We’d heard the rumors, we set our DVRs in anticipation, and we were rewarded: in the opening sequence of last night’s Halloween-themed episode of Castle, Nathan Fillion’s Richard Castle broke out his “space cowboy” costume (aka Firefly‘s Captain Malcolm Reynolds) and had some fun. Until his daughter brought him back to earth in a way only teenagers can.

Watch the entire episode on Hulu and watch for the Buffy reference.
