A Supernatural X Welcome to Nightvale crossover. See Sam, Dean and Cas venture into the mysterious town of Nightvale with no knowledge of what lies there and what does not. [Disclaimers: I do not own Supernatural or Welcome to Nightvale and all rights are reserved to their respective owners. Also, as of now I'm only on season 9 of Supernatural and about episode 16 of WTNV but this does not take place at any particular time in either of these things.]

When Carlos goes to Gravity Falls to meet Ford Pines and takes Cecil with him, everything goes well, that is, until they discover that they were followed by a certain someone. Chaos can only follow.
