This is my first Dr Who fic, so constructive criticism please!

Apoligies in advance for any incorrect spellings, my laptop has no spellcheck.

Clara's POV

"But why? How, even!" The Doctor continued to argue.
"It's just a song! Why are you getting so worked up about it?"
"Because it doesn't make any sense! How can someone be titanium?"
I huffed in annoyance.
Basicaly, my phone started to ring, and my ringtone is 'Titanium'. Upon hearing it, The Doctor snatched up my phone and began to argue with it, saying that someone couldn't be titanium.
"It's a metal! You can't be a metal Clara, I am very concerned about your scientific knowledge!"

"It doesn't mean you are a metal, it just means you're tough, it's just a song Doctor, let it go!" I lost all of my patience and snapped.

"Don't even think about singing that song while you're on my ship Clara!" he suddenly changed the subject.

"Since when did you start watching Disney films?" I ask, alot more calm.

"I was investigating." He continues to flick switches on the TARDIS.

"A Disney film?" I raise one eyebrow at him.

"What if it's not just a film Clara? What if it's based off something true?" He walks up to me.

"It's based off a book, that's it."

"But what if the book was based off something true? What then?" he continues.

"Please don't tell me we're going to investigate?" I moan.

"Oh come on Clara, learn to have a little fun." he smirks, pulling back the last lever as the TARDIS begins to wheeze and rock.

This may turn into a series, I dunno.
