Secrets can kill!

It's been weeks since De Nogaret revealed to King Philip that Landry and Queen Joan were having a secret affair on Knightfall -- but now Philip is finally ready to take action. 

Only ET has an exclusive clip of Wednesday's season finale, in which Philip directs his rage at Landry after Joan tries to escape with their unborn child, and orders De Nogaret to destroy him. 

"Can you do it outside Paris, quietly?" Philip asks. 

"Of course. He will come through the forest of Versailles. I can dispatch a party of red knights to intercept him there," De Nogaret replies. 

See the full clip in the video player above. 

ET spoke with Tom Cullen before Knightfall's series premiere, where he promised that fans wouldn't be disappointed by the show's season finale. 

"The battle scenes all the way to the really amazing, delicate relationships that play out in the show, [form] a really rich world full of conflict and great politics," he said. "If you last through the 10 episodes, it's going to be a real high-octane journey. I hope that people enjoy it as much as we enjoyed making it." 

The season finale of Knightfall airs Wednesday, Feb. 7 at 10 p.m. ET/PT on History.
