|Air date||April 11th, 2014|
|Written by||David Wolkove (Story), Steven Lilien & Bryan Wynbrandt (Teleplay)|
|Directed by||Maja Vrvilo|
A bad tip leaves an abandoned building in ruins, Steve and Danny struggling to survive and the rest of the H50 team racing against the clock to save their trapped colleagues before it's too late.
- Danny and Steve talking about Danny's working with Nurse Ratched was a reference to the 1975 book: One Flew Over the Cuckoo's Nest
- Danny Williams: How does this not end with both of us dying? You're gonna blow something up?
- Steve McGarrett: Called a direction charge. Sends explosive energy in one direction. Anything that's behind it, theoretically, is reasonably safe.
- Danny Williams: It's reasonably... nothing of what you just said sounds reasonable.
- Danny Williams: (Steve is about to cause an explosion that he hopes will create an opening for them to escape through) Hold on. Before we do this, I just want you to know one thing.
- Steve McGarrett: What?
- Danny Williams: Whatever happens, I really, *really*... from the bottom of my heart... hate you so much.
- (He laughs and Steve joins him)
- Steve McGarrett: I love you, too, pal.
- This episode is very similar to Season 6 Episode 11 "Under Fire" from Castle. In that episode it's detectives Kevin Ryan and Javier Esposito respectively who are trapped underneath a collapsed building after an explosion. They also try to get attention by banging ironbars on metal pipes. At one point in both episodes the sentence (or a derivative) "They don't feel like it's a rescue anymore, it's a recovery!" is said by someone.
