Bones/Sleepy Hollow Crossover Trailer Teases 'History-Making Discovery'

“It’s Halloween. All bets are off.”

Agent Booth, that might just be the understatement of the year.

Fox has released a trailer for its upcoming Bones/Sleepy Hollow crossover event (airing Thursday, Oct. 29, at 8/7c), and one thing is clear: Booth, Brennan, Abbie and Ichabod have serious communication issues.

The two-hour event finds the foursome collaborating as the discovery of human remains leads to the return of one of Crane’s enemies. But, as the trailer above indicates, solving this particular case won’t be a smooth operation.
