Still reeling from the news that Stana Katic is leaving Castle [1]? Not only is it a bummer that she won't be on the show anymore, but it's also borderline anxiety-provoking to think about how the show will continue without Beckett. Her costar Nathan Fillion has responded to the news, and if you're a fan of Caskett, it might bring tears to your eyes.
