A few days ago, as we reported he posted this: writing Bones in Florida... Land of the free, home of the grave.
Well, today he states in another (not really a standalone spoiler) that: I'll spill (coffee) on him (Hart Hanson) tomorrow.
Which means: Looks like a future case of BONES will have something to do with Florida (as Stephen is still in California). A person? Evidence? B&B on the road? Yay for Stephen's cryptic clues :)
