Summary: Summer, scared at the intensity of her relationship with Seth, left him four years ago. Since then she's been all over Europe. Finally, four years later, she wants to return home to Seth. Funny when she does, he's engaged. Not like that's going to stop Summer.

Seth felt 19 again. Granted, he was only 25, so he hadn't been 19 all that long ago, but it seemed like forever. And now he was 19 again.

They were getting bored. There was only so much time you could spend sitting on a beach with someone, when all you really wanted to do was go rip their clothes off and have (more) crazy sex.

So Summer had called Marissa and coaxed her and Ryan into meeting them in LA for the night, and Marissa and Ryan, presumably eager to see how their carefully planned reunion was progressing, had agreed to join them. And now, they were at some club, that apparently was the new LA hotspot, dancing and getting drunk, just like they did when they were all 19.

He and Ryan were sitting at the table they had managed to grab, while the girls were in the bathroom.

"So what the hell happened yesterday?" Ryan asked.

"I don't know man. I was trying to be adult and mature about this. I brought her here with the intent of talking to her. You know, telling her that she and I have to be done, I'm definitely going to marry Molly in a week and a half, but I didn't exactly get there."

"Let me guess. You got in her pants instead."

"You catch on quick Ryan. That's a good skill to have."

"Molly's gonna find out man. That woman's like a shark. She lives to find out stuff like this."

Seth was planning on responding, but he caught sight of Summer and Marissa making their way back towards the table.

"Cohen." Summer said, sounding very much like she had in high school. "Bet you can't out drink me."

"Well what are we wagering?"

Summer leaned in very close to his ear and whispered something that neither Ryan or Marissa could actually hear. They could only guess, based on the look on Seth's face.

"You're on." He told her. They made their way away from the table. As soon as they were out of earshot, Ryan pulled his chair over to Marissa's. "Maybe we shouldn't let them do this."

"What?" She asked. "Get drunk and have more sex?"

"Yea. I'm worried about him, Marissa."

"They're big kids, Ryan. They can take care of themselves."

"Marissa. Is this crusade to get rid of Molly because you want to help Seth make the right choice, or because you miss Summer and you want her to have a reason to stay here?"

"It's both Ryan. You know she's not the right girl for him?"

"But is Summer? She left him in a hospital bed."

"Ryan, look at them." She said, gesturing towards the two of them, standing at the bar. "You don't fall in love like that twice."

Ryan looked. Seth was looking down at Summer, smiling in a way Ryan hadn't seen him smile in a long time. They were arguing in the way only they could, and even across the crowded club, Ryan could see the way Seth was looking at Summer, and the way she was staring back at him.

"Why are you always right?" he asked, turning back to Marissa.

"So you'll help me get them back together?"

Ryan really wanted to say no, this is ridiculous, we're not in high school anymore, but he knew that, with, or without his help, Marissa would carry on with her plan. "Whatever you say." He told her, smiling.

Seth wasn't sure exactly how many shots he had taken in the last hour, but it wasn't more than Summer. "So you win." He said.

"I always do." She said firmly. "Now there's an empty hotel room that seems to be calling our name..." she trailed off.

"Summer, we shouldn't." Seth said, feeling guilty. "Molly would-"

"Molly isn't here right now." Summer said, pressing herself against him. "I am."

Seth swallowed, and Summer pulled his face to hers by the collar of his Lacoste polo shirt. "And besides. Have you ever seen Molly in a Wonder woman costume?"

Seth conjured up that very fond memory, and kissed her. "I've got the room key." He whispered.
