New "Castle" season 7 spoilers are here!

Previous reports conclude that Rick Castle is well and alive after his unfortunate car accident in the finale of season 6. Most speculate that Bracken and 3XK have something to do with the crime.

However, as TV Guide reported, Bracken and 3XK are not the ones behind the accident. If for anything, the final scenes of season 6 was used to introduce a new mythology in season 7.

Some "Castle" season 7 spoilers suggest that the new mythology involves Castle's secrets and some details of his past life waiting to be exposed. David Amman in his interview with TV Guide further explained the new mythology.

"The mythology we're getting into is going to go past all that [Bracken and 3XK theories] into some new territory." He further added that the speculations about Bracken and 3XK are valid, but reiterated that Castle season 7 will not be opening with that premise.

Of course, all eyes will be on Beckett and how she will take Castle's "secrets." Amman shared, "Things that are going to come to light that are going to be unsettling for Beckett. I don't think what happened to Castle is going to disrupt the trajectory of that relationship, at least not in the long term."

Amann has also shared to TV Line that they have been preparing "a really fun episode" in the upcoming season, and it will most likely be one of the first four episodes. According to Amman, the episode "deals with what seems to be an invisible killer -- and the characters take a lot of pleasure in that."

"Castle" Season 7 is slated for a September 29, 2014 premiere.
