The episode, directed by "Star Trek: The Next Generation" legend Jonathan Frakes, was set at a sci-fi convention, and featured a "Firefly"-style show called "Nebula-9."
“They were canceled over a decade ago. After 12 episodes, which was 12 episodes too many," Castle explained to Beckett.
“I thought you would be a fan," she admitted.
“I’m a fan of good sci-fi. ‘Star Trek,’ ‘Battlestar,’ that Joss Whedon show, but ‘Nebula-9?’ No, it’s all phony melodrama and lifeless acting," our hero proclaimed, much to the joy of the Browncoats in the audience.
"Castle" airs every Monday at 10 p.m. ET on ABC.
