Seth felt completely despondent. He was indifferent to the emotions swirling around him. It had been two hours since their fight. And the pain that he had felt since then had made him numb.

He felt dazed. Or stoned, or something. He was aware of only two things. Where Summer was and how horrible she looked. She was sitting in a chair next to Anna, saying something to Anna, who was listening and shooting glances at Seth.

Summer looked dead. Her usually tan skin was pale and she was wringing her hands together. She looked a little hysterical, like she might be about to have some kind of breakdown. She was obviously feeling everything Seth couldn't.

And he didn't know why he couldn't feel. But he felt frozen. He was standing in the middle of his own party, watching Summer. She looked up and met his eyes. Her huge brown eyes instantly filled with tears, and Seth felt a wave of horror and guilt, but he didn't know how to express it.

Tears spilled down her pale, hollow looking cheeks, and when she brushed them away, Seth could see that her hands were shaking.

He couldn't stand seeing her like this, knowing he made her that way.

He turned on his heel and went into the pool house. Ryan, who had been watching the scene with Marissa, sent her to join Anna and Summer and followed Seth. Inside the pool house, he found his best friend, sitting in a chair, staring at the ceiling.

"I fucked up, didn't I?" Seth asked.

Ryan nodded. "I've never seen her like that." He thought about it. "Actually I've never seen anyone like that."

Seth looked Ryan in the eye. He wanted to work through this pain, but he couldn't get himself to acknowledge it. "I did that to her Ryan." He said hoarsely. "She's a mess. She's pale and she's still shaking, and crying and her eyes aren't sparkling and I did that to her."

"Yea, well she loves you."

"She did."

"Seth." Ryan said, a little exasperated. "When are you going to realize that she loves you? She will always love you." His tone softened. "How are you holding up?"

Seth didn't know how to answer the question. "I don't know. I feel so lifeless. I know that I'm hurting, but I'm numb to it." He went back to staring at the ceiling.

Summer was the complete opposite. She had been refusing to give Anna any of the details of the fight, but when she locked eyes with Seth, then promptly started bawling, Anna insisted.

She knew from Summer's appearance that something was incredibly wrong. "I went to talk to him, and we started fighting, only it got so intense. I slapped him in the face, and…" She trialed off.

Anna was torn between not wanting to know, and needing to help Summer. "And what?"

"And he hit me." She said, fresh tears slipping down her cheeks.

Anna's eyebrows hit the ceiling. "Seth hit you?" She asked.

Summer nodded. "And then we had sex. Really angry, good sex." She shivered a little bit at the memory. "It was sort of scary…" she let her voice stop.

Anna sighed. "Summer, how long have guys been having sex?"

"Since I got back?"

"Why are you doing this to yourself?"

"I love him."

Anna looked her. She looked awful. Gone was the radiant, confident Summer Roberts, and in her place was a scared girl.

Marissa took one look at Summer, sat down with her and Anna, grabbed her shaking hands, then wrapped her arms around her best friend. Then she got up and beelined for the pool house.

"Seth Cohen, what the hell were you thinking?" she expolded once she got inside.

"Marissa…" Ryan said in a warning tone.

"No!" she cried. "Don't Marissa me. You're an asshole, you know that Cohen? Not only do you have no right to treat her the way you've been treating her, but you really crossed a line when you hit her!"

Seth winced. Marissa continued. "I really don't know what the hell your problem is. Everything you've ever wanted is sitting 25 feet away from you, and you're in here, staring at the fucking ceiling, like this is so hard on you, and pretending you want to marry that snobby bitch."

Seth opened his mouth to defend himself, but Marissa cut him off. "So she left. It was a shitty thing to do. She fucked up. But it's not like you haven't. And now she's back, and she's sorry and she loves you, and you told her you didn't love her? That you loved Molly? Not only are you a liar, you really need to grow up and get over yourself." With that, she turned to stalk out of the pool house.

"Marissa, wait." Seth said. She wasn't going to wait. She really wasn't. But something in his voice made her turn around. She looked at the anguish on his face, and it looked like the floodgates mighbt be loosening up.

Her voice softened. "What?"

"What do I do now?" he asked in a very quiet voice.

She looked aat him sadly. "I don't know Seth. You seem to have this black and white picture of what the right thing is. But it is really right to marry this girl and let her think you love her? You're living a lie if you do and you're going to miserable."

"I can't just not marry her."

"You can't marry her if you don't love her. That's like my mom and Caleb. Or if I went and married Luke. Look, Seth. Ryan and I can't make this choice for you. Your parents can't make it for you. You have to do what you think is best." She turned and started to walk out the door again.

"Marissa?" Seth said, halting her for the second time, "I'm sorry."

She turned around and smiled sadly. "I'm not the one who needs to hear that."
