Just a tiny thingy I had stuck in my head for a while…
Disclaimer: Sadly I will never see this on a real episode of Doctor Who, 'cos I don't write for 'em.
"Doctor Foreman, come take a look at this!"
I walk over to the nurse. "What is it, what's wrong?"
"You've got to check this out!"
"What…? But that's…"
"A binary vascular system."
"A binary vascular system? But that's… impossible. What's his name?! What's the patient's name?!"
"He's called John Smith."
"Impossible," I walk closer to the observation window. I see a pale man with longish brown hair and side-burns. He smiles and waves at me. I decide to walk into the room. I talk with him for a while while fiddling with the watch in my pocket. I was found with this watch when I was little, walking around London, confused and alone. Talking with him triggered a spark in me. Familiar yet different, as if I was looking at a man I once knew, but with a different face. John Smith, I recognized that name, but dismissed the thought, seeing as it is a quite common name.
"So you're the impossible man. The man with the binary vascular system?"
"Yup. But most people just call me the Doctor."
Why did that sound familiar to me?
"And what's your name?" he continued.
"I'm doctor Susan Foreman." With that his jaw dropped and his eyes widened. For a moment I was confused, but I continued, "Do I know you from somewhere?"
"I should hope so, I see you've regenerated, and found some way of cloaking yourself, but is it really you? Susan Foreman, my Susan Foreman?"
And that's when the watch in my pocket finally opened, for the first time, and the truth was revealed. Memories went rushing through my brain, I remembered a junkyard, a whirring, and a … phonebox. "Grandfather?"
"It really is you, my Susan Foreman."
