The Doctor's Daughter

Chapter 7- How to get grounded for the rest of your life

"Dad, you either let me go now or you won't have a daughter anymore!" I screamed. My lips were shivering. I was about to cry. But I needed to look strong.
"No, this is way too dangerous! You know these coordinates? You know what your Mom and I did there?! We fought off Daleks and Cybermen! And I opened the void! One mistake and you get killed. Or upgraded. Or you get trapped in the void forever! Do you really want this?!"
I have never seen him so angry. It was probably because he knew better than me that he had to let me go.
"Dad, this is ridiculous!" I replied.
He started the Tardis. "Back home, now! Think about this because you will explain everything to your mother!"
I sighed. There was nothing I could do. He would rather die than let me do this. I decided to show him what he so desperately doesn't want to realize.
I put off my jacket. Now Dad could perfectly see what was happening to me.
"Do you see this? I am disappearing... The universe is erasing me! These were your words. Don't you see? The universe is erasing me because I am impossible to exist!"
After the Tardis engines stopped it was completely quiet. The only sound was Dad heavily breathing. He realized.
"But... I don't want to lose you."
Dad sat down, with his back lying against the control board. He looked scared. No, terrified.
"I will come back. Don't worry. I can fight. I know how to kill Daleks and Cybermen... I won't die... I won't fall into the void... And even when I die... I can regenerate."
Dad shook his head like a little boy whose worst enemies were his parents that wanted to leave the toy store.
"No. You won't do this. I am not losing you. We are not losing you."
That was the moment my childhood ended. Literally. Not only because I had to rebel against my Dad. It was because I realized the price of his adventures.
"You will lose me if you don't let me go!" I shouted. Tears were running down my cheeks.
"There must be another way! We'll find another way!"
I needed to think of something. Now. And suddenly there was a perfect plan B.
"You're right. I'm sorry. Let's go inside." I sighed. But I wasn't giving up. We both left the Tardis. What Dad didn't realize was that I still had the key. And this time I had memorised the coordinates- the paper was lying in the Tardis all the time so it wasn't a problem. My last problem was my father. But my perfect plan B had a solution for that.
Okay, my plan was based on the fact that I could run faster than Dad. To be precise- it wasn't even a plan. It was more like a desperate try.
I already grabbed my sonic screwdriver inside my pocket, ready to slow down and close the door between Dad and me as fast as possible. Poor dad didn't suspect anything till it was too late. But he was fast.
"Mary?! What are you doing?!"
I ran as fast as I could. When I reached the Tardis I felt relief. He couldn't stop me anymore.
"Mary, you come back now!"
the last thing I heard from Dad was a desperate scream when the Tardis dematerialised. I cried. I never wanted to disappoint him.
