Jigsaw kidnaps a doctor to keep him alive while he watches his new apprentice put an unlucky citizen through a brutal test.

Dr. Lynn Denlon: [after drilling holes into his skull non-anesthetized] John, how're you doing?
Jigsaw: Never better.
[from trailer]
Jigsaw: Hello, America. Do you wanna play a game?
Jeff: I forgive you.
Eric Matthews: You're not Jigsaw, bitch!
Amanda: [to Lynn] Let me give you the simple version. You will keep him alive, whatever it takes. No excuses, no equivocations.
[whispers]
Amanda: No crying.
Danica: I didn't do anything to you!
Jeff: That's exactly it, you didn't do anything.
Jeff: [while the Judge is screaming for his life] Shut the fuck up...
Jigsaw: Death is a surprise party.
Jigsaw: [after Amanda gets shot] Amanda... It's OK. This was your test. Your game. I was testing you. I took you in. I selected you for the honor of carrying on my life's work. But you didn't. You didn't test anyone's will to live. Instead you took away their only chance. Your games were unwinnable, your subjects merely victims. In my desperation I decided to give you one last chance. So I put everything in place. You didn't know that Lynn and Jeff were husband and wife. I had to keep that from you for the purposes of my game. I had to leave out the ruined marriage, the cheating wife, the vengeful husband, the neglected daughter and I let you make your own choices. I wanted you to succeed... You couldn't.
[Amanda begins to collapse and die]
Jigsaw: God...
[Amanda finally dies]
Jigsaw: Game over.
Amanda: I'm sorry. I know it's hard to concentrate when you're surrounded by so many things you could kill me with. Like this axe I saw you looking at.
[holds the axe out to Lynn]
Amanda: Take it. Please, it's yours. Come on. I go for the neck, but I'm not the brain surgeon. Just do it quietly so John doesn't hear me die. Otherwise, he is likely to get upset, rip off his heart rate monitor - boom! Then, you just have to find the sensor and disarm it so you can walk more than thirty feet out that door without the collar detonating. Or, you could try and take the collar off yourself. But that could be tricky. The slightest knock in the wrong place could trigger it. I should know. I built it.
Amanda: He made it through the freezer room. He tried to save her.
[starts crying]
Jigsaw: There are some things I need you to do for me. In my desk. An envelope with your name on it.
Amanda: [referring to Lynn] She's going to do a procedure on you.
Jigsaw: Yeah?
Amanda: To relieve the pressure on your brain.
Jigsaw: Yeah.
Amanda: Help with the headaches.
[pauses]
Amanda: I can't do this!
[leans back in the chair and cries harder]
Jigsaw: Amanda, you can. You can! You're stronger now. And I believe in you.
Amanda: You chose her because she's the best, right?
Jigsaw: That's one reason I chose her.
Jigsaw: And what about the other test subjects?
Amanda: What about 'em?
Jigsaw: Is that how you felt about them? Is that how you felt about Eric Matthews?
Amanda: Eric Matthews? I'll tell you how I felt about Eric Matthews. Eric Matthews learned NOTHING from your test. He was the SAME person he was and he arrested me, and he framed me when he took me DOWN!
[flashback]
Eric Matthews: Where is he, you junkie bitch? You're not Jigsaw, bitch!
Judge Halden: Jeff, just standing there, you're accomplice to murder. Are you a murderer Jeff?
Jeff: I've been wanting to kill him for two years.
[Timothy Young starts screaming in agony]
Jeff: Yeah. Maybe I am.
Jigsaw: Matrimony has always fascinated me. Husbands barely able to look at their wives, wives on their backs in hotel rooms with perfect strangers; able to bear children to bear children only to neglect them; until death do us part indeed.
Jigsaw: Amanda, do not be afraid. Your life has just begun.
Tim: What the fuck are you doing?
Jeff: [Presses play on tape recorder]
Jigsaw: Hello, Jeff. If you are listening to this, that means that the confrontation you so long dreamed of... is finally unfolding. In your head, he is a cipher. A symbol of your life changing. A symbol of death. I present him to you now, as a simple human being. His name is Timothy Young. He's 27 years old. A medical student with a mother and a father, just like you. A man who's life also changed the day your son died.
[Flashback]
Jigsaw: That day he made a terrible mistake. You believed he didn't pay for that mistake. And now is your chance to make him pay. The device Timothy is strapped to is... my personal favorite. I call it "The Rack".
Tim: [Screams]
Jigsaw: The human body is a miraculous creation. Ever wonder how far an arm can twist? This device is going to start twisting. There is a chance he might live though, with your help. To your right is a box. At the back of the box, is a key. It is tied to the trigger of a shotgun. The question you'll have to ask yourself, is this. Are you willing...
Tim: Have mercy!
Jigsaw: ...To take a bullet for the man who killed your son? Does "do on to others as you would have them do on to you" apply here, Jeff? Make your choice.
[device begins to twist]
Amanda: So?
Dr. Lynn Denlon: My twenty second analysis without any medical equipment is that his brain is herniating.
Amanda: [sarcastically] Oh.
Dr. Lynn Denlon: He needs to go to the hospital and have an operation to decompress his brain.
Amanda: [whispers] Come here. No, really, come here. Come here.
Dr. Lynn Denlon: No.
Amanda: [whispers] Let me ask you something.
[grabs Lynn by the hair]
Amanda: Did I bring John to you? Or did I bring your self-centered ass to him?
[whispers]
Amanda: Now you better start fucking paying attention. No one's going to any hospital.
[forcibly lets Lynn go]
Dr. Lynn Denlon: I can't perform miracles. You're giving him painkillers - for a tumor like this he needs steroids, prednisones.
Amanda: [sarcastically] Oh, good, yeah.
[yells]
Amanda: Maybe we could try some corticosteroids, you know, like dexamethasone. Why don't you fucking tell me something that I don't know! Stupid cunt!
Judge Halden: Don't become what he is! Don't become a murderer!
Rigg: What I don't understand is, how the hell could Jigsaw do all of this? He was damn near on his death bed the last time we saw him.
Kerry: I'm not so sure he did.
Jeff: I forgive him!
Jigsaw: Hello, Jeff. I made this tape as an insurance policy, if you will. And if you're listening to it, then it's time to collect. I was your final test of forgiveness and if you're listening to this, then you've failed. Now you must pay the price. The price for living for nothing but vengeance. Now I will give you something to live for. I told you that you couldn't kill me, Jeff, but I didn't tell you why. The answer is simple. I am the person responsible for the loss of your child. I am the only person who knows where your daughter is. She only has a limited supply of air, Jeff, and if you want to get her back, you'll have to play a game.
Jeff: No!
Dr. Lynn Denlon: Jeff!
[Lynn's collar detonates]
[first lines]
Amanda: Game over.
Eric Matthews: I'll fucking kill you! You fucking bitch! You fucking bitch! I'll fucking kill you!
[screams hopelessly]
Jigsaw: If you make it through this, Lynn, you're going to thank me one day just as Amanda did.
Judge Halden: I'm so sorry about your son, Jeff. But let me tell you something that I know for sure. No sentence that I gave him, not 500 years, not even death. Nothing will take your pain away. And vengeance doesn't solve anything. It only makes the pain greater, Jeff.
Amanda: Are you gonna behave?
Kerry: If the aim of Jigsaw's game was to get out before the bomb went off then why was the door welded shut?
Dr. Lynn Denlon: What do you want?
Jigsaw: I wanna play a game.
Jigsaw: I'm sorry but is all this crude medical equipment around you causing you to believe that you're still inside a hospital?
Dr. Lynn Denlon: No...
Jigsaw: Then why are you speaking to me on the graduate school medical jargon? LOOK AT ME!
Jigsaw: Do you remember me?
Jigsaw: [after Amanda attacks Lynn] I apologize for her behavior. She swims in my sea. In the end she will be the closest I've ever gone to a connection. To being understood. But her emotion is also her weakness.
Jigsaw: Never been better.
Amanda: So, do you have everything you need?
Dr. Lynn Denlon: I have the instruments to cut someone open. I don't have the tools to save a life.
Amanda: [Amanda looks down at the Jawsplitter] You'd be surprised what tools can save a life.
[Amanda picks up the Jawsplitter]
Jigsaw: Don't you think it would be wise to engage me in conversation for your own sake? I asked you to tell me about your husband.
Dr. Lynn Denlon: It's like we're strangers now.
Jigsaw: And?
Dr. Lynn Denlon: The last time I saw him we were so disconnected. But now I'd give anything in the world to see my husband.
[cries]
Jigsaw: It's time to start our game.
Dr. Lynn Denlon: Who are you? Who are you? WHAT IS THIS? WHAT ARE YOU DOING?
Amanda: [casually threatens Lynn with a knife] Are you gonna behave?
Dr. Lynn Denlon: Please, let me go. I saved your life!
Jigsaw: Maybe my life isn't the one you are saving, after all.
Amanda: Right fucking here!
Amanda: Yeah, that's right. I'm a murderer.
Amanda: She doesn't deserve to go free!
Jigsaw: I have tried to help you, Amanda.
Amanda: Then help me! Fix me! Fix me motherfucker! I'm standing right here!
Jigsaw: Live or die, Jeff. Make your choice.
Dr. Lynn Denlon: I don't know what you think you know, but my marriage has survived more suffering than someone like you could ever grasp.
Jigsaw: Suffering? You haven't seen anything yet. Someone like me, who am I?
Dr. Lynn Denlon: A monster. A murderer.
Jigsaw: I don't condone murder and I despise murderers.
Troy: Help!
Jigsaw: Hello, Troy. I want to play a game. This game will take place in a room not much bigger than the room you spent most of your life in. A prison cell. Despite all of the advantages and privileges that you were given at birth, you have returned to prison again and again. More comfortable in chains than you are in freedom. Tonight, we will see how far you are willing to go to break those chains once and for all. Live or die, Troy. Make your choice.
Deborah: [to Lynn in the Emergency Room] Look, if you've got something on your mind go upstairs to psych. Just don't bring it in here. We don't have any seconds to spare, Lynn! The woman standing in front of me had to be dragged from the locker room to put a chest tube in a trauma patient. Lynn Denlon should have been the first one there.
Dr. Lynn Denlon: You're asking me to do the impossible.
Amanda: I'm not asking you.
[referring to Jigsaw]
Amanda: He is.
Amanda: He's completed the third test.
Jigsaw: Congratulations Lynn, you're free to go.
Amanda: Yeah, but he's not all the way out yet.
[shakes her head]
Jigsaw: Undo her collar, Amanda, and let her go.
Amanda: No, he's not finished. He's not all the way.
Jigsaw: Amanda, Lynn is more important than you know. Unlock her collar and let her go.
Amanda: [whispering] I said no.
[caulks a handgun]
Jigsaw: Amanda, there are rules.
Amanda: [yelling] I said no!
Kerry: [referring to Eric] I really had this feeling it was going to be him.
Rigg: Eric is a missing person case not a homicide case.
Kerry: I've been having nightmares. I see him! I'm never going be able to forgive myself for what happened.
[starts crying]
Rigg: Listen, it's not your fault.
Kerry: It's always somebody's fault, Rigg.
Rigg: But that somebody isn't you. That person is still out there. So put all your anger into finding them and putting them away.
Amanda: He made it through the second test. The judge is alive.
Jigsaw: Faster than I expected.
Dr. Lynn Denlon: [before the surgery] Alright, John, I need you to keep your head to the side and keep still. What's going on here is your brain is pushing against your skull. I'm going to try and relieve the pressure by cutting away a little bit of your skull. It should help you with your headaches and drastically improve your motor skills. Do you understand?
Jigsaw: All too well.
Dr. Lynn Denlon: [injecting medicine] You're going to feel some slight discomfort.
Amanda: Are you going to give him a general anesthetic?
Dr. Lynn Denlon: For a procedure like this the patient needs to be fully alert.
Amanda: Eric Matthews? I'll tell you about Eric Matthews. Eric Matthews learned *nothing* from your test.
Dr. Lynn Denlon: I don't know what you think you know, but my marriage has survived more suffering than someone like you could ever grasp.
Jigsaw: Suffering? You haven't seen anything yet.
Jigsaw: Welcome to your first test, Jeff. For the past three years, you've cursed the name of all those you thought were responsible for the death of your son. You've fantasized those accountable will pay. Well, you'll find a woman in front of you chained in place. This will prevent her from running, much like she did on the day your son was hit. Her name is Danica Scott. She was the only witness present at the scene of your son's untimely demise. If not for her own self absorption and cowardice, she could have brought your son's killer to justice. Now it is you, who has a chance to bring her to justice. You alone can grant her the gift of life before she freezes to death. Behind the pipes on the back wall, you will find the key that will free her and bring you one step closer to the man responsible for the loss of your child. Will you claim the key to save only yourself? Or can you find it within you to save another? Make your choice.
Jeff: [comes into Corbett's room looking for Dylan's stuffed animal] Where is it?
Corbett: What?
Jeff: [sees her holding it] How many times? How many times do I have to tell you before you get it in your head?
Corbett: I just wanted to sleep with something.
Jeff: No, no you just nothing! You don't touch things in Dylan's room! Okay?
Corbett: I'm sorry, daddy.
Jeff: You know I love you, don't you?
Corbett: [nods] Yes.
Jeff: What do you think mommy would say if she saw us like this?
Danica: Please help! Please? I'm so cold. I can't feel my arms.
Jigsaw: Jeff, when the judge presiding over your case sentenced your boy's murderer so lightly, your soul never recovered. Now, you have the power to sentence his soul straight to hell. Or, you could forgive. The key that will free him is hidden inside your son's possessions, possessions you have clung to for far too long. Now if you flip the switch on the incinerator underneath you, a fire will cleanse you of this obsession and destroy them all, leaving only the key remaining. It is also the key that will bring you closer to the man accountable for taking your child. He doesn't have much time, Jeff. Let the game begin.
Jigsaw: Hello, Kerry. I want to play a game. Up until now, you have spent your life among the dead, piecing together their final moments. You're good at this because, you, like them, are also dead. Dead on the inside. You identify more with a cold corpse than you do with a living human. I believe you want to join your true family, indeed your only family... In death. The device you're wearing is hooked into your rib cage. By the time this tape is finished, you will have one minute to find a way out. At the end of that minute... You should know better than anyone, what happens then. There is a single key that will unlock the harness, Kerry. It is right in front of you. All you have to do is reach in and take it. But do it quickly, the acid will dissolve the key in a matter of seconds. Make your choice.
Jigsaw: You will give everything to me. Every cell in your body. Is that understood?
Amanda: Yes.
Jigsaw: The marks on your arms, they're from another life. We'll leave that life behind. When you walk down that corridor there is no turning back. Do you understand that?
Amanda: [reluctantly] Yes.
Jigsaw: Then start with this.
[hands Amanda an envelope]
Dr. Lynn Denlon: What is it you want from me, Chris?
Chris: A divorce.
Jigsaw: Put his left leg in the shackle!
Jeff: He died in my arms! My 8 year old son died in my arms.
Dr. Lynn Denlon: [while Amanda is comforting John] He can't hear you. He doesn't even know you're there.
