I guess I'm invisible. Some guy at the coffee shop just bumped right into me today. He didn't apologize or even mention the fact that the force of his body hitting me nearly pushed me into one of the coffee displays. He just kept walking as though nothing had happened. I wouldn't have been so annoyed if it weren't for the fact that a guy had been holding the door open for a stream of people and, as soon as I got there, let it go to slam in my face. I know people seem to think invisibility would be a great super power, but it actually kind of sucks. Besides, I know I'd never be able to use it to my advantage because with my luck, as soon as I went to intentionally use it for whatever I needed it would disappear, only to reappear when I didn't want it.

Tim stifled back a yawn and rubbed his eyes with his knuckles. The lab vacant, save for him, and it was eerily silent, with only the soft hum of the computer breaking the silence. He wasn't sure what time it was, nor was he sure just how long he'd been down here. He was nearing the beginning of Anna's blog and would soon be out of entries to read. He thought about going home and finishing them off tomorrow, but he knew that even if he did go home, there was no way he would be able to sleep. As long as he was awake, he may as well be working to find Anna. He clicked on the next entry.

I had a crazy dream last night. Actually, I guess it was more of a nightmare than anything else, considering the subject matter. I know most of you know about it, though I guess a couple of you didn't meet me until after the Jerry incident. Jerry was this guy I kind of dated in high school. I wasn't that into him, but he was into me and I kind of figured he may be as good as it gets, so I was with him for a while.

Then, though, he began to get really possessive, not to mention stalkerish. He'd drive by my house just to make sure there were no other guys there or call to see if another guy answered. It got really ridiculous, so I finally just broke it off with him, but he didn't stop. He'd follow me around and park outside my house to see if I was with anyone. Funny, right? I mean, I finally meet a guy who really likes me and he's some psycho stalker. Such is my life, I guess. Anyway, it got to the point where I had to talk to him. I approached him after school one day – he was in community college by this point, but he always scheduled his classes so that he'd be in the school parking lot by the time school let out for me –and I told him that I was going to call the cops if he didn't leave me alone. He got pissed! He grabbed my arm and tried to keep me from leaving and started yelling at me. If it hadn't been for the fact that the basketball coach was in the parking lot…well, I won't even go there.

He started crying, telling me he was sorry and that he was just trying to make things right between us. I felt sorry for him, so I decided not to press charges. After that, he never tried to contact me again and I eventually forgot about him.

Last night, though, I dreamt that I was back in high school and still with him. He kept trying to pull me away from home and no matter what I did I couldn't get away and I couldn't get anyone to help me. I woke up almost crying and it took me a second to realize it had just been a nightmare. Still, it really freaked me out and I had to go out and double check that all of the doors and windows were locked. I haven't discussed him with anyone who didn't already know him – not Shannon or anyone in my unit – because I figured if I didn't talk about him I could just pretend like it had never happened. But that dream…it just brought back things I'd prefer to have kept locked up in my mind.

As Tim read through the entry, he became more and more alarmed. When they'd gone through Anna's file and personal history, they'd found no mention of any stalker by the name of Jerry. Her parents were both deceased and she had grown up in Iowa, so anyone who probably knew about the incident hadn't been contacted by the team. Was it possible that this guy from her past had shouldered his way back into her life?

Whether or not it was possible, Tim knew he had to let Gibbs know he may have gotten a lead in the case. No longer fatigued, Tim pulled his cell phone out.

"She never mentioned anyone named Jerry," Shannon told Tony and McGee as they sat on the small couch. After Tim had called Gibbs the previous night, the team had assembled and now, with a second wind, were running down the lead. Ziva was finding everything she could about Jerry Lester and Tony and Tim had gone back to talk with Shannon about him. "She didn't talk much about her childhood, though."

"Had she seemed particularly jumpy lately?" Tim asked.

Shannon was pensive for a moment before nodding. "It was only one day about a week ago. She got home and she looked kind of…I dunno…freaked out, I guess. When I asked what was wrong she just shook her head and told me something about not looking where she was going and almost being hit by a car."

"Why didn't you mention this before?"

She lowered her eyes sheepishly. "I hadn't really thought much of it, Agent DiNozzo. It wouldn't be the first time Anna didn't watch where she was going.' She looked up at them, eyes wide. "God, that sounds so harsh of me to say…I just meant she could be kind of clumsy sometimes and sometimes she would get lost in her thoughts and just tune everything else out. She wasn't always aware of her surroundings."

Tony's cell rang. He pulled it out, gestured to McGee to continue with the interview, and stepped out into the hallway. McGee looked back to Shannon. She was almost the exact opposite of Anna, with long, blonde hair and bright blue eyes. She was petite with a slim body and nothing looked to be out of place. She looked like the kind of woman you'd expect to see on a cheerleading squad, not in the Navy. From the pictures he'd seen of her around the apartment, she had no trouble socializing with others or with getting dates. "How did you and Anna end up as roommates?"

"We're next to each other alphabetically, so we ended up beside each other throughout training. We just ended up talking a lot and becoming friends. While women are becoming more interested in military, we're still far outnumbered by the men. It's nice to have a girlfriend to go to when none of the guys would understand."

"What kind of girl is she?" he asked, specifically saying "is" rather than "was."

"She's nice, Agent McGee. She's a bit awkward and she spends more time talking to people online than in real life, but she's not anti-social. People kind of wrote her off as being anti-social, but she was just shy…is shy. She told me she likes talking to people online because you don't have to actually face them and you can take all the time you need to respond to them. It takes the pressure off. I didn't think that was completely healthy, but I'm glad she's able to socialize, even if just over the internet."

"I take it she didn't date much?"

"No," Shannon said with a shake of her head. "I tried to set her up with some guys I knew, but it never quite worked out for her. I felt bad for her, though I never told her. I mean, who wants to be pitied? Still, she really does have a lot to offer a guy."

Tony re-entered, ceasing Tim's pointless questions. He already knew the answer to so many of them and they most likely had no bearing on her disappearance. Tim just wanted to know more about her, like a love sick teenager. "Come on," Tony beckoned to Tim. They bade Shannon good-bye and exited the apartment before Tony filled Tim in. "Ziva was talking to one of P.O. Quigley's old friends back in Iowa. She claimed that Quigley had recently run in to Jerry."

"He threaten her?" Tim asked.

"According to the friend, Quigley claims he looked just as surprised to see her as she did to see him and that they'd talked for a bit, but she had still been a bit spooked about seeing him."

"Is that all we know about the guy?"

"No, we also know that he dropped out of the community college he was attending to work for his uncle's roofing business. After three years of that, he just up and left. He paid the bills by doing odd jobs around towns and made his way east to Virginia. As of late, he's been doing some work installing air conditioners and cleaning gutters."

"Address?"

"None listed. According to his employers, he sleeps on couches of friends. Sometimes they let him crash in one of the offices."

"Where is he now?" Tim asked as they approached the car.

"That's just it, McGee," Tony replied, sliding into the driver's seat. "He hasn't been seen in about a week. Seems he disappeared right around the time our Petty Officer did." They squealed out of the parking lot, their current suspect growing more and more suspicious. Tim was becoming more and more frantic, certain that he had to find Anna before it was too late.
