Fellow One Life To Live alum Chris McKeena will be guest starring in Castle’s November Comic-Con themed episode, “The Final Frontier”. This episode will pay a certain amount of homeage to Fillion’s beloved role as Captain Mal Reynolds on Firefly. McKeena will play a “Nebula 9″ superman named Simon Wesport, who may have been romantically involved with the victim.
In other Castle news episode 9 will be called “Secret Santa”. The episode will center around the death of Edmund Smith, who was a Santa at a Santa school. On a merrier note, Castle and Beckett will have a very romantic scene.
