"That's the last of it." The delivery man said, closing the door of the moving van.

"Thanks." I replied, carrying the last of the boxes into my new house.

I wasn't sure how long we'd be living here undercover. They were currently tracking the whereabouts of Nazir and his circle, so I guess until this guy was caught or dead, we'd be here in this little town in Pennsylvania.

Rosewood. It was a small, quiet community, like you would see on TV; kids running around the neighborhood, teenage girls meeting for coffee at the local café, parents working in big companies and law firms, even the occasional housewife gossiping with her friends on the front porch. It was all a little too quiet. But I couldn't worry about that right now. My target was Emily Fields.

'I wonder what she's going to be like. Is she preppy? I don't think I could handle that. Maybe she's a jock. That would be easier. I guess I could join a sports team to make myself seem more like a high schooler. Or maybe a club. The debate team would love someone like me. Maybe even..'

"Spencer!" I was pulled out of my thoughts.

"What?" I asked, only semi-annoyed.

"Family meeting. Now." Mona said from outside my room.

I rolled my eyes. "Be right down."

I walked down stairs to find Mona and my "parents" sitting on the couch. I sunk into the nearest chair.

"So what now?" I asked. "What's our story?"

"Well, our family just moved here from Albuquerque, I'm your mother, Veronica Hastings, and this is your father, Peter. Mona is your cousin who is staying with us while her father is over-seas."

"Wait, Hastings is my last name. Like, my real last name. Why aren't we using a cover name?" I questioned.

"Well, you two have been on many undercover missions before, so you've never used your real names. We wiped your files from the system, so it looks like you two are completely ordinary teenage girls. Plus, if anyone does find out that you are working for the CIA, then they will assume your real name is your cover name. So, you will go by Spencer Hastings and Mona Vanderwaal." Peter informed.

"Okay, well, this will be new. What else? What will you two be doing?" Mona asked our new guardians.

"Peter and I are both lawyers working for the District Attorney's office." Veronica said. It was hard to think of her as mother. "And you two will start at Rosewood High School as seniors tomorrow morning."

"Hooray." I replied unenthusiastically. "So how is this whole surveillance thing going to work?"

"We have set up a nerve center in the barn out back. While one of us is working, the other will be here monitoring Mrs. Fields. You two have been scheduled to have almost every class with Emily, and for those you don't have with her, you'll always be nearby. You two need to do everything you can to get into her circle of friends. Even if that means making friends with someone else to get close to her, do it. But don't seem too eager. We don't need her getting suspicious. Apparently she's a pretty bright kid, and her grades are pretty good, too. But she missed some school after her father died, so she may need help catching up. I'm sure that won't be a problem for the two of you."

I looked over at Mona who just smiled at me. I nodded, returning her smile. "Okay then. Well, I'm going to go unpack." I stood, approaching the stairs. I heard Veronica call out as I began ascending.

"Dinner will be ready at seven." I chuckled.

"Thanks, mom." I replied, hearing the laughter from behind me.

I was in my new bedroom, stacking books on the shelf when I heard a knock on the door behind me. I turned to see Mona standing there, hair and make-up done, wearing an outfit that made her look like a model.

"Well damn. Where are you going, the club?" I asked with a chuckle.

"No, I'm just trying out a new look. I was thinking, if we are really getting a chance to relive senior year, I'm not spending it as Loser Mona again. So, say hello to Hot Mona." She twirled around, giggling.

I smiled. "Well, this is a nice change from all the black you normally wear."

She scoffed. "You are no different Spence. You dress like a senator most of the time."

"Well, sorry I wanted to look professional for my important government job." I retorted.

"Now is the time to reinvent yourself. Be who you wanted to be in high school. Change it up. But please, don't come to school wearing a pinstriped pantsuit, because I will refer to you as Madam President."

I laughed. "You're right. But try not to have all the boys chasing after you."

"Oh, I promise I'll have all the boys and most of the girls wanting to get underneath my skirt." She replied with a wink as she exited my room.

I shook my head. "Good luck with that," I called out after her. If I knew one thing for sure, it was that this whole high school experience was going to inflate Mona's ego even more.

There was a knock on the front door. I heard Veronica call from downstairs.

"Spencer, can you get that?"

"Sure thing, mom." I shouted back, laughing to myself.

I hopped down the stairs and opened the front door. There, to my surprise, was our target.

"Hi, I hope I'm not interrupting. My name is Emily Fields. My mom asked me to bring this over." She handed me a basket with some wine and expensive looking jams.

"Thanks. I'm Spencer Hastings. Nice to meet you." I extended my hand towards her.

She looked down at my hand questioningly, but took it anyways, shaking it firmly. I guess a hand shake isn't something teenage girls do when they first meet.

"Um, would you like to come in? I'm sure my mom wants to thank you for the basket." I asked.

She looked hesitant at first, but she just smiled, and nodded. "Sure."

I closed the door behind her, and then made my way into the kitchen.

"Hey mom, this is Emily. She brought presents." I announced, placing the basket on the island.

Veronica turned around from the stove, a big grin on her face, probably because Emily has just offered herself up on a silver platter. This makes our job a lot easier.

"Honey, go get your father and Mona." She instructed.

I left the room and walked into Peter's study. I knocked on the door, looking in as he looked up from his desk.

"Guess who's here?" He looked confused at first, but then seemed to figure out who would be here that he would be interested in.

"I'll be right out."

I shut the door and went over to the staircase, deciding to do something very teenager-like.

"Mona, get down here!" I shouted up the stairs.

She came bolting down, worried.

"What?!" She asked, looking panicked.

"We have company." I said, giving her my most innocent smile.

She scowled at me, and I just laughed, walking back into the kitchen. Spies are always so jumpy.

At this point, Peter was greeting Emily, who looked completely comfortable on the outside, but years of studying people made me notice how overwhelmed she was. I smiled to myself as I studied her. She dressed casually, but not so casually that she didn't put any effort into her outfit. She wore a pair of faded skinny jeans and a t-shirt, and matched it with some sneakers and a leather jacket. Even through the layers of clothing, I could tell that her body was toned. I glanced away from her, realizing that it probably looked like I was checking her out. 'Was I?' I didn't have time to think of an answer as a high pitched voice assaulted my ears.

"Hi, my name is Mona. It's so nice to meet someone! You know, you're the first person we've met since we got here. Anyways, it's so nice to meet you. I hope we can be great friends."

I raised an eyebrow at Veronica, who just chuckled to herself. What the hell was that? If this is the new Mona, I was going to kill her by the time this mission was over.

"Anyways," Veronica cut in, "Emily, would you like to stay for dinner?"

"I would love to, but I have to get home. I have a ton of homework." She answered.

"That's okay dear, maybe another time. Bring your mother next time. I want to thank her for the lovely welcome gift."

Emily smiled, nodding.

"Here, I'll walk you out." I cut in. Emily shot me a thankful look, saying her good-byes to everyone.

I exited the house behind Emily, zipping up my jacket as the chilly autumn air hit me.

"Let me walk you home." I offered. She just smiled and nodded.

We began our walk in silence as I took in the scenery of the neighborhood.

"So where are you from?" Emily asked, giving me an encouraging smile. I could tell she was trying to make me comfortable.

"Albuquerque. It's not cold there like it is here." Which was true.

"Well at least Rosewood won't be as hot as New Mexico in the summer." She offered.

I smirked. "True. So what do you do for entertainment around here?"

She smiled again; she did that a lot. "Well, there's the local café, The Brew, then there's the Apple Rose Grill, which is like the local diner, and there's a movie theater that plays a lot of old black and white movie. Other than that, not much. Most people go into Philly if they're looking for something to do."

"What about at school?"

"Well, there are a ton of sports teams and academic clubs. I'm on the swim team. I'm hoping to get a scholarship to Danby."

"Are you good?" I asked with a smirk.

"Well, I'm the anchor and I hold the fastest record ever recorded at Rosewood, so I think it's safe to say yes." She chuckled. "What about you? What did you do at your old school?"

I guess I'll just go with what I did when I was in high school.

"I used to play field hockey and tennis, and I was captain of the debate team."

"Oh, so you've got the brains and the bronze." She replied, smirking.

"I guess you could say that."

Emily suddenly came to a halt. I turned to look at her.

"This is my house. Want to come inside and meet my mom?"

"Maybe some other time. I need to get home and finish unpacking. But I'll see you tomorrow." I replied.

There was a flicker of disappointment in her eyes, but she quickly offered me a smile.

"Yeah, I'll see you tomorrow. Maybe we'll have some classes together."

I laughed on the inside. "Yeah, maybe." I smiled back at her.

"Okay, well…bye." She waved awkwardly, entering the house and closing the door behind her.

I chuckled to myself. 'She's adorable. Why would anyone want to hurt her?' I quickly shook the thought from my head. 'No, I can't get emotionally attached. This is a mission. And as soon as this guy is caught, I am out of here and back to Washington.' But still, I had this nagging feeling that this was going to be a more difficult mission that we anticipated. I could feel the trouble brewing, and we had been here less than 24 hours.

As I walked the two blocks back to my temporary house, I scanned the surrounding area, looking for points of entry that would need to be monitored more heavily. And I thought.

I thought about the mission.

I thought about the video of the Lt. Col. being executed.

I thought about the men making threats against his family.

But most of all, I thought about Emily's warm smile, and the way it made me feel.

Oh no.
