Disclaimer: I don't own any Doctor Who characters
The Doctor sits within his T.A.R.D.I.S. silently and alone. His companions were gone at the time and he was lonely. With a sigh he walked over to the monitor of the T.A.R.D.I.S. and began to type. Somehow, he had ended up on a website he had never heard of before. He blinked at it with questioning brown eyes before clicking on the search bar and typing in 'The Doctor'. He was surprised as he found many original character stories and slash, he even found people 'shipping' him with the master, which he later found out meant supporting the as a couple.
Besides the few pairings that terrified him and a few that were about some things that would actually happen in his future, he was very happy to see them. He was sad to see that he wouldn't be able to take everyone with him, but he really wished he could have. He just couldn't, they were of a different dimension, he would never be able to take any of them with him, ever. With a smile he looked away and looked up at the T.A.R.D.I.S.
"Alright old girl," The T.A.R.D.I.S. hummed as if to ask 'yes'. "Lets go make all these humans proud and go find someone else to take along with us." The Doctor says pulling a few leavers.
The T.A.R.D.I.S. disappears from the spot it was in and reappears in a different dimension entirely. The dimension of which, he was a fictional character.
The Doctor runs out of the alley way he was in. He looks around quickly and a bright grin spreads across his face, it didn't matter that this wasn't supposed to happen, he just opened his mouth and yelled.
"Hello world! I'm The Doctor!"
