Author's Note: First and foremost, I would like to thank everyone who favourited, followed or reviewed this story! I didn't think I would get quite the response from the last chapter! Secondly, I would like to apologise for the brevity of this chapter... thought I would build a bit more tension into the story! :) As if it needs any more, yes? Also, I recently noticed an error in Patricia O'Neil's name... I can't believe I made that error after the fact that I have all the original characters' names written down in my notes for this story! For that, I apologise again. So without further ado... here is the chapter!

Back at the station Chloe looked on through the one-way mirror as Dov tried to interrogate Gregory Schlenz. The man had refused to speak and even refused a cup of water even though he had been in the interrogation room for over two hours. "Look, I know my rights officer," Gregory spat as he stared at Dov. "I don't have to say a word to you. If I do it can be held against me."

Dov nodded his head. "Yes, that is part of your Miranda Rights, Mr. Schlenz. I told you them when we arrested you. Look, I don't know why you ran from us when all we were trying to do was ask you a few more questions. You do know what that means, right?" Epstein drawled as he stared at the man.

"I know what it means," the man said as he rolled his eyes. "And I know what this means too." He pointed to the cup. "You want to take my DNA without my consent and knowledge. I wanna call my lawyer."

"Fair enough. I'll get the phone." The officer stood up and took the cup of water with him. He paused halfway to the door and put the cup to his lips and downed the contents of the cup. "Ah... I needed that. Thanks for the water, Gregory!"

The man in the chair seethed as he watched Dov walk out the door. Chloe suppressed a giggle as the door swung open to her room. "Well, what did you think?" Epstein asked as he stared through the one-way mirror.

"I think that water bit was horrible," Price said with a smile.

He smirked as he nodded his head towards Schlenz. "I think he is hiding something. From what we know, Mrs. O'Neil knew his wife was around... why else would she ask her to watch over her house while she was away? Also, he ran when we told him that her car was parked in O'Neil's yard. It is just strange I tell you."

"I agree with you, Dov," Chloe stated as she turned to look at her boyfriend. "So who do you think he will actually call when we give him the phone?"
He shrugged his shoulders. "Who knows? Maybe his lawyer... maybe his mistress. With some of these people we bring in, I can never tell. Keep an eye on him, I am going to get a phone."

As Dov started to walk towards the door, it burst open revealing a slightly dishevelled Nick. "There you guys are!" He said as he closed the door behind him. "I have been looking for you all over the station."

"Did you check with booking at all when you got in?" Dov questioned as he stared at his friend.

Collins shook his head. "I came through the front and searched the whole place for you." He frowned when he realised the logic behind what he did. "Maybe I should have spoke with booking or anyone else actually. I bet a lot of people think I am actually crazy now, especially how I ran through the place looking for you."

Dov took a step back while eyeing Collins warily. "You ran through the whole place without thinking how everyone would react? Jeez, you really must be worried about everything that is going on."

Collins shook his head. "Traci called me before I came back to the station. She said things are a bit more complicated than we actually thought and with Mrs. O'Neil skipping out, she might be right."

"Wait..." Chloe stated as she stared at Collins. "Mrs. O'Neil left the hotel? Why would she do something like that?"

The ex-military man shrugged his shoulders. "I don't know, but I have a weird feeling about this whole thing." He held up the evidence bag containing the phone that he picked out of the hotel trash bin. "The guy at the front desk at the hotel said Patricia O'Neil used this to call the cab that picked her up. Traci asked me to bring it to you, Dov. She said you might know someone who could maybe get something out of it, but she is certain it might be a dead end."

Epstein grabbed the bag from Collins and inspected the phone inside. "Hmm, it's your basic flip phone. Maybe we can get something off of its records, but not sure if Traci thinks it's a burner. Let's take it to the lab first before trying anything else with it."

"Why the lab?" Collins asked as he watched the other man step into the hall.

"Might have other prints on it besides hers," Dov replied over his shoulder. "If she pulled a runner, there might be someone else in on this too. Shit..." He paused right outside the interrogation room that Gregory was in. "Hey... Collins!"

"Yeah?"

"You wanna get a phone for this guy in here?" Epstein asked as he pointed towards the closed door. "He wants to speak with his lawyer, but if this is as important as you say, then I am going to be awhile. And who knows... maybe your interrogation skills are better than mine." Dov continued walking down the hall and turned the corner towards the evidence room.

Chloe smiled at Nick when he turned towards her. "It's worth a try. You know how Dov is..." She walked toward the door and stopped as she reached for the handle. "I'll go get the phone, try talking to him for a bit... you may be able to loosen him up some."

Gail looked up at Holly as the pathologist stood on her leg again to reach the vent. With a piece of paper in her gloved hand, the doctor tried her unspoken theory. "Shit..." she muttered as the paper stuck to the vent. She grabbed the paper from the vent and stared down at Gail. The blonde officer could hear the fear in her voice when she said. "Help me back down." Gail steadied herself as she reached her uninjured hand up for her girlfriend to grab a hold of.

"Holly, you are going to have to tell me sooner or later what is going on inside that head of yours," the officer said once she raised herself up from a kneeling position.

"I..." Holly started as she looked into Gail's eyes but quickly turned away when another idea flickered in her brain. "Give me a moment, honey." The pathologist knelt down on the floor in front of the door. She moved her body as close to the door as she could and waited for a few seconds before she stood back up. Her eyes were riddled with panic when she looked back at Gail. "I think you should sit down for this."

Gail huffed, but complied as she walked across the floor to sit on the tabletop. "Look, whatever it is, I can handle it Holly. I'm a cop. We handle tough situations all the time. Hell, I was kidnapped before! I've been quarantined, and shot at. So whatever it is you have to tell me, go ahead."
"You're right." Holly replied with a sigh. She stood in front of her girlfriend for a few moments before she started pacing the length of the room. "I should have told you my thoughts before I decided to test the theory..."

"What was it that I said that made you run around like a hamster on coffee?" Gail asked playfully when she noticed that her girlfriend's voice was quavering under the mask. "Also..." she raised her hands in front of her. "Why do I have to wear two pairs of gloves?"

Holly adjusted her glasses with her gloved hand then crossed her arms in front of her. "A thought... a really scary thought crossed my mind when you mentioned something about the temperature of this room. It is stifling yet arid. It reminded me of a few of the rooms that I had visited at the medical lab while taking a few courses in virology."

Gail stared at Holly. "When you say virology... you mean..."

"The study of viruses, yes," Holly said as she continued to pace the floor, being mindful of the bloodstains near the doorway. "So when that thought crossed my mind, I had to react in the only possible way. I had to protect us just in case it was true. Then I needed to test the theory after we took the necessary precautions."

"And the conclusion to your theory?" Gail queried as she felt a tightness settle in her chest.

"This is a negative pressure room. The vent..." Holly pointed to the vent over the door. "Is withdrawing the air from this room, while a steady stream is flowing through the bottom of the door."

"If there is an opening big enough for air to stream through, then why can't they hear us when we called out to them before?" The officer questioned as she tried to sort out everything that the pathologist was trying to tell her.

Holly shook her head. "I think the air is being feed through from another vent directly under the door, so it is still airtight in a sense. The air was warm yet stale as if it is be manufactured specifically for this room."
"Oh..." Gail said as dread started to wrap around her. "So... what does it mean if this room has negative pressure?"

"It could mean several things." Holly said as she wrung her gloved hands together. "In some rooms... like in a museum, it keeps important and ancient pieces of art from deteriorating because it keeps the pollutants that riddle our modern atmosphere from entering the room. In a hospital, it keeps patients, who are staying within the hospital for certain periods of time, from being exposed to other pathogens that another patient may have, which cuts down on patients getting sick while in the hospital."
"And in the situation you described with viruses?" Peck asked though she did not wish to hear the answer.

"The negative pressure creates a bio-containment room," Holly stated in a hollow voice. "It keeps a virus from infecting the rest of the labs. They normally use it for the higher level labs."

"And what sort of viruses would be housed in those labs?"

"The sort of viruses you don't want to escape."
