Kate kept running forward, into the jungle. Laughing, she outstretched her arms and cried out gleefully. Jack had never seen her like this before, so he was pretty surprised.

"Where are you going?" Jack asked when Kate stopped in front of a tree. She simply turned around and flashed a grin at him, saying nothing more. Well, she actually didn't have to. Jack knew what she was about to do.

As Kate climbed up the tree, she could hear Jack chuckling below her.

"Just like I found you!" he called up to her.

"Hey," she said, once up the tree. She sat on a thick branch, "Want to come up?"

"Me?" Jack asked. He backed up. "No, no it's okay." He chuckled lightly. "I'm not an amazing climber like you, ya know."

"Oh, c'mon," Kate pleaded, putting her hands together and intertwining her fingers. "Please…" Jack sighed and rolled his eyes, finally giving up.

He started to climb up the tree by grabbing branches, and planting his feet on openings or rocks. He was doing pretty well for a beginning, and was up to Kate in no time. Kate rolled her eyes and crossed her arms.

"Right," she said, "a 'beginner'." She laughed. "Let's see if you can make it up with me right there." She pointed to the top of the tree, where the branches got thinner. Jack bit his lower lip, and looked up to where Kate pointed, then looked back at the ground.

"I don't think that's such a good idea," Jack said, resting a hand on the branch he was sitting on. "What happens if you fall? I mean, what happens if I fall?" Kate giggled.

"You won't fall if you concentrate," she said. "I always concentrate. That's how I'm so good at it. I'm a pro," she said, pretending to be all that. "Anyways, c'mon, let's go. I'll race you to the top."

"Hmm," Jack said, rolling his eyes, "I wonder who'll win."

They started going to the top, when it became so thin that only one of them could go up at a time.

"What the hell are you two doin'?" a voice called out. Kate and Jack turned around. It was Sawyer, of course.

"What does it look like?" Kate asked, smirking. She turned around, and started to climb the tree again.

"Ya' know," Sawyer said, putting his hands on his hips, "if you fall, Freckles, guess who you're going to topple on over?" He laughed out loud. "Now that will be funny."

Not paying any attention, Kate continued climbing, and one of her feet slipped. She cried out, but didn't let go.

"Don't let go!" Jack cried out. He looked down at the ground. "Look how high we are! Kate, maybe we should stop!"

"No!" Kate protested. "We're almost there! There, I'm here!" She held onto the tree, and looked up in the sky. The tree they were climbing on was unbelievably taller than the other ones, so they had a clear view of the beach, the mountains, and the sky. "Wow," Kate mumbled, "it's beautiful."

"Whoa," Jack said, once he was right below Kate. He scooted up a little to see better. "That is amazing." He looked down at the ground and sighed. "You know what I'm afraid of doing now?" He looked at Kate, who shrugged down at him. He said in a flat tone, "Going down."

Kate chuckled, then said, "Let's go down now, Jack." But as she said this, when they were already going down, she happened to slip her feet again. But this time, she wasn't holding on to the branches. She toppled on Jack, who caught her arm. He grunted in pain, then started sliding down slowly.

"I have to let got! This isn't as pleasant as it looks!" he cried, and saw that Kate nodded. He let go of the branches and they hit the ground with a thud.

"I'm so, so, so sorry," Kate apologized. "I shouldn't have let you climb that tree."

"Nah, it's okay," Jack said honestly, massaging his wrist. "It was quite an… adventure." They heard Sawyer chuckle. He was still there, and now he was laughing at both of them. Kate rolled her eyes.

"I bet you can't climb a tree," she bet Sawyer. Jack rolled his eyes, chuckling.

"Now, Kate," he said, putting a hand on her shoulder, "let's not start with that again."
