Question: Any word on who will be writing Castle‘s season premiere? —Ben

Ausiello: The good news:Newly coronated showrunner David Amann is penning the Season 7 opener. The even better news: Rob Bowman is directing. And now, the provocative news: Castle will return with a two-parter, and to that end is casting the guest-starring role of “Henry,” a highly intelligent yet unassuming gent who’s deft at blending into a crowd. (A spook-y nemesis of Jackson Hunt’s? 3XK with a new face c/o Dr. Niemann? Discuss.) Also being guest-cast for the premiere are a Hamptons police sergeant, a doctor, a shrink and… a Coast Guard captain?!
