Doctor who is owned by BBC. This is based off of the episode The Family of Blood. This is a completely imagined scene that happens after the doctor leaves in the Tardis.
"Ladies and Gentlemen, we deeply regret to inform you that a fellow teacher John Smith has died." The headmaster announced. Joan and Timothy smiled because they knew that wasn't true, and when someone looked in their direction they frowned, acting like he was indeed dead.
"The funeral will be tonight. All students and staff are excused to attend." The headmaster continued. Later at the funeral the students spoke of their fondest memories of him, though there wasn't a body to be buried. Just ash; or so the doctor made them believe. Joan and Timmy did not cry out, as they knew that John Smith never existed so he wasn't alive nor was he dead.
