Character mistake: When Squad 51 is dispatched to the fighting couple the first time timeout is 10:12, and the second call to that house timeout is 12:37. When Roy and John are there the first time, it's for no more than five minutes. Then when they're there the second time, Roy says "Please folks, we just went through this less than an hour ago," though it was over two hours when they left the fighting couple the first time.
Revealing mistake: After the two drivers from the traffic accident walk off holding hands, and Johnny tells Roy what happened with Barbara, while Roy explains "body-language" to Johnny, we can see the white tape with "Kevin" inside Roy's helmet.
Roy: I think you're on some sort of an ego trip, Ed. And in my book that makes you a very dangerous character. Ed: [Laughs.] Ego trip, huh? Well, I didn't realize that psychiatry was part of the paramedic's training. Roy: Oh that's good, Ed, you be funny. But that isn't gonna change anything. You wanna know what I figure? Well, I figure when you were working in Vietnam, it was rough. So rough you started playing over your head. And you were making it, you were doing real good. Considering it was a combat situation. And pretty soon you started getting all blown up about how Ed Marlowe is just as good as the real doctors. And you've been living on that ever since. And the trouble is, Ed, you are good. Except for two little problems. You can't quit competing with real doctors. And you can't face being wrong. You see, those people we treat out there, I mean the people we work for, the people who pay for this whole operation, they're real people, Ed, with real problems. And they have a right to expect more than just being used by you for some sort of trip. [Completely exasperated.] I guess what I'm trying to say to you, Ed, is that in my book you're just plain unprofessional. [Ed walks out.] John: Do you think it did any good? Roy: Do you?
Trivia: It's in this episode that the Heimlich Maneuver is used for the first time by the paramedics. At the USC game, when a guy is choking on a hot dog, John and Roy are called, and John uses the Heimlich. Up until season 6 we've seen the guys use other methods, such as the ChokeSaver which look like huge white tweezers, to remove obstructions in an airway, as seen in 4x9, "Foreign Trade."
Answer: It is standard practice to wet down driveways so that they stand out in a long shot.
