We brought Harry Potter, The 9th 10th and 11th Doctor, Rose Tyler, the Ponds, River, Jack Harkness, Sherlock, John, Sam and Dean Winchester, Castiel, and Merlin all together in a room. Watch the randomness. And, to add some spice, we created an alien demon hybrid committing murders on witches and wizards together. Merlin's just there for fun. Rated T for Dean's potty mouth and us.
