The fifth season centers on two officers Castle and Beckett who finally started on a romantic journey with each other. Whereas, they intend to make this a secret to their team leader, Captain Victoria Gates, and they can't also afford to let it known among their counterparts.
The premiere had pretty much everything us Castle fans have grown to love: humor, mystery, suspense and a detective/writer pair that we can't help but adore.
Instead of getting caught up in it, you patiently wait for it to resolve itself, in the hopes that when it's all over, you can figure out what happened.
