Some Caskett scoop:
- "The Final Frontier" is NOT a filler episode. I cannot stress this enough. You will be very pleased with the amount of Castle and Beckett moments.
- Beckett's an unashamed Nebula 9 fangirl, but don't make fun, because the reveal of KB's geeky, cosplaying past in college paves the way for a great Caskett moment later in the episode that peels another layer off the Beckett onion.
- According to Beckett, Castle's such a big fan of a certain "Star Wars" character that he keeps a life-sized version of him in his bathroom.
- Castle has a bit of a scare during the investigation, which leads to an interesting chat between he and Beckett about his future plans. Let's just say he wants to keep certain options open.
- One of my favorite exchanges between the pair: "In your dreams." / "Look at my life. My dreams come true."
And lastly, you may have read about the final scene of the episode that Jonathan Frakes teased will take Castle and Beckett's relationship to another level. I'll go one step further and say that that final scene? It's going to knock you guys off your feet. Trust me. It was nothing expected.
