Chapter 2

Dave took the man back to the morgue and Greg and Amanda finished processing the scene.

"You don't seem fine. I don't want to pry, but you looked… like you need to sit down and take a breather." She said.

Greg knew he would have to tell her if she was going to work the case with him, but if his suspicions were right, it also meant that he might be off the case.

"I'll fill you in on the way back to the lab." Greg said. On their drive back, he told Amanda about Ellen Whitebridge, whose real name ended up being Irina Pasternack. As much as he tried, he couldn't keep his personal feelings out of it. He explained her crimes, what happened to her ancestor and her goal in her murders.

"She dated me to get information. She claimed that she really did like me, but… how much of it was just her way of manipulating me?" Greg said. Amanda listened with wide eyes.

"What about the trial, did you have to testify?" She asked.

"No. The crime lab didn't want me to testify for the prosecution because they said I'd had a personal relationship with her. The defense was going to call me to testify on her behalf, but the judge wouldn't allow it because I work exclusively with the crime lab and it would be a conflict of interest. It was a giant nightmare. I never went to the trial at all." Amanda nodded, patting his arm.

"It must have been horrible for you. She must have seemed like such a great person, and to find out she was using you…" Greg smiled. He decided Amanda nice. She didn't fill the silence with chatter and she was good at listening.

"That's the problem, though. Her boyfriend or manager or whoever he was, Roderick Hammerbacher, he died and as far as we knew, he was the only one helping her. She's in prison. So who else could be doing this?" Greg wondered.

"Good question. Let's hope it isn't some kind of copycat who's trying to get attention." Amanda replied.

In autopsy, Doc Robbins confirmed that cause of death was electrocution. He showed Greg and Amanda the burn patterns on his scalp, the burn across his chest, wrists and ankles.

"This looks an awful lot like that case from years ago, but they put that woman away, didn't they?" Doc Robbins asked.

"Yes, they did." Greg said. They collected trace from the body and returned to the lab, where Morgan and Sean were already analyzing evidence from their scene.

"Give the stuff to Hodges, I have to talk to D.B." Greg said to Amanda, who nodded. She smiled sympathetically, touching his arm.

"It's going to be alright. This is going to turn out to be some copy-cat and it won't be a problem." She assured him. "Maybe you won't have to revisit this."

"I hope so." Greg said, even though he had a feeling it wouldn't be.

Morgan watched Greg and Amanda talking from across the room. Amanda liked to put her hand on his arm a lot and she smiled in that quiet way that girls like her had about them. She felt a small twinge of something. She didn't want to call it jealousy, because she had no reason to be jealous of Amanda. It wasn't as though she had any claim over Greg. She didn't even know if he had a girlfriend, but she just assumed he didn't. He never talked about going on dates, but neither did she. Except she didn't talk about it because she wasn't going on any.

But still. She was usually paired with Greg on cases and when people started calling him 'boyfriend' Greg to her face, she panicked a little and tried to pair up with other people. She didn't want her dad coming around, asking about what people meant by 'boyfriend' Greg. It wasn't even that she wasn't interested in him, because she did like him. He was very handsome, and smart, and funny… and basically her best friend, but she knew that if anything were to happen between them, it would break up the team and she didn't want to be the person that did that. Especially considering everything they'd been through recently.

Even so, she missed working with him. They had a good rhythm going when they worked together and she liked how she could just be around him and not have to worry about what she said or how he would react. Sometimes, she would obsess over things she thought were amazing, and Greg didn't make fun of her for it. He thought it was amazing, too! Sean might be cute, but she always felt as though she had to put up some kind of invisible barrier between the two of them when they worked together. She couldn't just say what came to her mind because Sean was the type of guy that would have made fun of her for saying something about Bloody Mary popping out of a mirror at a crime scene and stabbing a woman to death. With Greg…. He'd just gone with it.

Why am I so stupid, why did I volunteer to work with him? She wondered.

"I can't believe it was a suicide, I was sure it would be an interesting case." Sean said. Morgan resisted the urge to roll her eyes. He sure did whine a lot.

"Let's go see if Greg and Amanda need any help, then." Morgan said. Sean reluctantly followed her as they walked over to Amanda.

"Do you two need any help?" Morgan asked. Amanda shrugged.

"Greg went to go talk to D.B. about our case, apparently it matches the M.O. of someone who's been in prison since 2011." Sean perked up at this.

"Really? Now that sounds interesting."

"Oh, wow. I wasn't even here yet in 2011. I guess we can go ask Sara about it." Morgan said. The three of them found her with Henry in the DNA lab.

"You aren't finished already." Sara said, staring at the three of them.

"Greg is talking to D.B. about the guy they found. It matches the M.O. of someone already in prison for the crime." Amanda said. "None of us were here when the case came through the lab, so we thought we would ask you about it."

"Sure thing, what's the M.O.?"

"The man was electrocuted, he had burn marks on his chest, ankles and wrists." Amanda said. Sara's eyes went wide.

"What is it?" Sean wondered.

"Greg… explained it to me, but he seemed reluctant to share details." Amanda admitted.

"Why?" Morgan and Sean asked at the same time. Sara pulled them all out of the DNA lab and toward the break room.

"Greg was personally involved with the case. We may have to interview her again and it would be really awkward for him. I know he'd want to be there, but… I guess that's up to D.B. He wasn't the supervisor when we got the case, Catherine was." Sara said.

"Personally involved?" Morgan asked.

"Yes. This woman came on a tour through the lab. She flirted with Greg and he asked her out. They went on a bunch of dates and it all happened really fast. He really fell for her hard." Sara said.

"Her who?" Sean wondered.

"She said her name was Ellen Whitebridge, that she was a fourth grade science teacher. She seemed like such a sweet woman. Nick encouraged it, but she wasn't who she said she was. She stole some other woman's identity and she lied about her job." Sara explained.

"What does that have to do with the case?" Sean demanded.

"Well, she was dating him to get information. She was our killer." Sara said with a frown at Sean.

Morgan's mouth fell open. "What?"

"Greg dated a serial killer." Sara said. "And now he's going to talk to her for the first time since she went to prison for it."

D.B. not only wanted to keep Greg on the case, he wanted Greg to be the one to question her. He insisted that having Greg be to one to question her might provide 'unique insights' into the thought processes of a female serial killer.

"Amanda isn't ready for an interrogation like this, I want you to take Sara or Morgan with you, because they're more experienced. Amanda can wait in the observation room." When Greg came back from D.B.'s office, he found Amanda, Sara, Morgan and Sean in the break room. Sean and Morgan stared at him.

"What's going on?" He asked.

"I explained the situation about Ellen Whitebridge, aka Irina Pasternack." Sara said. Greg knew it was all part of the case; it had to be discussed, but he hated the look of horror in Morgan's eyes.

"D.B. wants me to be in the interview room. He wants me to take you or Morgan with me." Greg said to Sara.

"What about us?" Sean asked, pointing at himself and Amanda.

"Observation only. Irina is a master manipulator. She will do anything to twist you up and get you to feel sorry for her. She tried to kill me, I would have been her fourth victim if I hadn't realized what she was really doing in time." Greg said. The CSIs all looked at each other.

"I'll go in there with you." Morgan said. Sure she was nervous, but she wasn't going to stop volunteering for cases Greg worked on because of workplace rumors about romance. If she was a true friend, she'd be there for him, no matter what the circumstances. Even if his ex was a serial killer.
