Title The Lives of Others
Two-Sentence Summary After Castle injures his knee during a ski trip with Beckett, he’s confined to his loft while the rest of the 12th precinct crew investigates the murder of an IRS agent. However, Castle’s boredom is soon abated with the help of a pair of binoculars and a possible murder across the street, which may or may not have the makings of the best birthday ever for the mystery novelist.
Favorite Lines
Castle: How many murders do you think we’ve solved since we met?
Beckett: I don’t know…Maybe a hundred or so?
Castle: A hundred? Here’s to a hundred more.
My Thoughts When looking at my list of favorite Castle episodes, it became clear to me that my tastes tend to favor the more dramatic fare this show offers up from time to time. However, that doesn’t mean I don’t also love Castle when it’s being fun and funny. I simply like a little substance with my silliness, and that’s the reason I completely adored “The Lives of Others.” It was the perfect way to celebrate 100 episodes of Castle by celebrating what this show does better than any other: effortlessly weaving a web of mystery, comedy, and romance with the help of sharp writing and great performances.
As some of you know, I’m a big fan of Castle’s “genre episodes” (“Heroes and Villains,” “Undead Again,” “The Final Frontier,” etc.), so, of course, I was already predisposed to love this little Alfred Hitchcock tribute. Throughout the episode, I found myself smiling at the nods to Rear Window (especially Stana Katic in that stunning Grace-Kelly-esque dress). Andrew Marlowe and Terri Miller did a fantastic job writing an episode that was a beautiful homage to a classic mystery story while twisting it in a way that was uniquely Castle in its quirky setup and romantic payoff.
Like most of the 99 episodes that came before it, “The Lives of Others” benefitted heavily from Nathan Fillion’s charisma. Ultimately, this episode was a love letter to Richard Castle, and it worked because it reminded us over and over again of why this character is deserving of not one but 100 love letters. Fillion got to show so many facets of Castle’s personality in this episode: his adorable-yet-annoying childishness (whining about when Beckett was going to bring him dinner); his playful sense of fun (The whole bit with the toy helicopter was some hilarious work from Fillion.); and his determination to find the true story behind everything (I loved that his inability to give up on this murder harkened back to his inability to give up on the murder in the pilot.).
One of the things I love most about Castle is the way these characters have grown over 100 episodes while still retaining a true sense of who they were in the pilot. It’s only because we—and the characters—know Castle so well that we’re able to appreciate the twist in this episode for the true joy that it was. Castle is the kind of man who would love nothing more than a murder to solve for his birthday. (In fact, he specifically told Beckett that on Valentine’s Day, which I thought was a cute little thing to bring back.) And Beckett is the kind of woman who understands him enough to get him exactly what he wants. I love when you can feel the sense of history between two characters, and never have I felt that as strongly as I felt it between Castle and Beckett in this episode.
