"Anna."
"Mm?"
"It's cold in my room. Can I sleep with you?" Elsa cocked her head, looking at her younger sister.
"Sure! Just don't tell Mommy and Daddy." Anna pulled the covers up and patted the mattress.
Elsa grinned, toddling toward her. Mommy would be kinda angry if she knew she was in here without supervision. It didn't matter, though; the sisters were bestest friends and nothing could tear them apart. Not even the things Anna could do. In fact, Elsa loved the things she could do.
'Why is it that you can do that, but I can't?' she would ask, staring up in wonder. Anna would shrug, 'Dunno. It'd be so great if you could, though!'
Elsa curled into Anna's impossibly warm body. "Do the thing." she whispered, giggling, "Pleaaaase?"
Anna rolled her eyes, "I'm tired, Elsie… but fiiine. Only 'cause it's too dark in here." Sitting up, Anna brought her hands together and felt her palms warm up, a tiny flame greeting the two as she opened her hands.
"Doesn't it hurt?"
"You've asked me a thousand bajillion times, Elsa. It doesn't even touch me, see? It's floatin'! But, it can hurt if you really touch it, so don't, okie doke?" Elsa nodded and stared at the tiny fire morph into a large flame, shooting into the air like fireworks.
"It's beautiful… do it again!" the older child laughed, "Do the colors!"
Anna nodded, the flames making lovely shapes and changing hues of blue, red, white and green. Elsa giggled, egging her on to make more spectacular lights. "Hold on, Elsie, I'm trying! It's g-getting… oh!"
The curtains caught fire, the rugs following suit. Anna screamed, the flames bursting from her hands. "Elsa, get the water! Quick!"
"No time, Anna! We need to get out!"
"No, Elsa, I can stop it, don't- don't touch me!"
The fire burst from her palms, and Elsa screamed.
"Mom, Daddy! Help!" Anna screamed, pushing her hands into the water bowl on her night table even if it seered her hands like thousands of paper cuts. "Mommy, please!"
They burst into the room, flames licking at the ceiling, Anna weeping, Elsa screaming in pain.
"Anna! What have you done!" her mother yelled, horrified at the monster her second born had turned out to be.
"D-don't yell at me!" Anna sobbed, a ring of fire surrounding her on the carpet. "Stay away!"
"Get Elsa to the infirmary. I'll get Anna." their father instructed his wife and watching her grab their daughter, calling for guards. He looked to Anna, trying not to show fear. "Anna. Put it out. Now."
"N-no! I… I don't know how, Daddy! It… it won't stop!" Anna wiped her eyes, hands blackened and smoking. The fire seemed to engulf her, yet left the small girl unharmed, as if protecting it's master.
"Anna, stop!"
The flames consumed the room, and the only thing he could do was shut the door and run.

"Anna passed away," they told her, "It's better that way. She can't hurt you again."
"Why don't you hate her, Elsa? Look what she did to your beautiful face." they frown, "We're not talking about her again."
Elsa wiped her eyes, going back to playing with her dolls. Anna's death had been labelled a careless one, the toppling of a lit candle. Everyone was just happy that their future queen, Elsa, was safe, even if she'd always have a burn scar on her jaw to remind her. 'She's still so beautiful,' they said, 'It's a shame such a pretty face has such a reminder of despair.'
Elsa stared at the mirror and brushed the left side of her jaw, the handprint-like mangled skin sending a wave of anguish over her. It wasn't Anna's fault. She shouldn't have asked her to do the magic. She should have just stayed in her bed. Why didn't she stay in her bed?

"P-please, let me out! I promise, I'll be good! I can control it, see?" Anna begged, the six year old weeping and showing her bare, blackened palms.
"Anna, we can't risk it. You could burn down the kingdom!"
"At l-least let me see Elsa-!"
"Elsa doesn't know you're still here, Anna." The Queen whispered, "You would put her in danger."
"B-but, Mama!"
"No buts!"

Elsa often hears crying from Anna's room, but she tells herself it's just her imagination being cruel. The door remains locked, as always. No one is allowed in.
No one is allowed out.

"Anna?" Elsa snuck over to the room one night, "I might be crazy, but I miss you. Sometimes I wonder… if you're still in there."
Anna sniffed, pressed against the door. "E-Elsa?" Mom and Daddy would kill her if they knew about this, but she had to talk to someone. Anyone.
"A-Anna!" Elsa quickly covered her mouth, not wanting to alert any guards. "Anna, are you okay? You're… you're not dead?"
"Of course not! You of all people know I'm fine with fire! Mom and Daddy are afraid I'll hurt you again. So… I have to stay here. And be quiet. It's okay, though! They bring me cookies and dollies and everything I could ever want."
"Anna… that's not okay! They told everyone you were dead! They told me to… forget about you… to hate you for what happened." Elsa let her tears fall, listening to her sister's voice for the first time in over a year.
"...Elsa, I think you should go. I gotta go to sleep, anyways." Anna sighed, angry flames dancing on her palms. Of course. She knew she was a monster, hurting her sister like that. She was painfully reminded of the reason she was locked away; it was better this way. For everyone.
"W-what? But I just got here!"
"Please, Elsa. And… don't come back."
