A crossover story of the Tenth Doctor and Supernatural. What will happen when the two worlds collide? Comments are greatly appreciated :D

Now that Cas is human, some things are a lot harder to do, but it has is plus sides. Feelings, for one thing, are both pleasant and not pleasant, except when they involve Dean. Nor Dean, Cas or Sam know whether Cas will ever get his grace back, and what is going on with Metatron in heaven. Luckily, they get some help from Charlie and a certain other angel. Together, they try to do what's right, and it leads them to doing things they never thought they'd be doing. Word count: 37k

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. I do not own any of the pictures or videos. Credit those who own what I do not. Yes, the cover has been changed.
