Last season, the drama on Castle wasn't all on the screen.

The show's renewal was left up in the air as contract negotiations with Nathan Fillion, Stana Katic and the rest of the cast went down to the wire. (The show's season finale even felt very much like a series finale.)

However, the show is back — with a new team of showrunners and a couple of new series regulars that hope to shake up the long-running procedural. Check out the links below to see what you can expect this season:
