You were just scraping your cats wet food into their bowl, before a young man ran up behind you, grabbed your shoulders, and slammed you to the wall. You panicked, but he covered your mouth, speaking with a rushed British accent. He was scared, and you didn't know if he was going insane or you were.

"You don't know me but I know you. You can call me the Doctor. There's something bad coming for us, it looks like it can't hurt you but oh yes it can. You have to come with me."
