Jack stepped forward, because he was the leader and everyone always listened to him.
"Ana," he said. "And Arzt," he paused dramatically. "Are together."
There were gasps of astonishment and terror, and a random girl fainted with a weak scream. Ana rolled her eyes.
"Oh, come on, there are heaps of couples on the island, why are you all shocked?"
Kate glared at her through tears.
"Duh! We've explained this already! If you look at all the other couples, you'll notice they look hot together. All of them, but you!"
A murmur of agreement went through the crowd, and people pulled their partners closer, proving Kate's point.
Ana let go of Arzt's hand and walked up to Kate.
"Shut up. You think you can just tell us what we can and can't do. You think that you're better than me just because you have a super-sexy boyfriend. Well let me tell you, Jack doesn't -
"Don't talk about Jack, btch! You don't know him!"
"I know him better than you think, girly. I bet he never told you about our little... meeting before the flight, huh?" (Of course Ana is gonna exaggerate everything about that dumb drink at the airport)
Kate stood in shock for a second. Ana grinned.
"Didn't think so. I'm glad I at least have trust in my relationship" she said smugly, turning to walk away, but was stopped by Kate's fist flying out and hitting her hard in the jaw. She looked up to see Kate's eyes shining with rage.
"Shut up, btch. Don't ever talk about Jack, or me, ever again."
The crowd cheered, of course they were on Kate's side. Kate turned away, back to Jack. Ana stood up, raising a hand to her jaw gingerly.
"You remember, don't you Jack?" she said loudly. Kate stopped and turned back to look at her in disgust.
"Tequila and tonics... that stuff's pretty strong, huh? But then again, you probably can't remember much after that, seeing as when we -
"Shut up!" Kate screamed, running at Ana and knocking her to the ground. She punched her in the face, then Ana pushed her off and rolled over then punched her. Kate kicked her in the stomach, then jumped on her again. Jack and a couple of other people ran forward to separate them. Jack and Sayid grabbed Kate's arms and pulled her off Ana. Arzt finally came and helped Ana up. She smirked at Kate, as if she had won or something. Kate glared at her.
"Let me go." she told Jack and Sayid.
"No, Kate." Jack said. Kate struggled against their hold, watching Ana retreat down the beach, Arzt's arm around her shoulders.
"I wanna kill her." Kate murmured. "Did you hear her talking about you? How dare she make up lies like that!"
"Uh, Kate... she, um, she wasn't really lying"
Sayid had disappeared, sensing they needed to be alone.
"What?"
"In the airport... we did have a drink together" Kate stared at him, then turned away in disgust. "No, but that was all! I swear, Kate, I don't know what she was on about, nothing else happened!" Jack said quickly. "How could it, Kate?" Have you seen her? She's so... manly..."
Kate suppressed a laugh.
"Okay" she said and turned back to him. "I believe you. I... I trust you"
Jack smiled. "I trust you too, Kate." he pulled her close into a hug. "Now, how about we forget about those two, and think about us?"
Kate smiled. "I'd like that" she said and her and Jack linked hands and slowly walked down the beach towards the sunset, away from Arzt and Ana.
