'Castle' Decision Incoming as Nathan Fillion Locks Down Season 9

As for those expected to return alongside Fillion, Castle Season 9 would also feature Molly Quinn, Susan Sullivan, Jon Huertas and Seamus Dever, along with Season 8 addition Toks Olagundoye.

A few weeks back, Castle fans were agape at the thought of a ninth season without series star Stana Katic, as well the circus and rumors and cast reactions that flew since.

Nathan Fillion hadn’t signed for Season 9 at the time, but has now reportedly been secured, while ABC is set to make a decision on the series before the weekend.
