Hey, guys. Sorry for the late post, I haven’t had access to the site these days, I have no idea why. I have already watched Castle Season 4 Episode 16, “Linchpin”. This episode continues to fill with excitement. This time, Detective Kate Beckett (Stana Katic) and Writer Richard Castle (Nathan Fillion) finds out that one of their very own in the CIA betrays the country and tries to start a World War 3. This mission is kept from lots of people, everyone in District 12, including Detective Javier Esposito (Jon Huertas), Detective Kevin Ryan (Seamus Dever), Captain Victoria Gates, also known as Iron Gates (Penny Johnson), Medical Examiner Lanie Perish (Tamala Jones), Intern Medical Examiner Alexis Castle (Molly C. Quinn), and also Richard Castle’s Mother Martha Rogers (Susan Sullivan). This episode is highly recommended to watch, but will need to watch Castle Season 4 Episode 15, “Pandora” to understand the whole story, since the two episodes are connected. I hope that for you all that have watched it, enjoyed it, and those who haven’t, should go download it or watch it online on www.sidereel.com. Enjoy!
