- Luke Girardi: You've got the world's largest blind spot, you know that? One minute, y - you discern an oblique pattern that's invisible to mere mortals, the next, you can't even see a conclusive certainty that's staring you in the face.
- Will Girardi: I have no idea what you just said.
- Luke Girardi: You always say that I got my brain from Mom. That's not true. I get it from you.
- Will Girardi: Then why didn't I understand what you said?
- Joan: [referring to her new friend, Casper, a homeless inner-city kid who suddenly left without saying goodbye] What a cop-out! You get me all wrapped up in her life, and now you're not even going to tell me what happened to her?
- Double Dutch Girl: [speaking as God] The connection you and Casper had - you think that's gone just because she went away? Is your connection with Adam gone just because he's with Iris? Real connections - they can't be broken by time or space.
- Joan: I wanted to help her. I - I wanted to get her a place, get her dad a job.
- Double Dutch Girl: You can't fix everything, Joan.
- Joan: She's my friend. I want to know what's going to happen to her.
- Double Dutch Girl: I know you do. But, sometimes, it's enough to plant the seed, walk away, and let the flower grow on its own.
- Dr. Henry Sendak: Will, look, we had a deal. Now, Thursday is Bring Your Kid to Work Day, and you haven't signed up yet.
- Will Girardi: You think I want my kids to see me shuffling papers? I'm a cop, Henry. If I had my piece back, could work the field...
- Dr. Henry Sendak: Will, what you're going through here, post-traumatic stress, it comes with the job. It is nothing to be ashamed of. And being able to let your family go through that with you, even then kids, it's-it's the best medicine.
- Will Girardi: So this is a test, right? To see how solid I am.
- Dr. Henry Sendak: You pulled your gun on a four year old. You want to go back out on the street worried that you could melt down again?
- Joan: Mom, whatever you did to Adam today, he's, like, totally catatonic, so I hope that's what you were going for.
- Helen Girardi: Yeah, well, my teaching methods are not open for discussion.
- Will Girardi: I smell garlic.
- Joan: Before you launch into the embarrassing lecture on the health benefits of garlic, this is my friend Casper, and she doesn't care.
- Will Girardi: Nice to meet you. It is a natural antibiotic, you know.
- Karen Casper: It also lowers blood pressure.
- Will Girardi: I love this kid.
- Luke Girardi: These are all cold cases?
- Will Girardi: How do you know about those?
- Luke Girardi: I asked mom what you were working on.
- Will Girardi: You did?
- Luke Girardi: They're all unsolved? I mean, there's hundreds.
- Will Girardi: 90% dead ends. I leaf through them on a wing and a prayer.
- Will Girardi: Reggie runs the CSI lab. Things that spin and blink and whir. You'd be in heaven.
- Reggie Wommick: We just installed a new processor for DNA analysis. It's killer.
- Luke Girardi: An automated genetic analyzer? They use capillary eletrophoresis, right?
- Reggie Wommick: Are you sure he's your kid? I mean, I can run your DNA.
- Will Girardi: He gets the brains from his mom's side.
- Luke Girardi: I mean, if you're embarrassed to be with me, why did you even ask me to come?
- Will Girardi: [he storms upstairs] I'm not embarrassed to... Luke!
- Helen Girardi: What happened?
- Will Girardi: I can't really say.
- Joan: [scoffing] Oh! How come he can get away with that?
- Helen Girardi: 'Cause he's confused. You're lying.
- Will Girardi: Do I want to know about this?
- Helen Girardi: Oh, you will.
- Luke Girardi: I became a scientist because of you, because you're a detective.
- Will Girardi: You did?
- Luke Girardi: We're the same. We both solve puzzles in a universe where there is no certainty, only probability and possibility.
- Will Girardi: Well, I-I never... thought of it like that.
- Luke Girardi: Only I live in my head. You're in the world changing people's lives. Like today. How could you think I wouldn't want to see that?
- Joan: Remember when we were just losers? Sub-defectives with no hope of friends or a social life?
- Grace Polk: Something change that I don't know about?
- Joan: Uh, yeah. Adam's all "Ooh!" about Iris, and Luke, who I can always count on to be more pathetic than me, has hooked up with Glynis, shining a big spotlight on what a total washout I am. If I was a Viking, they'd put me on a flaming raft and send me out to sea.
- Grace Polk: You did the history reading.
- Joan: That's how desperate I am.
- Grace Polk: That thing with Rove is not gonna last.
- Joan: Oh, why? Are his lips gonna fall off from making out too much?
- Grace Polk: I was trying to be positive. It's not me. Rove and Iris are perfect for each other. They'll probably have a house full of emotionally damaged babies by senior year.
- Joan: So where do I fit in?
- Grace Polk: Mmm, you don't. Isn't that how this whole conversation got started?
