“Don’t be worried,” he said with a smile while stopping by TVLine’s Comic-Con interview suite at the Hard Rock Hotel.

Fillion and his Firefly co-star Alan Tudyk were there to talk about their latest project, Con Man — a separate post on that project will be up later — but the actor took a moment to answer Michael Ausiello’s queries about what the Castle‘s regime change might mean for Rick and Kate.

“In order for a show to continue and to move forward, things have to change,” he said. “And things have changed, every year, for these two.”
