising an eyebrow.

"Hey, hey, the way ya'll say it as if I did some sort of crime. Jeez, lighten up... what did I do? Well, no, forget that question." Sawyer sighed, then smiled, a silly expression on his face. "Whatcha' two walking out here for? You two plan on doing a little somethin' in the caves or some stuff like that?" He looked at Jack and smiled. "You plan on going there with your girlfriend, huh?"

"...Kate?" Jack said, raising his eyebrows.

"How'd you know I was talking 'bout her?" Sawyer said, his grin widening.

"When you-...lucky guess," Jack stammered slowly.

"Sawyer, what do you want?" Kate asked.

"Oh, I'll leave when I get what I came for," Sawyer assured them, nodding.

"And what's that?" Jack asked, frowning.

"A little something," Sawyer said, smiling once again. Kate sighed, rolling her eyes.

"Hey, there's no rolling eyes at me," Sawyer said, alert. He sighed. "Yeah, I'll, uh...just be, well, 'lurking' around somewhere." He winked at Kate. "'Somewhere'..."

Jack and Kate exchanged unreadable glances.

--------------------
A few minutes later...

"So... what was all that?" Kate asked, smiling.

"What was what about?" Jack asked, frowning. He brushed against a branch as he walked past it.

"The 'nervousness'," Kate cleared for him, her grin widening. "And don't try to lie, Jack. I can easily tell when you're lying or not. Believe me, your little 'lucky guess' wasn't at all a guess... Right?"

Jack said hesitantly, after a moment, "No."

"Ha, thought so," Kate said, chuckling.

"And when was I being nervous?" Jack said, raising an eyebrow confusedly.

"Trust me," Kate said, sighing that Jack wasn't getting what she was implying, "whenever it's just the three of us: you, me, and Sawyer, you're a nervous wreck. Trust me, Jack. A completely nervous wreck."

"Well, you don't have to rub it in," Jack said, chuckling. He shrugged. "Maybe it's a habit."

"Why? Being nervous around the person you-," Kate began. Then she immediately stopped, realizing what had just slipped out of her mouth. She gasped, surprised at herself.

"The person you what?" Jack prompted.

"Uh...you know, when I'm around you," Kate began, smiling sheepishly, "things just sort of slip out of my mouth. You know...things that aren't supposed to..." Then, after an awkward pause, she frowned. "Damn. Just like I did now..."

"See?" Jack said, laughing aloud. "You're nervous around me, too!"

"Oh, so you were thinking that?" Kate said, a playful look of disbelief on her face. She rolled her eyes again. "And you didn't happen to tell me?"

"Hey, you keep things from me, so I have things that I keep from you," Jack said, smiling. Then he stopped walking, and frowned. "I-"

"Ha!" Kate said, jumping up happily. She pointed at Jack accusingly. "You also have things that slip out of your mouth! Now. Tell me. What things do you keep from me?"

"...Things," Jack said, looking away. He looked down. "You know, Kate, we should be heading back now..."

"Jack...!" Kate said, sighing with disappointment. Jack always had to ruin the fun. She put a hand on his shoulder. "Please, Jack, it's still early. Look up at the sunny sky! Don't try to butt your way out of this one."

"But-" Jack began.

"No 'buts', like I said," Kate said, smiling proudly. Jack rolled his eyes.

"You're like my teacher now, huh?" Jack said. Then he laughed as he said, "So, Ms. Kate, what now?"

"Okay, I demand you to tell me what you keep from me," Kate said. "Your secrets. I'll do the same in return. But, you're first. Okay?"

"Fine," Jack said, shrugging again. "I will."
