From what Erzsébet had told her, she and Greg had had a very productive talk. There was, however, a problem; Erzsébet still had a fiancé, whom she didn't have definitive proof of was cheating. Once that was established, she could break off the engagement. Sara had learned, from both Greg and Erzsébet, that the man she was engaged to had been decent in high school. However, he had never liked Greg, so if he found out where Erzsébet was, and that Greg was there too, there could be trouble. So it had been arranged that Erzsébet would work swing shift with Catherine, Warrick, and Nick to limit her time with Greg. Now Erzsébet, who had now been in Las Vegas for about two weeks now, had gotten some important evidence in that she wanted to finish, so was working a small bit of overtime and was still there when Greg came in with evidence.

"Weren't you supposed to be gone like three hours ago?"

Erzsébet pointed to a spot on a counter. "Bags there," she said, "Chandra should be back any minute to start processing your stuff." She looked up at Greg, and narrowed her eyes a bit when he snickered. "What's so funny? You've seen me in a lab coat before…"

"Not one that was that big on you," he said, stepping behind her to see what she was doing, "you know, we have an automatic process for that." Greg smirked a little as she waved him off, and then went over and took a sip of a cup with Erzsébet's name on it. "Hey, found my coffee did you?"

Erzsébet smirked. "First place I looked. Everyone's very thankful, especially Nick and Warrick." She went over to a printer near the front of the lab and grabbed a paper before turning her attention back to him. "Gregers, I'll buy you more. I promise."

Greg smiled and stood outside the lab, waiting for Erzsébet to come back from dropping off the results in Catherine's office. Before she did, an unfamiliar guy, with a visitor's pass on, came up to him and asked, "Is Erzsébet Sidle here tonight?"

"She's supposed to be off," Greg responded, "but she's little miss detail and-" he paused, suddenly wanting to know exactly who was asking these questions. No matter what their relationship was with each other, he wouldn't let someone near her she didn't want there. "Who would you be?"

The guy glared a Greg for a moment, but seemed to recognize him all of a sudden; it was the same for Greg, he knew who the guy was when he saw the name on the tag: Matthew Simpson. "I'm the man she's engaged to, and you're who she ran away to see, aren't you?"

"Actually, she ran away because you're a-"

But Greg never got to finish his sentence, because just then, Erzsébet walked up. "Matt?" she questioned, sounding more than a little bit nervous, "What are you doing here?"

"I came to find you, Erz," Matt responded, glaring at Greg for a moment before putting and arm around Erzsébet, "how long have you been doing it?"

"Huh?"

"Cheating on me." There seemed to be a change in Erzsébet's manner as Matt's arm tightened around her waist, but Greg couldn't risk his new promotion for this. "I mean, you run off and I find you here with HIM?"

That was when Greg saw the dangerous change in Erzsébet's face; she'd never looked that mad, and he'd known her over ten years. He watched as she wrenched herself away from Matt, and then Chandra came back so he guided the lab tech into the lab so Matt and Erzsébet could have as much privacy as possible in the hall of the Las Vegas crime lab.

"ME cheating?"

Chandra looked at Greg as Erzsébet's words were said, well, screamed; she knew that there was something going on, but then again, so did everyone else within probably a four-block radius. Sara was on her way back from the scene, and Greg hoped there wouldn't be a smackdown featuring two Sidle women. "That's her fiancé," he said, earning a nod of acceptance from the lab tech that was new to the team, "they've got issues."

"I'll try to get this evidence done before anything else," Chandra replied, trying to ignore the argument going on outside the lab, "but I can't guarantee anything if they stay out there the entire shift."

"Yes you, you little tramp!" Greg looked towards the argument then, letting Chandra start her work. "You heard me, Erzsébet, I called you a tramp! I know you've been in love with him since high school."

"Yeah?"

"YEAH."

"Then, Mister Smart-Ass, did you ALSO happen to know that I was fucking raised by my grandparents?" Before Matt could talk, Erzsébet was on him with something else. "Or, that I know that the lipstick I found on your dirty shirts last month wasn't mine because I would NEVER wear such a god-awful shade of red?"

"Erzsébet, he's HERE. YOU are HERE."

"So is my fucking sister."
