A/N: Thanks for the reviews! It's time for prom!

Chapter 23: Prom

Everyone had taken the news of Jack and Kate's engagement and were overjoyed. Now, it was prom night and the young couple was excited. Diane was helping Kate get ready, while Jack was putting on his tux.

"Someone looks nice!" Claire smiled as she came in his room. "Kate's going to be thrilled."

"I'm excited to see her too." He was having problems with his tie, so Claire went to help him with it.

"Did I tell you we were on the phone for 4 hours straight talking about your proposal?" She asked. "I didn't know you were so romantic." She teased.

He just rolled his eyes at her. She finished his tie. "Thanks for the help sis. I hate ties!" He looked over at her and saw a sad expression. "I wish you could go tonight. You've always wanted to go to prom."

"That's OK. I have Aaron to stay with. Plus, I'm not supposed to do too much after having a baby."

Jack nodded, but Margo soon called them.

"Jack! Kate's here!

When Jack came down the stairs he saw Kate in a beautiful green spaghetti strap dress. It showed off her eyes, her hair was in an updo, and her ring sparkled with it.

"Wow. You look absolutely beautiful." Jack said as he kissed her.

"And you're so handsome." She smiled.

"Let's get some pictures." Margo said as her and Diane took some.

Claire came down holding 3 week old Aaron. "Someone wants to see his favorite aunt and uncle before they go to prom!" She held her son so he could look at them.

"Hi Aaron! You're getting bigger. We wish you and your mom could go." Kate spoke to the infant.

"Wish us luck buddy?" Jack said as he touched Aaron's little hand. He nephew grabbed one of his fingers. "I think he just did!"

The couple moved towards the door. "Have fun you two!" Margo said.

"Remember to stay safe." Diane added.

"Let me know who gets in a fight!" Claire said.

Kate laughed. "We will."

Margo and Diane looked at the younger blonde. "What? Someone always gets into a fight at prom." Claire explained.

So far, everyone was having a great time. Jack and Kate met up with their group of friends for dinner, then they all headed to the country club. It was decorated nicely with a Hawaiian theme. Ana, wearing a black dress, was dancing with Sawyer; while Hurley was dancing with Libby, who was wearing a light blue dress. Jack and Kate were sitting down taking a break from dancing.

"Kate?" A woman called out. "Jack?"

They both turned their heads and saw Sun Kwon and her husband Jin. "Sun!" Kate said as she hugged her friend. "Jin! What are you two doing here?"

"Mr. Locke needed chaperones, so we came." Sun and Jin were 2 years older than the rest of the group, but were still close friends. They hadn't seen much of each other since the Korean couple married.

"That's great." Jack smiled. "It's been such a long time since we last saw you. Kate and I are engaged!"

"Congrats!" Jin said.

"Can I see the ring" Sun asked and Kate held out her hand. "It's so beautiful! I'm so happy for you two! And we have news as well. Jin? You want to tell?"

"Sure. Sun and I are expecting!" He beamed.

"That's awesome!" Kate hugged her friend again.

"It looks like we all have something to be congratulated for." Jack added.

"Sun! You should see Claire and Aaron! He's so adorable!" Kate excitedly said.

"I will and maybe I'll get some practice." Sun replied.

Suddenly, there were shouts. "Boone! Get your hands off of me!" Shannon yelled.

"Shan, stop it. Sayid and Alex don't need to know." Boone replied.

Everyone looked at the two step-siblings. Shannon was obviously drunk.

"What? That I slept with you!" She didn't even realize people could hear her.

Alex Rousseau, Boone's girlfriend, slapped him and ran out in tears. "Alex, wait! Let me explain!" Boone ran out after her.

Sayid Jarah, Shannon's boyfriend, just walked out and wouldn't talk to her. Sawyer was hysterically laughing and Ana hit him to make him stop. Shannon ran out of the room in tears, with Sarah and Mark chasing after her.

"Wow." Sun said shocked.

"Did that just happen?" Jin asked.

Jack just nodded his head and Kate said, "Claire was right. There's always a fight at prom."

Later on, Jack and Kate were slow dancing. "Claire's missing a fun night." Kate said.

"Well, I did something to help her out." He replied.

"You better tell me." She teased.

He whispered in her ear and her smile grew wide. "Oh Jack! She's going to love that." Kate kissed him, now also knowing why another friend wasn't there.

The doorbell rang and Claire answered it. "Charlie!"

He had a radio and said, "Jack and I thought you could use some cheering up."

She hugged him. "Come on in. I was just feeding Aaron."

He came in and saw Aaron in his car seat. Claire was using it to have him in a sitting position while he ate. The baby stared up at him as he said hello.

"What's with the radio?" Claire asked.

"It's your prom dance!"

She looked at him confused.

He plugged it up and said, "Come here Claire."

She looked skeptical, but moved towards him. He pressed play and "Collide" by Howie Day came on.

Claire put her arms around his neck as Charlie put his around her waist. The moved closer as they danced.

"Thank you Charlie! For everything." She was having new feelings emerge.

"Your very welcome love." He stared straight into her blue eyes.

They leaned in and kissed each other for the first time. It was a soft kiss and they both enjoyed it. They smiled at each other when they parted. Claire and Charlie looked over to Aaron who seemed to be smiling and moving his hands.

"I guess he approves." Charlie said as Claire giggled.
