It's been almost a year since the last time Anna saw her sister, Elsa Arendelle. Elsa was studying biotechnology at California, while Anna stayed at their countryland, Norway. Anna hadn't receieved even a call from Elsa for almost a year. The last time she called Elsa, she said that her phone was broken, and Elsa didn't come home on Christmas, even now, on Summer. She had decided what to do, and here she was, knocking her boyfriend's apartment at a morning.

"I'm going to America," Anna said as the door in front of her opened, showing Kristoff staring at her in disbelief.

"Why so sudden?" Kristoff asked.

"It's Elsa, I'm so worried about her," Anna went in to his apartment and sat in his sofa, "She hasn't even contacted me for almost a year! I really need to go to America."

"Well then, let me go with you?" Kristoff smiled and sat beside Anna, "You wouldn't last a minute if you go there without me, you know, getting lost and stuff like that."

Anna giggled, "Okay, I kinda actually knew that you will offer yourself to accompany me, and i've booked two tickets straight to California!" Kristoff looked at Anna with eyes widen, "When are we going?"

Anna smirked, "Tonight."

"California! Here we go!" Anna exclaimed excitedly as she stepped out of the airport. Kristoff carried her bags behind her, struggling to walk straightly.

"Honey, would you mind helping me?" He sighed. Anna looked back and helped Kristoff immediately. Her face was sparkling, "I miss Elsa so much! And I can't belive that I'm going to meet her again!"

"Yeah Anna, I know she does miss you too, so why don't we just hurry and visit her?" Kristoff gave Anna a warm smile, and Anna smiled back while trying to find a cab. She found one, and they went to an address that Anna had been holding. It was Elsa's address of course. Elsa lived in a small house near her campus.

"Knock knock? Elsa~~~?" Anna knocked Elsa's house plenty of times, but there was no answer. Slowly, she turned the knob, and found it unlocked.

"I have a bad feeling about this..." Anna whispered, and she stepped into her sister's house. She gasped in surprise when she saw the inside of Elsa's house. It was completely a mess, dust everywhere, and it looked like noone had ever lived there.

"Maybe... maybe Elsa is staying in her college, or her friend's house," Kristoff tried to cheer Anna, but Anna was already in her panic state.

"If what you said is true, then why does Elsa's house is in a mess!?"

"Calm down, calm down, let's just hope for the best," Kristoff held Anna's hands. Anna took a deep breath, and then she nodded. They agreed to check on Elsa's university first. They got arrived at the University of California a few minutes later, and then they went to the head office of the college.

"How may I help you, miss...?" the secretary of the principal asked.

"Arendelle, Anna Arendelle, I'm trying to find my sister," And right after she said that, the secretary's eyes widen.

"Arendelle? You're related to Elsa Arendelle?"

"Is there any problem?" Anna asked nervously.

The secretary looked at Anna with a symphatetic look, "I'm sorry, we don't know where she is either. Actually, Ms. Elsa Arendelle had gone and quitted from our university since six months ago. We never knew where did she go, and we couldn't contact her and had a chance to talk to her. A few days after we found her missing, we got a mail from Ms. Elsa. The mail said that she was having family problems and had decided to leave the college, so that she could live with her family."

"Wait, what? You're saying that she said that she's with... with me for six months?"

The secretary was starting to be worry, "I think you should call the police."

Anna stepped out of the police station with a worried look, and Kristoff walked beside her. He was just about to call a cab, but Anna suddenly stopped him and dragged him to somewhere.

"Anna?"

"Kristoff, I won't rely on the police. It will surely takk too long, we need to do something faster, and I've been thinking about making a poster with my sister's picture and then put it all over the street," Anna walked into a minimarket and bought poster papers.

"Do you really think this is a good idea?" Kristoff asked hesitatedly. Anna exhaled and then a tear came out of the corner of her eyes, "I can't think of a better way"

And so they did put Elsa's face all over the street, and they also wrote : "If you found this girl, contact Anna xxxxxxxxx". After they had done doing that, they returned to Elsa's house and decided to take some rest. Just a few hours later, a man called and said that he had found Elsa who had seemed to be locked somewhere and was hurt pretty badly. Anna was delighted, and then she gave the man her address, because the man told her that he would help Elsa to go home. Anna sat on the living room sofa nervously, as Kristoff walked towards her.

"Anna, don't you think it's weird?"

"What's weird?" Kristoff sat beside her.

"Well, It's been disturbing me for a while. The man said that he found Elsa being locked in some place, meaning that he was trying to tell us that Elsa was kidnapped, and he had freed her from the kidnapper... But isn't it too fast? I mean... he called us just a few hours after we made the posters. He couldn't have found Elsa if he hadn't known where she was from the beginning!"

"Are you saying.. that..."

And then the bell rang. Someone was knocking the door, "Ms Anna? I'm here with the missing girl!"

Anna gulped and saw Kristoff, "Should we open it?"

Kristoff held her shoulder, "You go hide, I'll be the one who talked to him." Anna nodded and went to her bedroom, and Kristoff went to the door, opened it. A middle-aged man was standing alond behind the door, smiling.

"Shouldn't you bring Elsa here?" Kristoff asked sharply.

"Well, Ms. Elsa was afraid, and she couldn't believe that it was really Ms. Anna who was looking for her, so she wanted to check that the one who was searching for her is the real Ms. Anna."

Kristoff looked at him weirdly, "Why would she even doubted Anna? She's her own sister!"

The man was still smiling, "So... sister... huh?" After he said that, he punched Kristoff in his stomach. Kristoff exhaled, and then fell into the floor. Before he blacked out, he saw that the man's hand... it was made of metal. The man walked inside Elsa's house.

"Ms Anna? So you're Elsa's sister? Well, I have to admit, your sister was giving me trouble. She cannot be found anywhere, even I, was going to give up finding her! But you.. thanks to you, I can finally have a way to find her. Don't you wanna see you sister, Anna? I'm sure she'll come to you if you come with me," The man searched for Anna inside the house. Anna was crying inside the bedroom, below the bed, holding her mouth tightly so she wouldn't let out a sound. She was afraid. And then she saw the man's feet in front of her face, and soon, she saw his face.

"Found you," the man pulled Anna out by holding her hand tightly, and Anna screamed as loud as she could. But then suddenly the man let out of his grip, and she fell into the floor. Anna looked up, and saw a woman stabbed the man's back from behind.

"I pity you, you should have asked for a metal body, not a metal hand," the voice... sounded familiar, but Anna couldn't see the woman. The man was screaming, but then the scream faded out, as well as his eyes. The woman let go of the knife, and the man fell to the floor. The woman...

"Elsa?" Anna wiped her tears.

"Anna, are you out of your mind? Revealing my face all over the city?" Elsa grabbed Anna's hand and helped her to stand. Elsa, there's something different from her. Her beautiful long hair was gone, and what she had now is a short haircut. Her eyes seemed cold, she didn't had the spark in her eyes like the last time Anna saw her.

"You were missing!" Anna said angrily, "And now you blamed me for trying to find you? And did you just kill him?"

Elsa sighed, "Anna, we have to go now, no time to argue, pack your belongings, I'll get Kristoff," Elsa walked towards Kristoff who was laying unconsciously. Anna did just like what Elsa had told her. After Kristoff was awaked and saw Elsa and also the dead man, he asked a lot of question, but Elsa didn't even bother to answer.

Before they left Elsa's house, Anna looked back to see the dead man. Is this woman, the woman who had just killed someone without a guilty feeling, really her sister, Elsa?
