Demon in London (Superlock Crossover)

One early morning, Sam and Dean Winchester receive a call from a man by the name of Mycroft Holmes and find themselves hunting a demon in London.

After the Fall, Sherlock Holmes wasn't the same person he was two years ago. He's been meeting with strange people and purchased a lot of dangerous chemicals. This concerns Mycroft and he discovers that his little brother has changed after the Fall. What could Sherlock be up to?

Not long after Sherlock comes back, John mysteriously disappears and this raises many questions. Where has he gone? Has he been kidnapped? Will he be found alive?
