Just before we begin, in Doctor Who timeline wise; this is set just after 'Listen' and before 'Time Heist' in Series 8.
In the Frozen timeline; this fan-fic is set mostly during the events of the film with a chapter set in Anna's and Elsa's childhood and the final chapter set just moments after the ending of the film.
Chapter One: History Trip
The Doctor was sitting in his large armchair. He was old, wrinkly and had what he called them; "Attack Eyebrows". He was reading a history book of Norway. Clara walked up to him.
"What ya reading?" He closed the book and ran up to the main TARDIS console. Without saying a single word. Clara followed as the Doctor began to flip some switches.
"Doctor? What you doing?!" She began to get nervous and worried as the TARDIS began to bang and scratch. The Doctor smirked.
"Norway. 1763. We're going to have a history lesson!" He proclaimed as the TARDIS began to fly into the time vortex.
Meanwhile in Arendelle, Anna was awoken by one of the castle guards. "Excuse me, Anna. Sorry about bothering you..." She got up and wasn't fully awake.
"No no no... You haven't bothered me at all..." She began to fall asleep again but woke herself up before she did fall back to sleep.
"Today's the day." The Guard sounded kind of happy with what he said but Anna didn't take it in.
"What about today?" She began to fall asleep again.
"Your Sister's Coronation, miss." He answered in a kind of confused tone. He didn't understand how Anna didn't know about her sister's coronation. She gasped. She now knew what day it was.
"It's coronation day!" She said to herself and began to giggle. Before she could get changed, a blue British police box appeared in her room.
"What is this?" Anna asked herself as she touched the TARDIS. She looked at it with great interest.
"So this is Arendelle then, Doctor?" Clara asked as The Doctor and her walked out of the TARDIS. She saw Anna who was in her nightie. "We've picked the wrong time to land didn't we?" Clara asked sarcastically to The Doctor as she tried to stare him down.
"Not at all." Anna answered as she pulled up her nightie to make sure that she wasn't on show. She looked at the duo. One was a pretty young woman with brunette hair and dimples while the man was a bit hard to tell what he looked like. He was mysterious and odd in Anna's opinion. She then asked "Can I asked who are you and how you got that box of yours in here?"
The Doctor pulled out the physic paper. "I'm The Doctor and this is my fellow..." He struggled to think of what he could describe Clara as.
"Carer. Hiya. I'm Clara." Clara insisted. The Doctor looked at her frustratedly since she used that line before on a previous adventure.
"...and we're here to make sure your sister's coronation is authentic as it can be. We'll be watching it to make sure that the authenticity is at the maximum levels." He finished his explanation and smiled at Anna.
"Okay...Doctor..." Anna said sheepishly as she began to continue to look at the TARDIS. Fed up of not knowing what it is, Anna ran inside. She was stunned. It was smaller on the outside! How could that be possible? Clara followed her inside as the Doctor waited outside.
"So...yeah. We might be liars but we're actually time travellers. I hope that doesn't kill us..." Clara explained as Anna walked around the main console of the TARDIS.
"So, tell me the truth. You're actually time travellers?" Anna was still struggling to take in the information she needed to know. The Doctor walked back into the TARDIS.
"Yes in deed Princess." He walked up to Anna and kissed her hand. It felt awkward. "Princess, all we would like to do is to stay the night for the coronation today then we'll be on our way..." She understood everything now. Doctor and Clara were here to see Elsa's coronation! She was happy for them to stay. As the saying goes, the more the merrier.
Anna, Doctor and Clara walked out of the TARDIS as the Doctor locked it up. "Is that fine then, Princess?" Doctor asked.
"Of course and by the way, I prefer to be called Anna." Anna introduced herself to the Doctor and Clara then she grabbed both of their hands and said in a very giddy tone "Let's go then!" The Doctor let go of Anna's hand.
"I'll stay here. I would like to explore the castle for a bit." He explained. Anna looked sad that he wouldn't come. He turned and continued to explain "Look, you two go and do some girly stuff like hugging and that and I'll be here if you need me." Anna began to smile as her and Clara ran out of Anna's room. The Doctor on the other hand, he wanted to know more about Anna's sister; Elsa...
The next chapter goes live on Saturday to go live with 'Time Heist' and after that, each chapter will go up every Saturday to collide with the airing of a new episode of Doctor Who. Until then, if you like this story; please fav, follow and review. It motivates me to write more chapters and fan-fics like this. Until the next chapter guys, I'll leave you with a few questions for you to ponder.
Why is the Doctor here? What does he want with Elsa? Most of all, what danger is there when it seems there is none?
