Wow, thanks so much guys, I'll try and put all of your suggestions to use in this chapter. Again, please review, because otherwise Ill have no idea what I'm doing wrong (specifically, not just all of it.) Big shout-out to alexis, the flashbacks are coming in this chapter (They're in italics). And to SweGuy, Ryan is coming into the story – if it's not in this chapter, then definitely the next.

Oh yeah, the disclaimer from last time still applies. I mean, it's pretty obvious that I don't own the OC, otherwise, why would I be writing here?

Tears dripped down Summer's cheeks as she flicked through the photos of her and Marissa. From being little kids, off to school camp with each other in primary school, to their school musical being the princesses, to their first double date, to them sunbaking on the beach. But all of the photos had one thing in common - in all of the photos, there was no doubt that Summer and Marissa were best friends.

"I wish we still were..." Summer murmured quietly to herself.

The pair walked along in silence. The sky was growing darker, but the two didn't want to leave. Marissa looked over to her left, where he was standing. She really did like him...but she wasn't sure if it was love. But if it wasn't, why was she here, now?

"What's up?" He asked.

"Nothing." She said, as she pulled him out of the shadows to stare into his eyes. His deep, blue eyes. She decided that it must be love, because otherwise, why would she be cheating on Ryan?

Above the pier, was Summer's balcony. She was outside, on the phone to Seth as she looked down to see the unmistakable figure of Marissa. She was holding hands with somebody hidden by the shadows, and Summer assumed that it was Ryan. Summer wondered why they were there – nobody really came to this pier, and Ryan & Marissa had certainly never come here before. Just then, the guy stepped out of the darkness and the remaining sunlight shone on his face. Summer gasped – that wasn't Ryan! She thought that there must be a mistake – the two mustn't be a couple. But then, Summer's worst fears were confirmed, as Marissa pulled the guy into a kiss. Summer dropped the phone and walked over to the railing. She didn't even hear Seth calling her name through the phone as she watched the two, desperately trying to think of some other explanation for what was happening. But even she knew there was none.

Summer went to ring the doorbell of Jimmy Cooper's house the next morning. He opened the door on his way out, and told Summer that Marissa was in her room. She walked into the hallway and took a deep breath. Her footsteps echoed on the tiled floors.

"Dad? Is that you?" Marissa yelled as she walked into the room.

"Oh Summer, hey! What are you doing here?"

"Umm...Marissa, I have to talk to you about something."

Marissa didn't like the serious look of her friends face.

"Uhh, sure...sit."

Summer and Marissa sat on the couches. Summer took a breath and closed her eyes for a second.

"Marissa – I saw you last night...on the pier...with...a guy...who wasn't Ryan."She said slowly.

Marissa looked shocked.

"How dare you think that I would cheat on Ryan! Why were you stalking me?! How can you accuse me of this!" Her voice rose with every sentence.

"Marissa, I know what I saw! What do you think you're doing? I thought you loved Ryan?"

Marissa stood up and yelled at Summer.

"You're lying! If you think that then, then...you must be cheating on Seth!"

Summer was absolutely shocked. "What?!? That doesn't make any sense – just because you cheated on your boyfriend, that doesn't mean I cheated on mine!"

"Of course it does! I mean, you're a bigger slut than me, so you will cheat before I will!"

"I can't believe you! How can you say that! How can you even think that! I thought we were best friends – but, obviously not if you think that about me."

Summer turned and ran out of the room, determined not to let Marissa let her see her crying over this.
