"Wohooooo! That has been the most exciting thing I've ever done!" Ahtohallan yelled.
"You should have flown on a dragon. Now that's exciting!" Hiccup assured.
"Niw thit's ixciting…" she made a mockery. "I have flown and fought and experienced in twenty-seven years more than you in a few hundred," she continued with the Hiccup childish imitation. "I'm so sorry. I didn't mean..." Hiccup tried to say regretting his words.
"It's Ok, Viking. I only was teasing you! It's not your fault that I had lived all my life being a huge piece of ice." He smiled back feeling better. "It's fine. I'm gonna living now," she said as she started to climb a tree. "So you are human now?" Astrid asked looking the way she jumped off a branch to the ground.
"Hum… Not at all. Since today I was a spirit. The spirit of the memories to be more exact. I was linked to the glacier but I've given up eternity in this world in exchange for living life. So now I am halfway between a human and a spirit, just like Elsa. My soul is the same and so my powers, but now, my existence in this world is limited by a human body. "

A dense silence invaded them while they just were dedicated to preparing a fire around which to sleep.

"You will not regret it?" Elsa said finally breaking the silence.
"Who knows… But I just… had to try."
"Good luck, then," Elsa said rubbing Ahtohallan's arm.
"I count on you for it," she answered with a wink before she snuggled up to rest near the fire.

Seeing that, Astrid and Hiccup embraced and tried to sleep too and Elsa rested her back on a stone and watched her companions until she fell asleep as well plunged into a warm sensation.

The sun was rising and Elsa slowly opened the eyes. In front of her, there were their friends perfectly tangled and sound asleep at the foot of the drowned remains of the bonfire. And, by their side, the mysterious girl. Hallan, huh? She was still sleeping too so she took her time watching her.
Her long sparkling hair seemed soft and she couldn't say what color it was. A magical mix of greens, blues, and pinks made it looks like the northern lights. Smooth flawless skin and these playful eyes that she could remember with all detail: gray, almost white, like the glacier itself. They were also bright and full of illusion like children's, and sweet and serene at the same time. She couldn't forget them.

Elsa shook her head.

"Time to find the breakfast," she said getting deeper into the forest.

When the three sleepers woke up, the food was prepared and the remains of the bonfire were cleaned up.

"Have you sleep at least?" Hiccup answered Elsa stretching his back and rubbing his eyes.
"Enough," she said nodding.
"I'm gonna eat?" Ahtohallan said in disbelief. "I'm gonna eat! I can't believe it!"
"Can you?" Astrid asked.
"Of course I can! I have a body, right?"
"Then, let's eat. We have a journey to do," Elsa smiled.
"Yeah!" Ahtohallan exclaimed standing up with a jump.

In a few minutes, they had devoured all the breakfast and, by the midday, they had made their way through the forest until arriving at the fjord.

"So… now what?" Astrid asked hoping Elsa had a plan.

Elsa closed her eyes and the water spirit came out of the water and revered her. She returned the bow and then created a graceful iceboat that could fit all four of them.

"Could you please take us to Arendelle?"

The horse splashed in the water again and the four got on the boat without knowing well what was going to happen. When all they were accommodated, a big wave raised the boat and moved it at full speed by the fjord.
Their yells of "This is amaziiiiiiiiing!", "So cool!" or "Yeahhh!" could be heard throughout the forest. When they realized, they were at the foot of the castle and, soon, they were standing in front of the open gate.
