Goof: When Beckett first walks up to Royce's dead body, his eyes are open, but when she kneels down to stroke his temple, his eyes are closed.
Goof: After interrogating Reggie, Beckett is seen to undo the first button of her shirt but in the next shot, when she is handing her gun, her shirt is buttoned all the way up.
4th time a Pearl Jam song is used on an episode ("Off He Goes", "Unthought Known", "Just Breath" and "The End") in the show.
Castle drives a Ferrari California (2008'-11').
Montgomery: Hey, you heard from Beckett?
Esposito: No, sir.
Ryan : Yeah, me neither.
Montgomery: She's not answering her cell?
Esposito: Maybe she's airborne
Ryan : Uh-huh. Yeah, that would explain her phone being turned off.
Montgomery: (to Esposito) You know I am trying to decide who is the worse liar, (nods at Ryan) him or you.
(Esposito nods at Ryan as in "him")
Montgomery: (to both of them) Go find Violet Young. Help Beckett put this thing to bed, all right?
Royce: (on the letter) And now for the hard part, kid. It's clear that you and Castle have something real, and you're fighting it. But trust me, putting the job ahead of your heart is a mistake. Risking our hearts is why we're alive. The last thing you want is to look back on your life and wonder, if only...
Beckett: My name is detective Kate Beckett, NYPD. Michael Royce was my friend. You shot him and you left him in an alley like a piece of garbage. Consider this poetic justice.
Ganz: He said something about hell raining down on me. I never imagined hell looked like you.
Beckett: (talking about Castle's car) Is this what you call under the radar?
Castle: In L.A. this baby fits right in. So what's our first stop?
Beckett: My hotel, is on Ventura Boulevard.
Castle: That's all the way in the valley. How are we supposed to work together if you are an hour away?
Beckett: Castle we weren't suppose to work together at all.
Castle: Okay look, the studio comped me a two-bedroom, four star suite. You just stay with me.
Beckett: Ha, yeah right.
Castle: What? You'll have your own room.
Beckett: Uh no, I'm not staying with you.
Castle: Ahh, worried you can't control yourself when we're alone?
Beckett: Actually it's not me that I'm worried about.
Castle: I assure you, my intentions are pure.
Captain Montgomery: What you can do is get your ass on the next plane out.
Castle: Uh, we have a dinner reservation at Spago. Is the morning okay?
Captain Montgomery: Oh, this is all a big joke to you, isn't it, Castle? But when Beckett is working mall security, I guess following her around isn't gonna have quite the same allure.
Castle: Would you like to choose your room?
Beckett: No, I'd like to start the investigation.
Castle: We haven't even ordered room service yet.
Beckett: Castle, I'm not here for room service. I'm here for justice.
Castle: Wow. In L.A. for all of a minute, and already she's spouting cheesy movie dialogue. Must be something in the air.
Beckett: You cannot be a part of what I'm gonna do out there.
Castle: I thought you were on vacation.
Beckett: Castle... It is one thing for you to follow me when we're in New York, but I am not a cop in L.A. I don't have any authority or backup.
Castle: I'll be your backup. Besides, going rogue is kind of my specialty.
Beckett: Yeah, but subtlety isn't. I'm not gonna get rid of you, am I?
Esposito: (on the phone with Beckett) What's up girl? How's the weather in your world?
Beckett: Sunny with a chance of ass kicking.
Castle: You know what I thought when I first met you? That you were a mystery that I was never gonna solve. Even now, after spending all this time with you, I'm still amazed by the depths of your strength, your heart and your hotness.
Beckett: You're not so bad yourself Castle.

The episode title is a take on the 1985 movie To Live and Die in L.A. which is about a bold Secret Service agent who will stop at nothing to hunt down the counterfeiter who killed his partner.
At the Zenith Studios in L.A. while Beckett is talking to Castle along with the actors that are playing Ryan and Esposito, a couple of scenes display other actors in the immediate background. You can see a pirate looking very much like Captain Jack Sparrow from the movie "Pirates of the Caribbean" and a couple of nuns with assault rifles (AK-47's) looking like the costumes from the movie "The Town".
