It's seems you've stumbled into the Superwholock universe. Boy, have you got an adventure ahead of you.
When Sam and Dean investigate disappearances and crashes of planes, they have no choice, but to take to the sky themselves. The plane they inspect takes them to England, where they meet Sherlock Holmes, John Watson, and a strange man by the name of the Doctor. Together, the five all solve a case that is stirred in London, involving each of their worst enemies: Lucifer, Moriarty, and The Master.
I do not own anything Supernatural, Doctor Who, or Sherlock.

Credit those who own what I do not.
