Jo Danville: It never hurts to have a confession.
Don Flack: That shouldn't be too difficult. Those two aren't exactly brain surgeons. They'll give it up. Hardest part might be keeping their names straight. The white guy's name is Mike Black. They call him White Mike. The black guy's name is Mike White. His street name is Black Mike.
Jo Danville: I'll take Black Mike.
Don Flack: Great. I got Mike Black.
(Jo looks confused)
Don Flack: The white guy. Don't think about it. But trust me, it's right.

Jo Danville: It was... but we both know I'm just keeping the seat warm for you until you come back.
Mac Taylor: I'm not coming back, Jo.

Jo Danville: Michael Francis?
Lindsay Monroe: Another dead end.
Jo Danville: Francis... Francis, Francis. Stockholm Syndrome. In a lot of abduction cases, the victim will actually start to sympathize with his captors.
Lindsay Monroe: Right, especially when they're held a long time.
Jo Danville: And Arthur Francis was Michael's abductor. Michael Reynolds is Michael Francis. He took his kidnapper's last name.

Jo Danville: No other prints to suggest she was being followed.
Don Flack: No... If this was a chase or a blitz attack there'd be signs of a struggle somewhere.
Jo Danville: I don't see it.
Don Flack: Nope. So what, or who was she running from?
Sheldon Hawkes: Ghosts.
[Flack and Jo look at him disbelievingly]

Jo Danville: Not bad enough this guy's killing people but he's shooting them with exploding bullets.

Jo Danville: Okay, what's going on, Mac? I know you better than you think. Something's up. What suddenly compelled you to investigate a robbery at a bodega on Austin and 123rd?
Mac Taylor: I'm the head of the Crime Lab, Jo. I think that more or less entitles me to re-evaluate any case I want, whenever I want.
Jo Danville: Fine. I have no problem with that. But I'm your colleague and friend and I think that more or less entitles me to ask why.

Jo Danville: Smug little punk. He got off too easy.
Don Flack: I agree. You should have put him under the dumpster.

Jo Danville: So all this time we've been looking at food trucks we should have been focusing on fine dining.
Mac Taylor: Let's go see if murder is on the menu.

Jo Danville: So from about 8:00 to 11:00, I'm just supposed to take your word for it that you were in your room? And the only person who can account for your whereabouts earlier that day is your girlfriend [starts writing down]
Billy Travers: What are you doing?
Jo Danville: Math. Because you're not man enough to admit what you did. Now I gotta do Math. I hate Math. Half hour by train to get to your parents' place. 25 minutes to stand outside and build the courage to kill them. Another 40 minutes inside to do the deed and change your clothes. 15 minutes to puke and then find a place to ditch the bloody clothes. Another half hour to travel to your room (she sums up) Five... ten... carry one... two hours and 20 minutes, give or take. Plenty of time for you to commit the murder and get back to your room.

Jo Danville: Sounds like the punch line to a bad joke, professional killer, and ex-con walk into a bar.

Jo Danville: That ring around the blood spot is called skeletonization.
Don Flack: Why don't they just call it a ring?
Jo Danville: Okay, that's it. Forget it. I give up.
Don Flack: Sorry, it would be much more interesting if you guys used smaller words.

Jo Danville: That's a service apron.
Mac Taylor: You know from experience?
Jo Danville: I worked in a burlesque club when I was an undergrad.
Mac Taylor: As a bartender?
Jo Danville: I never said that.

Jo Danville: This place is so creepy. But I guess, funeral home, what else would it be.
Don Flack: How the hell does a funeral home go out of business?
Lindsay Monroe: The owners died four years ago, the left the family business to the only son, Gordon, he closed up shop apparently, but I understand he still lives here.
Sheldon Hawkes: no prints in the dust, no movement in the air.
Jo Danville: Definately doesn't look lived in.
Lindsay Monroe: or died in.

Jo Danville: Torres' death leaves a void at the top of his crew, so I thought I'd look at his replacements might be able to avoid a street war if we can talk to them. So I'm gathering this as I go. Seems, Torres was the face of this crew, but Lisa Brigosa... she's the brains and Rick Devarro is the street muscle. Although, given his penchant for getting arrested, Rick's not too bright.
Mac Taylor: There's one other. Luther Devarro.
Jo Danville: Any relation to Rick?
Mac Taylor: His older brother. Founder of El Pu�o, but more of an advisor at this stage of his career. I helped put him away 15 years ago. He was released last week.
Jo Danville: Gasoline on the fire.
Mac Taylor: It's one thing to be a street guy, another to be smart. But it's dangerous when both those qualities are embodied in one person.

Jo Danville: We've known each other for about a year now, Don. I have never told you this, but I think you're one hell of a detective.
Don Flack: Thanks, Jo.
Jo Danville: You're welcome.
Don Flack: Jury's still out on you, interim boss.
