Thank you so much for the reviews and follows! Here's chapter two. I might post chapter three later today but I'm not sure yet.

The next day, Kristoff and Anna decided that they should visit the trolls to tell them the news. The snow swirled around their sled as Sven, Kristoff's reindeer pulled them through the forest. Anna was wrapped in the cocoon of blankets that Kristoff had brought for her, fearing that she would get sick. She had promised him that she wouldn't, but as soon as she stepped outside, her entire body began to shake in the cold wind. In a matter of seconds, Kristoff had placed his coat around her shoulders, scooped her up, and carried her to the sled, where he tucked the blankets around her small frame.
"Kristoff, please take your coat back," she begged after ten minutes.
"No, I have to keep you warm." The image that haunted Kristoff everyday made its way into his mind; the image of Anna, the love of his life, frozen solid in front of her sister. He vowed never to let that happen again, to protect her, to keep her warm.
"I'm warm, but you're freezing," Anna said, wiggling out from underneath the blankets to remove his coat and place it around him.
"Anna-" he began, but before he could protested, she kissed him and snuggled up to his chest, pulling the blankets around herself once more.
"I love you so much," Kristoff told her.
"I love you more," she giggled.
"Impossible, nobody will ever love anyone as much as I love you."
"Except for me." They were both laughing and without realizing it, Kristoff let go of the reigns, allowing Sven to run wildly through the trees. Suddenly, the reindeer took a sharp turn, sending Anna flying from the sled.
"Anna!" Kristoff cried, leaping after her. Sven immediately stopped to wait for his friends to return.
Kristoff searched frantically through the snow, but Anna was gone. As he dug through a pile of white fluff, he heard his wife's familiar laughter coming from behind him.
"Anna?" he called.
"I'm right here!" she answered, her heading poking out of the snow. Kristoff rushed over to her and pulled her out of the snow.
"Oh, thank god! You scared me, Anna!"
"Brrrr. It's cold," she said and he attempted to give her his coat again, but she refused. He wrapped her in the blankets once they got back to the sled.
They reached the home of the trolls, Kristoff's adoptive family, within an hour.
"Kristoff! You're home! We've missed you so much, baby," Bulda, his mother called, waddling up to them as fast as her short legs could carry her, "and Anna! You get prettier each time I see you."
"Awe, thank you, Bulda." Anna blushed.
"You two never visit unless there's a reason. So spill it; what do you need to tell me?"Bulda asked. She had a way of knowing things and Anna was pretty sure that she had already figured out why they had come but wanted to hear it from them.
"Well, Mom, we do have some news," Kristoff said, "Anna's pregnant!"
"Oh my goodness! Come here, honey, let me feel," Bulda ordered, beckoning Anna with her stone hand. Anna knelt down, letting the little troll woman place feel her slightly protruding stomach. Bulda closed her eyes and sighed as she returned her hand to her side.
"I have to go get Grand Pabbie. I'll be right back," she said, fear creeping into her voice.
"Mom, what's wrong?" Kristoff called after her, but she was gone. The smaller trolls were asleep, which Kristoff was thankful for, as he was too worried to be mobbed by his little siblings.
"Everything will be okay, Kristoff." Anna placed her palm on his face and gave him a slight smile. Her eyes, two blue-green orbs swirling with worry, disagreed with her words. Kristoff leaned his head down to lightly kiss the top of hers. Their fingers intertwined as they watched Bulda walking back towards them, followed by another small, chubby finger.
"Hello, Grand Pabbie," Kristoff said to the elderly troll king.
"Hello, Kristoff. Hello, Anna," Pabbie muttered hastily. Anna dipped her head in greeting.
"Feel the child," Bulda told him.
"May I?" he asked Anna.
"Of course." She tried her best to ignore the sadness in his voice and smile as his hand rested on her belly. His face was calm for a moment, but then it turned shocked.
"I fear you are right, my daughter," he said to Bulda, who made a noise somewhere between a gasp and a croak.
"What is it, Grand Pabbie?" Kristoff asked as panic washed over his face.
"Anna, your child shares your sister's ice powers," the troll answered.
"That's okay. Elsa can teach it to control them," Anna said, relieved.
"If only it was that simple, my dear princess. This child harnesses a power much greater than Queen Elsa's. It is incredibly rare for a child to be born with this ability, but for one to possess it inside the womb; well that's practically unheard of. It brings me great sorrow to tell you this, but your child is freezing you from the inside out, Anna. It will be incredibly difficult for you to survive this pregnancy.
"But you can save her, right?" Kristoff asked, unwilling to believe the tragic news.
"I can not; I'm so sorry. Hope is the only thing you two have and you must cling to it."
"Anna, no." Kristoff pulled his wife to his chest, a tear rolling down his cheek.
"It's okay, Kristoff. This is out of our control; whatever happens happens." Anna tried to stay calm for her husband's sake, but she was secretly struggling to keep her eyes dry.
"Is there anything I can do to save her?" Kristoff questioned.
"Keep her warm and stay with her. Love her. She needs true love and warmth. But even if you care for her well, she may not make it. I truly am sorry. I think it would be best for the princess if you two returned to the castle."
As they prepared for their second journey, Anna didn't refuse Kristoff's coat and by the time they arrived home, it was damp with her silently-shed tears.
