AN: Just an idea that I had...If you don't like it, then don't read it!

"Mr. Lawrence?" Olivia gawked, her eyes widening. She stopped in the doorway of the squadroom when she saw him exit the elevator. Geez, he looked so much older than when Olivia'd had him as a college professor almost thirty years ago. Before she'd gone to the police academy, she'd taken a few extra classes in history and science for some credits; she had figured that it couldn't hurt and it would look good on her resume. She'd quit before she could get all the credits, though, because of Rob Lawrence.

"Olivia Benson! You become one of the best ass-kicking cops in Manhattan and you don't call your favorite old professor?" Rob Lawrence joked, pulling Olivia into a hug.

Olivia laughed nervously over his shoulder. She didn't say so, but she wasn't exactly thrilled to see him. He hadn't been her "favorite old professor" at all. In fact, he'd kind of creeped her out by pulling moves on her from time to time. He had eventually caused Olivia to hate him because of an incident that she couldn't forget, unlike all the others he had put her through.

"Wow...Uh, Mr. Lawrence, if you don't mind my asking, how exactly did you find me?" Olivia asked, trying not to sound as concerned as she was.

"I saw your picture in the paper," he started, pulling out of the hug finally. "Great headlines, by the way! "NYPD Detective Olivia Benson and her partner Elliot Stabler catch the Upper East Side Rapist within two days!" I couldn't believe it! My Olivia Benson?" Rob shouted.

Elliot looked up from his paperwork, his blue eyes flitting over to Rob to see what was going on. Olivia glanced at Elliot and looked back at Rob.

"Yeah...thanks, but it was really my partner who solved it," Olivia said.

Elliot stood up and forced a smile onto his face. He walked over to them and put a hand on Olivia's shoulder. "Right...you said it, she's quite the kick-ass cop," he said. "Don't know what I'd do without her."

Rob smiled. "Hi. I'm Rob Lawrence. I taught Olivia college history."

Elliot shook his hand. "Detective Elliot Stabler."

"Well, nice to meet you, Elliot," Rob murmured. "Olivia, you look so beautiful! You haven't changed too much in...what has it been, nearly thirty years?" he beamed.

Olivia tried her hardest not to look uncomfortable. "Uh, yes, Mr. Lawrence," she said.

"Oh please, babe, call me Rob," he insisted.

Olivia shuddered when she heard herself being called 'babe' by this creep. He wasn't too much older than her-only about six years-even though he'd been her teacher.

"Okay, Rob," Olivia said.

Elliot went to sit back down, but Olivia grabbed his arm. "El, we need to go. We have to make it on time," Olivia said, looking at Elliot, hoping to give him a hint with her eyes that said, "Back me up; this guy's a creep."

Elliot nodded and looked at her for a minute and then glanced over at Rob. "Uh, yeah. We've got to go. We're working on a case right now. It was nice to meet you, Rob," he said.

Rob stared at them for a minute, a freaky grin frozen on his face. Olivia remembered that grin. That grin scared her more than she would ever admit to.

"Yes, yes, nice to meet you, too," he replied, his eyes moving from Elliot to Olivia. "Olivia, you must have dinner with me some time. We could catch up."

Olivia looked away uncomfortably. "No, that's all right. I'm very busy these days."

"Oh, but I insist. Come on, Olivia, I'm paying. Tomorrow night? Seven, maybe? I'll pick you up at your place," he said.

Olivia thought about saying, "You don't know where I live", but then remembered that Rob was just suggesting that she tell him where she lived. No way.

"No, that's really okay. We will most likely still be working this case tomorrow. I'll be busy," she declined again.

"Then Saturday? I've got to get to know my Olivia again," he said. He walked forward and put his hand on Olivia's shoulder.

Olivia couldn't stand it anymore. She knew that every action he made was truly perverted, behind his mask of innocence. She flung his hand off of her shoulder.

"I'm not your Olivia. Never was. Leave, Rob. You're not picking me up tomorrow," she snapped, turning away from him and walking back to her desk.

"When can I pick you up, Olivia? Some time soon?"

"Just leave," Olivia grumbled from her desk.

Rob opened his mouth to say something more, but Elliot grabbed his arm. "Would you like me to show you the way out?"

Rob gave up and left, looking angry. Elliot went back into the squadroom and sat down at his desk across from Olivia. She didn't say anything. She was just shuffling through some papers, a stressed expression on her face. Elliot looked down at some papers too.

Without making eye contact, he asked, "You gonna tell me what that was about?"

"It's not big deal, El."

"Didn't seem that way." They still weren't making eye contact. Elliot was sorting different papers into two files, Olivia was typing up some reports.

"It's nothing."

Elliot, figuring Olivia wouldn't talk about it, dropped the subject. He wondered, though, who Rob was and why he had obviously scared Olivia so badly. He almost never saw that look of fear in Olivia's eyes, but he saw it when she had been speaking with Rob.

Cragen walked out of his office. "You two go home, get some rest," he said. Then he walked back into his office and shut the door.

Olivia stood up, gathered her things, and began to walk out of the precinct, Elliot following. He caught up with her.

"You all right?" he asked.

"Yep," she said, smiling a smile that Elliot knew was fake.

Elliot knew that she was not fine, but he also knew that she wasn't going to tell him anything and he shouldn't push her, so he just let it slide.

"See you tomorrow," he said as they exited and walked their separate ways.

"Bye," she said with a smile that she hoped was reassuring to Elliot.

As he drove home, Elliot wondered why Olivia had been so upset when she'd seen Rob. Had she seen him do something? Even worse, had he done something to her? Something about this Rob Lawrence seemed a little sick. Just the way he had given Olivia that toothy grin, the way he spoke to her in an attempted seductive voice, the way he rubbed her shoulder when Olivia was clearly uncomfortable. Who was he?

AN: So, this was just an idea that popped into my head...please, please, please review and tell me if this story has any worth and if I should continue. It could definitely get some E/O pretty soon if you want it to, so just tell me what you think! :)
