My name is Sierra Lee Ann Connor; daughter of The Resistance Leader; John Connor.

My missions To help find and protect the survivors of Judgement Day. The beginning of the war between man and machine.

We have fought long and hard. Saw our loved ones die, and almost died ourselves. We have never gave up in what we believed in, and that was freedom.

It was definitely exhausting to say the least., all the fear and anger we felt towards Skynet and the machines was definitely taking it's toll on everyone; including me.

My mind was always reeling, it was always bringing up questions that I of course couldn't answer. Questions like:

What would it be like to not live in fear that the next day might very well be your last? Or, would we win the war or would we lose? Knowing that my father was the leader of the human resistance made our survival more than likely. I know with him we would win...but in the back of my mind stayed that question.

I may be only sixteen; but I have come across plenty of machines in the past. I was taught to be ruthless with them. I've learned to hate them, loathe them with an unimaginable passion. That was until my dad decided to capture and reprogram a T-600 to become my guardian.

I was more then upset I was absolutely livid. I couldn't believe he would do that. Just one freaking glitch in the machines system might just cost me my life, and that's what made me worry.

~XXXxxxXXX~

I was sitting at my stainless steel L shaped desk, doing something or other on my laptop when I heard a knock on the door.

"Come in!" I yelled as my attention went from the sliding door back to my laptop once more. I was listening to music so when I turned back around I saw that it was my father; whom was now leaning against the poster covered wall, smirking like the chesire cat.

"Yeah?" I asked cautiously. I knew that smirk...and it wasn't necessarily good. For me it wasn't anyways. "What is it now, dad?"

He sighed and walked over to me, kneeling in front of me. "Sierra, I need to show you something. Come with me."

He stood back up and offered his hand out to me. I looked back at my laptop and saved what I was working on. Sighing I took my father's outstretched hand, I stood up from my nice, comfy computer chair.

"What is it?" I asked as we headed out of my room and down the hall towards the debriefing room/ experimental room. I hated that room, but I never complained.

He gave me a very goofy looking smile.

"Well you know that T-600 that we captured and reprogrammed right?"

I looked at him cautiously. "Yeah...what about it?"

"Well..." We walked into the room, and I mentally cringed as I saw the machine up and about looking at all the different guns and other weapons that were lined on the wall. This made me feel slightly uncomfortable. I turned my attention fully to my father, only casting the Terminator a sideway glances once in a while.

"What I was thinking Sisi--" I held up my hand to interrupt him.

"Don't call me that."

He sighed. "I know you're not a little girl anymore, though you're mother and I think that you still are."

I rolled my eyes. "Think what you want..."I muttered mostly to myself. Unfortunately my father heard me.

"Don't give me that sort of attitude young lady."

I bit my tongue and waved my hand to let him continue. He sighed with frustration. "If you stop cutting me off I might."

"Alright...I'm sorry dad...continue."

He took a quick glance at the machine who was now staring intently at us, under it's intense gaze I felt like a small ant. I gulped loudly. My father placed his hands lovingly on my shoulder. "Sierra, we reprogrammed the machine to follow YOUR command, because it is to be your guardian."

I swear I thought my hearing was deceiving me. "What?"

He gestured for the machine to come over, and I tensed up. I didn't want it near me. "T-600 what is your mission?"

It looked at me. It's glowing red eyes, making me get chills all the way down my spine. "To protect and follow the commands of Sierra Lee Ann Connor."

I grabbed my fathers arm tightly and turned my head towards the Terminator. "Excuse us for a moment."

It only nodded and watched us walk towards the farthest corner. "What the hell do you think you're doing?!" I asked angrily.

If he seemed angry with me swearing or seeming ungrateful for what he did with the machine, he definitely didn't show it. "Sierra, I made sure myself that nothing will happen. I swear it. I double checked."

My vision became blurry and I knew I was on the verge of tears, "...and what if you're wrong dad? What happens if there's a glitch in it's system? I-It might oh I don't know...kill me?"

"I can assure you Sierra that I will make sure that you are out of harms way if there is a 'glitch in my system'." A low resonating voice filled with sincerity said quietly.

I swear I must have jumped five feet in the air. I shrieked and almost fell as I turned around very quickly. Where the hell did it come from? My father caught me. The Terminator bowed. "I am terribly sorry that I frightened you. My audio processors could hear you all the way over there. So I figured that I might help your father with explaining things."

I felt my face heat up as all eyes were on me. "Yeah." I turned to my dad, giving him a angry glare. "I'm going back to my room." With that I swiftly turned on my heel and headed out the door, slamming it closed.

~Normal POV~

John Connor leaned against the wall behind him and sighed, closing his eyes. 'I know she has a fear of the Terminators...I do, though I would never admit to it.' He looked at the Terminator who was staring back at him. 'I had a couple Terminators who were technically my guardian as well...one was like a father to me...'

John nodded his head towards the door. "Go find her please."

Without saying a word Sierra's guardian left the debriefing room and went to find his charge.

It didn't take the Terminator long to find Sierra, as he walked by a door, it caught a glimpse of a name, taking another look it saw that it was Sierra's room.

Upon entering the room the Terminator noticed that Sierra was laying on her bed face down. She groaned when she heard someone opening the door. The Terminator looked down at her.

"Go away!" She said in what anyone could guess was a sing-song voice.

She had no idea who it was, and she wasn't going to find out until she turned around to face the intruder, but the Terminator could tell that she wasn't going to do so, she was so much like her father that it wasn't funny.

"Sierra, your father has told me to come and find you."

This made her move. She quickly sat up, her eyes were right wide and she moved quickly back towards the edge of the bed away from the machine. "Get away from me." She whispered.

The T-600 moved closer reaching out to her, she needed to be calm from what the machines sensors could tell that her heart rate was going sky high and if her guardian didn't do something soon to get her to calm down she would definitely have a heart attack.

"I promise that I will not harm you. I will bend to your every order. You must calm down, my sensors are telling me that you're going to have a heart attack if you do not calm yourself."

Sierra calmed down a little but not entirely. She took in deep breaths, trying to calm herself down and as she did so she moved back to where she was on her bed, eyeing her 'guardian' making sure that it didn't do anything to cause her anymore fear. It was bad enough that the enemy was in HQ but in her own bedroom. She really must thank her father sometime.

As time passed, Sierra grew more and more tired. Being all tensed up and frightened really made her sleepy. She tried to stifle a yawn, but with no such luck.

The machine turned it's head towards her. "Go to sleep."

"I don't want to." She argued back. The T-600 walked closer to her and when she was about to scream but stopped when she realized that the machine had stopped. "Are...are you seriously supposed to follow my orders?"

The Terminator nodded. "Yes."

She yawned again, she could feel her eyelids becoming more and more heavy. She would have to finish this conversation tomorrow.

"Sleep." The machine's voice trickled in through the haze, and finally her world went blank. If the Terminator could sigh it would. This was going to be...interesting.
