A/N I decided to start a new story, because of a horrible bout of writer's block for my other one. I love Jelsa so much; I decided to give my take on it. This is Frozen Heart.

Chapter 1.

Prologue.

March, 2, 2005.

I followed Debs down the hallway. We turned into the interrogation room. I heard yelling, someone was putting a fight. I looked through the mirror to see a …boy? He didn't much older than me. He was a decent fighter. I smirked. I could take him easily. He was rash, probably arrogant. A brute. Kerensky got him a headlock. He was handcuffed, and sat down at an interrogation table. He was cute. Wavy brown hair, a nice tan. That would disappear soon enough. He was thin, good height for his age, I was guessing thirteen, maybe fourteen. And very lanky. He looked up, and his eyes… they were beautiful. Such a deep blue. So…mysterious. His face was bloody and pale. The mirror that separated us was two way. He could see us, as we could see him. He looked at me. His face was contorted in pain. I wanted to help him. But I would be breaking protocol. I requested to talk to him, luckily Debs was distracted, and she let me. I walked in, and he looked up. His smirk was faint, but still arrogant. "Hi." He grunted at me. I took a seat across from him. "What's your name? Jack. Well, Jack how old are you? Thirteen. I'm twelve. Hello twelve." I giggled. He actually smiled at me. "My real name is Elsa." I got up, and freed him. "Why?" He looked at me. "Because, you needed my help. Yeah." He pulled me into his arms. He was cold. Just like me. I smiled. "Thanks Elsa. You're welcome… Jack.

Beep-Beep-Beep.

I groaned. I glanced at my clock. 7:00. Seriously?! I got up and popped every bone possible in my body. I sighed in relief. "Seven in the Monday morning, not my idea of a good start to a day.8" I walked out in pajamas. Wake me up too early, I'm not changing. I checked my communicator, meeting in library, hurry! Rolling my eyes, I hurried to the library. I got inside, and shut the door behind me. Debs looked up and pointed to a seat. She gave a look over and shook her head. I WAS only wearing an oversize AC/DC shirt, and shorts. Jack wasn't much better, a muscle shirt and snowflake printed boxers. He winked at me, and I felt my cheeks warm up. Just as I sat down, we were getting lectured. "Honestly you two could dress professionally. In business, or even your gear, But nooo. It has to be messy hair and pajamas. You two are supposed to serious agents of the government. Not annoying teenagers! Can't we be both?" Of course he has to be a smart alec. "Jackson, Nikolai, Frost." Debs voice was dripping with anger. I had to stifle a giggle. I failed. "Elsa, René, Arendelle.'' I bowed my head. "I know you guys are young, but you were raised to carry yourselves with dignity. And constantly breaking protocol, - Started the meeting without me?" The supervisor asked, she was followed by Phil, our 'babysitter'. I never liked her. She was in her forties, but she carried herself with the dignity of an ageless queen. Phil, on the other hand was a balding, annoying, bossy coward. "Supervisor, so glad of you to join us. Good morning Debora." What's so good about it, you're here. "Now that I am here, we will continue the meeting. Phil? The files." She held out her hand. "Now, let's see… Elsa, René, Arendelle, age seventeen, date of birth unknown, location of birth unknown, parents unknown and current ranking in the agency…first rank?" She looked up at Debs, and glared. "The other file. Jackson, Nikolai, Frost, age eighteen, date of birth January Third, nineteen ninety nine. Born in St. Victor's hospital in an untraceable country, parents unknown, current ranking in the agency… first rank?" Her voice was shrill. "How, how? These two are delinquents, trouble makers, how are they ranked so high. Because we have a good number of bagged and tagged paranormals. And we have hardly every kill one, maybe two every other month. Agent Frost, don't you dare smirk at me like you're smarter than me. He just was giving an explanation on our track record. No need to be snappish." She gave me the glare of death. "Agent Frost, Agent Arendelle. You are dismissed." We nodded and left. We leaned against the wall and slid to the floor. "Huh, do you think we raised her blood pressure much." He asked me, smirking. "Yeah. Hey Jack-

Beep-Beep-Beep. We stood up. "Duty calls." I said. We ran down the hall to our rooms to gear up. I wore a body suit, with gun straps on my thighs, and my sword sheath on my back. I slipped on my fingerless leather gloves, and tied my hair up in a bun. (A/N Elsa's outfit is like the Black Widows in Avengers.) I ran to the weapons room, and grabbed my two colts, sliver edge rapier, and extra ammo. I slid my daggers into my boots, and grabbed my mini communicator and placed it on my ear. "All set?" Jack was already geared up, in a sort of military meets spy outfit. He preferred AK 47s and a metal beating stick. "Let's go." Just as I said that Phil showed up. "Yay, Unkie Phil is here", Jack's voice thick with sarcasm. "Come on load up, load up. Bossy old Codger," I heard Jack muttered. I elbowed him in the rib cage, as we got in the van. "What's the problem? A disturbance in a church on seventy fourth and cherry blossom street…um, Agent Arendelle. So no vamps or werewolves today. Let's settle in then." 'Unkie' Phil said.

Jump cut.

We loaded out and snuck into the church. I smelled something revolting. A strange mix of blood and… something I couldn't place. "It's quiet…too quiet. Stop being so overdramatic Jack." I heard rustling, and growls. I turned around as something jumped on my back.

A/N I think stopping here is pretty good. I don't know if I'll continue the story. Let me know in your reviews. BYE! XOXO LUV YALL
