Elsa and Anna were walking around looking. Anna was singing while they looked.
Then they heard something and turned around to see Olaf.
"Hey Olaf, umm, maybe just one of you should do it." Elsa said closing her hands together.
"I agree, she's a little pitchy." he said looking at Anna.
Then they felt the wind go off.
"Hey, Gale's back."
So they followed then they ran and saw a ship.
They stood there in shock with Elsa holding onto Anna's hand.
"How can it be?" Elsa wondered.
"What is it?" Olaf asked.
"Mother and father's ship." she said.
"But this isn't the southern sea." he said
"No, it isn't." Anna said then started to run.
When they got inside they stopped and looked around it.
"Why is their ship here? How're they here?" Anna asked walking around.
Then she bumped into a table.
"It must have been washed in from the dark sea." Elsa said looking down at something else.
"What would it be doing in the dark sea?" Anna said confused.
"I don't know." Elsa said through a cloth.
"How did the ship get through the mist? I thought nobody could but us, unless... Nobody was on it." Olaf said looking around.
Anna stood there and Elsa walked over to her.
"There's gotta be something here." she said and turned around. "Wait, wait, look around. Every Arandellian ship has a compartment, waterproof."
She started walking and looked around.
"That's very clever. Although that makes me wonder why they don't just make the whole ship waterproof here!" Olaf said.
The two of them continued to look around.
"I don't know, but look, this is mother's handwriting!" Anna said.
"The end of the ice age, the river found but lost magic's source. Our sources?" Elsa said.
Then Anna grabbed the paper and looked at it.
Elsa found something else.
"It's a map." she said and put it down. "They traveled north Planned to cross the dark sea to.. Ahtohallan."
"It's real?" Anna said shocked.
"Ahtoho- what?" Olaf asked.
"It's a magical river said to hold all the answers about the past." Elsa explained while Anna stood there thinking.
"Do you reinforcing my water has a memory theory? Water has memory." Olaf said.
Then Anna headed to the light on the floor and put her hands on it letting some fire on the ground.
"Anna?" Elsa asked watching her.
"I wanna know what happened to them. Ahtohallan is the source of the magic." she said and let some fire go and started to see a metal form of their parents and saw a wave going over them.
"We keep going." Agnarr said.
Anna started to cry and walked away.
Elsa went after her and saw here leaning on a tall rock.
"But Anna... Anna! Hey hey, what are you doing?" she asked with a hand on her back.
"This is my fault, they were looking for answers about me." Anna said.
"You are not responsible for their choices, Anna. I have powers to. So technically they were looking for answers about both of us."
"No, just their deaths. And you had control of yours but I didn't." she said and walked away.
"Stop." Elsa said going in front of her. "No, Yelena asks why would the spirit reward Arendelle with the magical queen and princess?" Anna stood there confused. "Because our mother saved our father. She saved her enemy. Her good deeds was rewarded with us."
"You two are a gift."
"For what?"
"If anyone can resolve the past, If anyone can save Arendelle and free this forest, it's both of you. I believe in you and and me. More than anyone or anything." she said with her hands on Anna's.
Anna turned around and thought.
"Honeymaren said there was a fifth spirit. A bridge between magical nature and us."
"A fifth spirit." Elsa said.
"That's what's been calling us from Ahtohallan. The answers about the past are all there."
"So we go to Ahtohallan."
"Not we me. The dark sea too dangerous for us both."
"No, we do this together. Remember the song, go too far and you'll be drowned. Who will stop you from going too far?"
"You said you believed in me, that this is what we were born to do."
"And I do not want to stop you from that. I don't want to stop you from being whatever you need to be, I just- don't want you dying trying to be everything for everyone else too."
"Don't do this alone. Let me help you, please. I can't lose you Anna!"
Olaf stood there frowning.
Then Anna gave her a hug.
"I can't lose you either, Elsa. Come on." she said holding out a hand for Olaf who walked over and hugged them back.
But then Elsa made an ice boat and got Anna and Olaf in it.
"Wait what? What are you doing? Elsa!"
Then she started to go down while Elsa frowned.
"No, no..."
Then Anna tried to melt it with her fire powers but it was to thick.
'Ulg! Why did she have to be more powerful then me?'
"Olaf, help me stop it's to thick for my fire powers! Give me a hand!" So one of them tapped her shoulder and she took it. "Hang on!" Then the hand grabbed a part of a tree. "Oh no." Then they were in the water. "Come on!"
"Anna, this might sounds crazy, but I'm sensing some rising anger." Olaf said.
"Ah, now I am angry, Olaf. I promised her we'd do this together. And she used her powers to make a boat to strong for my fire, she's to protective!"
"Yeah, but... What I mean is I'm sensing rising anger in me."
"Wait, you're angry?"
"I think so. Elsa pushed me away too and didn't even say goodbye."
"And you have every right to be very, very mad at her."
"And you've said some things never changed, but since then everything does nothing but change."
"I know but look, I'm still here holding your hand." she said with his hand in her's.
He smiled.
"Yeah, I think that's a good point Anna I feel better, you're such a good listener."
Then she covered his mouth.
"Shh, shh, shh!"
Then they went past the giants.
"Oh the Giants, they're huge!" Olaf said.
She turned around and tried to row them away but went in a circle and around the rock.
She saw that something was open and started to row.
"Hang on Olaf." Then they went straight and started to go down. "Try not to scream."
While they went down he quietly yelled.
She let a fire on a twig with her powers. Then saw a carrot.
"Found it!"
She put it on his face.
"Thank you." he said smiling. "Where are we?"
"In a pit, with no way out but with this spooky pitch black way in." she said looking around.
"Come on, it'll be fun. Assuming we don't get stuck here forever and no one ever find us." he said walking forward.
"You started it and I gave up. But the bright side is Elsa gotta be all out better than we are."
"Of course. Glaciers are rivers of ice Ahtohallan is frozen I hear you, and I'm coming."
