This is told from Legolas' side. Sorry it's a bit short.
She told me her whole story. "So, that explains him." I pointed to the snowman.
"Yes," Elsa sighed. She looked at me and smiled. "That's why I was so persistent in going home, but it seems I'll be here for a bit longer."
She looked deeply into the fire. Her eyes were almost closed. What she was thinking, I couldn't tell. Just then Aragorn came back with a rabbit. He cooked it, we all ate it. After that Elsa sat next to me. After watching the fire for a bit she fell asleep. Aragorn took watch that night.
In the middle of the night I was awoken by a noise. I slowly grabbed my bow and an arrow. I sat up and turned around. Olaf was there. "What are you doing?" I said.
"I wanted to stretch my legs."
"Well, just don't come up behind me like that!"
Olaf sat next to where the fire was. Though, the fire was now so small that it was almost out. On the other side I could see Aragorn staring intently at me. He glanced at Elsa, and back to me. I looked at her. She was lying right next to me. A smile was across her face as she lay next to me.
"She likes you, even if she doesn't realize it, or you. Don't break her heart, Legolas."
"Aragorn, she belongs in Arendelle. She belongs with her people."
He looked away with a solemn air about him. I slowly fell back asleep.
I woke early in the morning the next day; it was just before sunrise. I bent over Elsa and gently shook her. "Elsa, Elsa, time to get going," I said. She opened her eyes and looked up at me. Slowly she got up and looked longingly at the sky.
"It's beautiful, isn't it? The sunrise," She said to nobody in particular. Her white hair shimmered and glistened in the morning sun.
"Morning My Lady," Aragorn said. He was packing a small pile of different things into a small backpack. "Here!" He through an apple at me. "Breakfast," He said with a small grin. He gave one to Elsa.
We ate our small breakfast and set off. Just as I was starting to wonder as to where Olaf was he appeared behind me with a big grin. "Hay! Let's go!" He said.
We walked off through the dark of Mirkwood. All wondering what woes would befall us, evils, joys, loves. We were going on a voyage to stop evil, unaware of what was to come in the time following.
