The TARDIS rumbled as the Doctor was thrown this way and that. After his regeneration, the newly decorated TARDIS seemed to sway more. Maybe she didn't like the bowtie? Well, he did, and that's all that mattered. But, he did have a more important problem at hand. "Where the hell am I going-" he asked himself, before gripping onto the console for dear life as the TARDIS swayed again. "And why is she having such haarrrdd time?!" he yelled. I'm talking to myself again... he thought, then the TARDIS was finally stabilized. "Are we there, ol' girl?" he asked her, earning a hum in the back of his mind. He took that as a yes, and began to open the TARDIS' doors. What he saw next, he simply didn't believe...

She wasn't used to it. She wasn't used to any of it. She was so used to being isolated. She paced back and forth in her room. She had tons of paperwork to do, as a queen, but she ignored it for now. Her window blew open, for the second time that day. "Why does this thing keep happening?!" she growled to nobody in particular. Suddenly, frost began to cover the window. She looked at her hands, then the window. That wasn't me, she thought, before a smiley face was drawn on the window. She backed away, and ended up tripping. She fell on her back, but ignored the pain. I-is someone here? she asked her mind what her lips couldn't seem to. "H-hello?" she stammered, attempting to get up. She felt something-or someone-grab her hand. She was forcefully pulled up, and she looked around incredilously. "Who's there?" she demanded, stomping her foot. "How are you invisible?" She looked in front of her as floating ice words began to form in front of her face.
It's because you don't believe.

"Believe what?"
Believe in me.
"Who are you?"
You wouldn't believe me if I told you.
"Try me."
Jack Frost. She took a few steps backward. "Jack Frost?" Elsa remembered that her parents would tell Anna and herself stories about him...She'd always secretly hoped that he was real. She always secretly half-believed in him. Someone like her... she wouldn't be alone. She blinked, and he became visible.
"I knew you'd come around."

The Doctor walked up to a random citizen. "Hello, crazy question, can you tell me what the full date is?" The citizen told him, and he nodded. "July you say? But it's snowing..."
"You don't know where you are?"
"Not a clue."
"You're in the kingdom of Arendelle, sir."
"Arendelle? Hm, never heard of Arendelle before..." he muttered. "Thank you for your help!" he called to the citizen as he began to the castle doors. As he opened them with his sonic, he had looks coming from the entire town. He walked in nonchalantly, then closed the doors. He walked about the halls, examining the architecture. "Oh, this is brilliantly made..." he mused, running his fingers gently across the frame of a photo. He heard a few footsteps on the floor above him. Perfect, somebody's here that I can talk to! He began to go up the spiraling staircase to reach the top floor. He stopped as he neared the top. What if it's an alien? Oh, who am I kidding? Give me a Dalek any day!

"B-but you're just a story!"
"If you really believed that, you wouldn't be able to see me." She shook her head, then heard footsteps. "Y-you stay here." she stammered, then regained her composure. As Jack Frost, guardian of the Snow Queen since she was a small child, he was obligated to follow her, and he did. She walked out to see a particularly skinny man with a strange thing around his neck and a suit...and also some weird little device in his hand. He also had floppy hair, he'd noticed."Oh, hello!" he greeted with an accent. Neither of them had heard that accent before...
"Who are you and how did you get in my castle?" she demanded, stomping up to him and getting so close to his face their noses were almost touching -even though she was on the tip of her toes, and wearing high heels- and she frowned at him. He wasn't phased at all. He poked the top of her head, and spun around her, catching her by suprise and causing her to turn around, wobbling. Jack flew over to her and stabilized her, then walked angrily over to him. Jack attempted to turn the strange man around to face him, but his hand went right through his shoulder. He pulled back in realization. The man turned around anyway, then simply stated, "I'm the Doctor."
"Doctor who?" He simply smiled and walked up to face her again
"That's a dangerous question." He smirked, then he looked to see a door, that another voice was coming from. "Elsa? Who are you talking to?" She called, then the door flew open to reveal a girl, otherwise known as Anna. She saw the man and rushed over to him. She poked his bowtie uneasily, then poked his hair. He gently slapped her hand away, then took a few steps back to regain his personal space. "Who are you?" That's happened twice now, today.
"He calls himself 'the Doctor'." said Elsa, walking next to her sister and frowning at him.
"Yeah, but Doctor who? Shouldn't a last name-thingy be there? Like, Smith or somethin'?"
"Sometimes I go by Smith, yes, but I'm just the Doctor."
"Yeah," she repeated, mockingly annoyed, "but Doctor who?" She crossed her arms.
"You know, I never realized how much I loved hearing that until now. "
"Hearing what?" He just shrugged, and began to head towards the staircase.
"S'pose I'll go if you don't want me here." Elsa rushed over to him and grabbed his sleeve.
"No. Who are you? You cannot leave until I figure out who you are." He twirled around and began to walk down the halls, past Anna and the unseen Jack.
"Brilliant!" he yelled as he walked down the halls, causing the three to stare at him incredilously. "But who is he?"
"I have no idea."
