A/N: Thank you, thank you thank you for all the reviews. Sorry I haven't updated in a while. I was feeling a little of and then I am about to start a new school in a few weeks which is making me super nervous. Anyway, I know all of you want me to reveal's Kim secret but I felt like I need to write this chapter up first because I felt like it might be important later on and it might explain some things about Jack and Kim. Plus there are Jack and Kim moments in this, so it should be enough right.

Oh please take note that all this scenes are from their past but it may have relations to the story. I'm still trying to get my bearings on the story. I know what I want, but with every chapter I write, it's getting harder and harder as I have so many more ideas.

Anyways enjoy…

Not Since You

Chapter 5: Flashes

"Promise me no matter what, we will always be best friends."

Those words came out of Kim's mouth before she had time to stop them. It was stupid to say it out loud. They knew where they stood. Jack has and always be her best friend, and Kim knew that. But that didn't stop the fifteen year old from voicing her thoughts.

They were the only ones in the dojo. Training on dummies. Well to be more precise, Kim was stretching and watching Jack try a new move on a dummy. Rudy was trying to get the other three boys, away from whatever they were up to, to the dojo for practice.

Jack looked up from where he was and gave her a smile. It made her feel as if her question was not stupid, as if he did care that she wanted to be best friends no matter what happen That they would continue to support one another's choices regardless of what they thought.

As if no matter whatever happened years on, she would always have him.

"Promise."

…

"Jack!" Kim squealed.

It was her sixteen birthday. She wanted to celebrate it by just relaxing. Watching a movie at home with her closest friends. After all, she had been having a hectic week with cheer leading and the school news team. Jack, however, did the opposite of what she wanted. The backyard of her house was covered with decorations. There was a large cake and stack of presents. A DJ with a rather impressive system spinning some tracks. The whole school seemed to be there surprising her for her birthday.

Kim turned to Jack after her initial surprise. Jack had tried to put on a smirk but Kim could see he was grinning, clearly pleased that she was happy.

"I know it's not exactly what you wanted but happy birthday," Jack said as he pulled Kim into a hug. Kim did not even try to hide her smile. As soon as the hug started, it ended, as all her other friends started to claim her.

Kim's sixteen birthday was not at all what she wanted, it was so much better. She had danced the night away with everyone, talked with her closest friends and even saw her favorite cousin. It was a fun birthday in which her mom surprised her by getting her a brand new laptop. She was having a good time. During the conversation with her cousin, she sneaked a pick at Jack who had his arms around Heather Clark.

They have been dating for two months. Kim could see Jack smile as he dipped into kiss Heather Clark on the lips. It gave her a strange sensation. Something Kim never had experience before.

"You like him," her cousin said in a matter of fact voice that Kim had to roll her eyes.

"Of course I like him, he is my best friend," Kim said.

"That's not what I meant," her cousin replied, walking away before Kim could retort back.

Kim was left speechless. Jack was her best friend. She could not have feelings for him. That was unthinkable. Sure, there were always those movies and t shows that have best friends falling for one another but those were jut movies. Fake as in not real. Some of her friends teased her about Jack, but her feelings were strictly platonic. Right?

Kim shook her head getting rid of the thoughts. Tonight was not about revelations, it was about having a good time.

Soon, the party ended. Kim smiled and said her thanks as she watched the last of them leave and closed the door. She walked back to the backyard to see her mom and Jerry outside cleaning up. Milton and Eddie had to leave the party halfway while Rudy only stayed at the beginning of the party and Jack went to drive Heather Clark home.

"Thanks again for the party guys," Kim said to the two of them.

"We can't take full credit. Jack was the one who organized it," Kim's mum said, "I just allowed it. Happy Birthday sweetheart."

And with that Kim's mom pulled her into a hug. Kim hugged back before helping out on the cleaning. There were paper cups and plates everywhere. Tissues and streamers were scattered. It looked as if New Year's day threw up on her backyard. Kim started picking up the used paper cups.

Halfway through the clean up, Jack came back and started helping.

"Shouldn't you be at Heather's?" Jerry asked.

"Nah, her parents are home," Jack said before adding, "Plus I want to help out here."

Jack gave Kim a huge smile and Kim could not help but grin back.

…

"What happened?" Kim asked as she walked into Jack's room.

Jack's room was a little untidy. There were some clothes at the floor. His study table was filled with books and papers that he deliberately did not sort out or put back to his shelf. Kim could call him lazy but then again so was she. They were teenagers after all.

It had been four months after her sweet sixteen and Jack had been ignoring her calls, text and messages for the past two days. She tried to give Jack space but there was something that made her feel as if they needed to talk now and not put it off.

Jack was lying, facedown, on his bed mumbling something that Kim could not quite hear. The sixteen year old blonde decided that she had been patience with Jack enough and rolled him over so that she could see his face. Kim was so sure she was looking exasperated, irritated and worried all at the same time.

"Now, I ask again; what happened?" Kim repeated placing her hands on her hips.

"Heather," Jack said before groaning.

Kim kept quiet, knowing that Jack was going to explain. Jack and Heather had been fighting a lot lately, she never knew the topic of what her best friend and his girlfriend was fighting about but knew that it was something serious.

"She kept accusing me that I was seeing you secretly," Jack said before sitting up and looking at Kim straight in the eye, "I mean that's crazy right? You're like my best friend and we would never, you know, get together.

"Yeah," Kim agreed, trying to keep her voice steady.

In all honesty she was confused. Ever since her birthday, what her cousin said had been on her mind. Did she like Jack? Of course. But more than a friend? She was not sure. She was only sixteen. Who knows what love really is at sixteen? Sure she had her fair share of boyfriends over the years and had heard 'I love you' countless of times. But that could have been puppy love which does not count or infatuation. So in all honesty, she had no idea what Jack meant to her.

But it did put her off that Jack seemed to think that him and her would never work out. They were both stubborn as hell and they knew each other in and out. Well at least Kim thought they did. Was the idea of being with her that repulsive? Was she that gross or just too much of a friend for Jack?

"See, you agree," Jack said, obviously not noticing Kim's line of thoughts, "It's just so frustrating that she won't even trust me with you."

And as clearly as Kim could see it, the topic of the argument had been her. Was Heather really jealous of her and Jack. All they had was friendship, right? Kim let Jack vent on and on until she had to leave. She gave no advice knowing that all he need was someone to listen to. And besides, she had no idea on what to say anyway.

The next day in school, Kim received a text message from Jack: I promised Heather that I would stay from you for one week . I'm sorry. Kim frowned but nevertheless accepted it.

By the end of that week, Heather and Jack broke up.

…

After Heather, Jack didn't date for a while. Kim found that she was spending more time with Jack, if that was possible. Her mind tried to wrap around her thoughts and feelings. She felt that she should stay away from Jack until she knew exactly what she was feeling. Chances are someone would be getting hurt.

But she didn't. Everyday Kim got more and more confused, trying to battle out her feelings on the hours she was not with Jack. She still had no idea how she felt.

It was on one particular incident that changed everything.

She was sick with the flu. Her nose was runny and her eyes were puffy and she felt so horrible. Her mom made her stay in bed all day with no visitors so she was bored out of her mind. And then just 30 minutes later her mm went up to give her a package saying that it was from Jack. Kim opened it up and stared shock. Inside was the one movie she never told Jack about but watched it as a child, when she was sick, when she was bored or just when she wanted to. The last and only time she told Jack was when they first started becoming friends.

It honestly touched her that Jack remembered. Her sick week passed by quickly. Kim was walking to Jack's locker when she spotted him with Donna. Kim watched finally realizing the truth. She wanted a sort of claim on Jack and she did. He was her best friend. But anything above that was a little blurry. It was like jumping into a lake. You don't see the bottom of the lake unless you plunged in.

Whatever it was, she would have no chance plunging in now. Another girl had beat her to it.

Done. Kind of short. I promise to make the next chapter longer
