Revealing mistake: Season 4, episode 21: "Dead Air". At the start, when Horatio looks at the call details, it very clearly reads "no sim card inserted" at the top of the screen. Quite hard for the accidental recipient of the call to have a working phone without a sim card...

1 mistake in Dead Air
Horatio Caine: Mac, I have a sixteen year old girl who is suddenly without both parents. I have promised her peace of mind.
Mac Taylor: I got an officer's widow who'd like some answers.
Mac Taylor: We got a deal.
Tinder Box - S1-E22
Trivia: Because the episode 'Tinder Box' closely resembled (and was likely based on) the fire at a nightclub in Rhode Island that killed 100 people, the local CBS affiliate decided not to air the episode so soon after the event.
Question: In one episode, Delko is seen driving away from a deal gone wrong and Delko's informant is seen with him. Delko says that he doesn't feel good and passes out from blood loss causing the informant to call for 911. What episode is this and why was his informant arrested?
