Tony stared numbly, almost blindly at pictures of woman that were shooting down the page on his computer. Normally, this would excite Tony, but, today, he couldn't think or function on anything. He let his chin slip from where he had started to doze as his head landed face first on the computer, producing a loud 'beep' to sound from where he had smacked his forehead on the keyboard. He jolted awake, his chair rolling back into the wall behind him as he groaned, rubbing his head, "I'm awake, boss!" He said, alert, but then realized that no one was in the office at this hour. Even Jenny was asleep.

He stood up and yawned, throwing his coffee cup into the trash as he made his way to the elevator, hoping to go and find something in that 'interrogation' that Gibbs had had with Sarah Taylor. He smacked the button on the elevator, motioning for it to come up to him, and then stepped in as the doors slid open. Tony couldn't remember much as he pressed all the buttons (he couldn't remember what floor the interrogation room was on) and waited for it to go down, poking his head out on each floor it stopped at before it finally stopped at his destination. He sluggishly moved out and fumbled with his keys before opening the door to the observation room, walking over and jabbing the 'eject' button of the previously recorded session. He tapped the tape against his fingers as he slugged back to the elevator, pressing the 'up' button. It opened up to reveal a very informal, very angry looking Jenny Shepard, who was dressed in a gray 'NCIS' sweatshirt and black sweatpants.

"Shit, I'll take the stairs." Tony mumbled as he started to turn around, but Jenny grabbed Tony's shoulder before he could move.

"No, you'll take the elevator." She said, and then barely had to move him as he trudged into the metal lift. She pressed the button, it dinged, and then started to move. She flicked the emergency stop switch, and the elevator lurched as the lights went off. She turned to him, crossing her arms and staring at him, "I thought I told you to go home, Tony."

"I couldn't."

"And why not, DiNozzo? I want an answer."

"I put Ziva through this, Jenny, I have to put myself through the same pain that she went through."

"You don't have to, Tony."

"Oh yeah? And what if it was Gibbs accused of murder, huh, Jen? What if I was director, you were a senior field agent, and your partner, the person you loved, was accused of murder? What if it was you who was the senior field agent and your partner, Leroy Jethro Gibbs was the man that was accused of murder? What if I told you to go home and get some sleep? You wouldn't do it, would you Jen?"

"My personal life is none of your business, DiNozzo. And it's Director Shepard or Ma'am, and that's it." she said, flicking the emergency switch off as the elevator lurched up a floor, opening up to the squad room. Tony walked out, and Jenny stayed on, "Goodnight, Agent DiNozzo."

"Night." He nodded his head, walking back towards his desk. He ran a hand through his hair and plopped down onto his desk, shoving the tape in. After watching it a couple of times, he realized there wasn't anything there. The only thing that had happened had been the fact that Sarah had accused Ziva of murdering her boyfriend. That had been enough evidence for Gibbs to arrest her. But there wasn't enough evidence to prove that Ziva had actually killed the man. But the knife…that was just enough… and Ziva's nervousness around the man…and the fact that she was drunk…Gibbs knew because of him…because he had tried to interrogate her in a place that Gibbs could easily here. And, because of that, because Ziva admitted to stabbing the man, Gibbs had arrested her. Thanks to him. "Ugh!" He yelled, and then randomly grabbed something off of his desk and chucked it across the bullpen. It happened to be a stapler, and it split open as it hit the wall behind Ziva's desk. Tony stopped and realized it had calmed him down a little. He grabbed the twenty-something coffee cups out of the trash can by his desk and chucked them at the TV's, at McGee's desk…at Gibbs desk….anywhere. They clattered to the floor as he realized he was releasing his anger at himself; for screwing over his partner.

"Who are you throwing that at?" He spun around and stared at…well…himself. A hallucination.

"You, because you're a big idiot! Stupid DiNozzo!" Tony yelled, throwing his 'American Pie' coffee mug at the hallucination. It crashed into the wall and broke.

"Missed me," he sang, and Tony fumed, opening up a filing cabinet and throwing file folders at his hallucination. The papers fluttered all over the room, almost like snow in the wind, "Look at you, you're a mess. A big, dumb, mess. You screwed over your partner, you're lucky you still even have a job. I'm lucky I still have a job! Come on, DiNozzo, pull it together."

Tony just chucked a remote at his hallucination, who ducked again, "I can't believe you actually believed that chick."

"Ziva?"

"No, Sarah! Can't you tell she was lying? Ziva taught you how to see if people are lying….tell yourself she's lying. Tell her. Who you gonna believe? Ziva or Sarah…if that is her real name."

Something clicked in his mind as raced over to his computer. His hallucination disappeared, but he didn't seem to notice as he copied the picture found on Sarah Taylor's drivers license and ran a search on it. He impatiently rasped his fingers on the desk as the search finally stopped on a woman with brown hair instead of blond, but the same visage as Sarah Taylor. Except, the woman with brown hair was named 'Amy Sloane', and she was on the FBI's most wanted list, for killing five men. She was a serial killer.

Tony's eyes went wide; the widest that they had gone that night. Gibbs had let her out of custody…a serial killer was on the loose…Tony fumbled with his work phone and finally picked it up, dialing Gibbs' number.

"DiNozzo? Why the hell are you-"

"Boss, you better get in here. Turns out Sarah Taylor is a fake name. Her real name is Amy Sloane, a serial killer."

"On my way. Call McGee, get him in there."

"On it, boss." He said, and then hung up the phone, his heart racing. Ziva didn't kill that marine. 'Sarah' did. He picked up the phone and dialed the number for McGee as well as Ducky. Was it possible that Ziva's stab hadn't been fatal? He needed another look at that autopsy.
