Castle: You’re alive. Whoa and you’re naked.
Beckett: Castle, turn around!
Castle: You know, your apartment is on fire. Now might not be the best time for modesty.
Castle: Are you in any pain?
Beckett: Well, not nearly as much as you. It’s killing you, isn’t it?
Beckett: Having to wait this long to tell me how you banged down the door.
Castle: You want me to start from the beginning?
Beckett: Does anyone know if insurance pays for dry cleaning?
Scott Dunn: You were supposed to be dead.
Beckett: Well I’m sorry to disappoint you.
Beckett: Okay, do you have a better idea, 'cause I am all out. And if we don’t catch him soon, he’s gonna kill again.
Jordan: You can’t take this personally.
Beckett: The hell I can’t. He just blew up my apartment. I think that’s pretty damn personal.
Beckett: And if you keep quoting Jordan, I am going to turn the radio way up.
Castle: (Singsong) Jealous.
Jordan: Castle, what part of “un-ass” don’t you understand?
Castle: All of it.
Jordan: For future reference, it means, “Get the hell out and don’t take anything.”
Castle: “Un-ass.” Nice. (Whispers and writes down) “Un-ass.”
Jordan: (To Beckett) Is he always like this?
Beckett: Castle has the attention span of a cocker spaniel.
Jordan: Hmm. And the loyalty…the way he follows you around. From what I’ve observed, this unorthodox partnership…works well for you.
Beckett: For now.
Jordan: Is it enough?
Jordan: (Over a microphone) We’re blown. We’re blown. All units, go hot now. (Beckett gets out of the van) Stay in the van. You’re the target. (Beckett slams door shut and scoffs at Jordan)
Castle: Now you know what it’s like for me.
Capt. Montgomery: You’ve been running flat-out for days, you need to go home and get some sleep.
Beckett: Sir, I don’t have a home.
Castle: Yes you do. It’s a secure building with an extra bedroom with people who care about you with a federal detail at the door. It’s the safest place in the city.
Beckett: Thank you Castle, but I couldn’t.
Castle: You can and you will.
Beckett: Well, who would’ve thought that I would be homeless and caseless in one day?
Castle: I’m sure after all you’re a little sorry you let me follow you around.
Beckett: No not this. All the other annoying things that you do, but not this. What about you? Are you sorry you wrote Heat Wave?
Castle: The way I look at it now, if it wasn’t for Nikki Heat this guy would have just gone on killing because he wouldn’t have met anyone smart enough to catch him. I’m speaking of course of Special Agent Shaw.
Castle: Wow, that’s funny every Sunday my mother would have me make her an ice pack and a Bloody Mary.
Martha: (To Beckett) Don’t listen to him. That only happened twice…tops.
Castle: I feel like Princess Leia when the Millenium Falcon escaped the Death Star. It’s too easy.
Beckett: Castle, you and I have known each other long enough for me to know that sometimes your silly theories are right…
Beckett: (Hands Castle her gun) Here.
Castle: You want me to hold it while you tie your shoe?<br.
Beckett: Castle, you’re my only backup.
Scott Dunn: This isn't over, Heat.
Beckett: It's not Heat. It's Beckett. You have the right to remain silent...so shut the hell up.
Beckett: Helluva shot Castle.
Castle: I was aiming for his head!
Ryan: Hey, we're thinking maybe you could talk to Montgomery about finding some room in the budget for those smart boards.
Beckett: Sure. While they're at it, maybe they could buy us Batmobiles.
Esposito: That'd be cool.
Beckett: Our murder boards are just fine.
Esposito: For a caveman.
Jordan: He cares about you, Kate. You may not see it, you may not be ready to but, he does.
Beckett: Yeah, well the situation with Castle is…complicated.
Jordan: (Knowingly) Oh.
Jordan: You are a valuable asset to Detective Beckett's team.
Castle: Well, it would be great if you would call her and remind her of that from time to time.
- This was the highest rated episode for Season 2
- Stana Katic said in an interview with Daemonstv.com that this episode, along with episode 2.13 (Sucker Punch), was one of her favorites from season 2. "I thought that was really fun. It was really great to see how the build up in the first part of it climaxed in the second of the two-parter and all the action stuff was really fun. It got dark a bit and in spite of the darkness there was a tremendous amount of humor injected here and there. I thought it was really, really neat episode and really exciting as a thing to be a part of. Of course we're exploding apartments and things like that. So all of that stuff was a fun to be a part of, doing fight sequences and all of that." 
Full Episode Recap
Picking up where Tick, Tick, Tick… left off, Beckett’s apartment has been blown away. Castle breaks down the door, frantically calling her name. Amazingly, Beckett is alive! She survived the blast by jumping into her tub. And she happened to be naked. With her towels and bath robes in flames, Castle covers her body with his coat (don’t worry, he didn’t look) and they escape the fiery ruins.
The team realizes the killer must have remained in Ben Conrad’s apartment when the FBI showed. Beckett finds a false wall in the closet. Inside are the remains of the real killer’s disguise and duct tape residue that indicates Conrad was being held hostage. Beckett gets a call. It’s the killer. He’s disappointed Nikki Heat survived. This was supposed to be over. Now he’ll have to kill again.
Castle points out that the killer must’ve known Ben Conrad to be able to pose as him. After finding out that Conrad was a Knicks fan, Beckett and Castle discover that he made a friend at a local sports bar. The bartender remembers calling the guy a cab one night. Using FBI technology, Agent Shaw zeroes in on possible suspects in the area. One of the matches, Chris Doherty, was murdered six years ago. The killer assumed his identity.
Beckett’s team and the FBI storm the suspect’s apartment to find a shrine to Beckett/Nikki Heat. Castle skims the pages of a manuscript and realizes the killer was writing a book based on his murders. The FBI sets up a stakeout on the apartment. Defying Shaw’s orders, Beckett leaves the surveillance van when she spots the killer close to her position. She chases him down, but loses him on the subway.
The feds use facial recognition software to get an ID on our killer, whose name is Scott Dunn. Before Beckett can mobilize her team, Shaw takes her off the case. Needless to say, Beckett is upset. She can’t work and can’t go home. Well, she can’t go to her home. Castle, however, offers her his. He says, “It’s a secured building with an extra bedroom and people who care about you.”
Back at Castle’s place, he and Beckett chat about the case in their usual bantering way. Beckett asks Castle if he’s sorry he wrote Heat Wave. Castle says, “The way I look at it now, if it wasn’t for Nikki Heat, this guy would have just gone on killing because he wouldn’t have met anyone smart enough to catch him. I’m speaking, of course, about Special Agent Shaw.” Case or no case, some things never change.
Speaking of Agent Shaw…she’s in trouble. Dunn hides out in her car and kidnaps her at gunpoint. He wants Beckett to meet him alone or Shaw dies. When Beckett asks for proof that Shaw is still alive, Dunn emails her a video of him holding her captive. Looks like Beckett’s back on the case.
Using clues in the video, they are able to triangulate the location to an abandoned building. Castle thinks this is too easy. Once the FBI agents are gone, Beckett asks Castle what’s bugging him. He says this isn’t the way he’d write the scene. He’d make the FBI swarm the building and then blow it up. And he’d be watching it all from a building nearby. Beckett hands Castle her backup pistol and tells him to follow her. He’s her only backup.
In a neighboring warehouse, Beckett spots Shaw bound to a chair with tape across her mouth. Beckett confronts Dunn, bluffing that the FBI agents are not in the other building. That means Nikki Heat won. Dunn panics and throws the detonator-phone at Beckett, fleeing deeper into the warehouse. Castle tries to untie Shaw, who urges him to go help his partner.
Beckett gives chase, but Dunn gets the drop on her. Castle arrives to find Dunn standing over Beckett, a gun pointed at her head. BANG! Castle fires, hitting Dunn’s gun and knocking it out of his hand. Dunn dives for the firearm, but Shaw steps on his hand, a gun aimed at his head. Beckett cuffs Dunn, who says, “This isn’t over, Heat.” Our favorite homicide corrects him by saying, “It’s not Heat. It’s Beckett.”
With the killer apprehended, the FBI takes its expensive toys and bugs out of the precinct. Shaw and Beckett say goodbye, each having grown to respect the other. Regarding her partnership with Castle, Shaw says, “He cares about you, Kate. You may not see it. You may not be ready to, but he does.” Hey, we didn’t need an ace FBI profiler to tell us that one.
