"Hello, are you The Doctor?" said The 10th Doctor "The name's Smith, John Smith. I couldn't help noticing that fine contraption you have there. May I have a look inside?"
"Excuse me, but do I know you? You look very familiar. Wait a minute; you're The Master, aren't you? You think you could get into my good books with that cunning disguise, then think again!" said The 5th Doctor.
"No, no, no. I'm not the Master. I'm you! In your tenth incarnation." said The 10th Doctor before he was killed by himself. That would have been an awkward funeral!
"What, that's insane! Your not me you skinny idiot! What on Earth would make you think that?" said The 5th Doctor, Adric, Tegan, Nyssa and Aimee were very confused by this surreal argument.
"I am you, I swear! Why would I make something like that up?" said The 10th Doctor.
"Go on then, prove it!" The 5th Doctor said with a smug look on his face. The 10th Doctor whispered something into The 5th Doctor's ear. The 5th Doctor had a shocked look on his face as The 10th Doctor pulled away.
"Oh my giddy aunt, you're me! Why are you here?" said The 5th Doctor, very excited about meeting himself.
"The Tardis brought me here, I was trying to get to 21st century London but I went a bit off course." said The 10th Doctor with a grin on face. Suddenly, a scream was heard not far from The 10th Doctor's Tardis. The six of them sprinted down the narrow alleyway and round the corner. They were quick, but not quick enough; a large portal had opened right by the Tardis. But they found no body or any trace of a death. There was only one race of creatures that could cause this. The Reapers.
