Amanda leaves the house and takes Kerry's van, since John is still in there. They drive back to the lair.
John: Good work Amanda. I am proud.
Amanda: Thank you John. Now, I have to tell you something.
John: What is that?
Amanda: You've been like a father and a mentor to me. And I thank you. But I think I'm ready to take your place.
John: Of course Amanda. You're definitely ready.
Amanda: I don't want you to be sad anymore. I'll make sure the world appreciates life like you do.
John: And you.
Amanda: Yes. But the only way you won't be in misery anymore, is if I give you the cure to cancer.
John: You mean, immortality?
Amanda: No. I mean the other cure to cancer...death. (pulls out the gun and aims it at him)
John: Amanda...put the gun down.
Amanda: Thank you for everyone. Hope life treats you well in heaven. Goodbye John.
She shoots the gun at his chest, knocking him down. He begins to bleed to death, but makes a grin, right before he dies. She begins to cry and decides to watch the monitors. Kerry is trying to find a way to get the key down the hole, Heather is crying, Alison is putting her hand on her hand, as if she has a headache, and Daniel is staring at the message in the bathtub.
Kerry: Damnit! I can't get it!
Alison: Leave it alone. It's hopeless.
Kerry: Don't say that.
Heather: But she's right! It is hopeless! Even Daniel's spooked! Daniel?
Daniel: Look closer Daniel. In your dad's heart.
Kerry: What's he saying?
Daniel:...I'm a goddamn fool!
Alison: Daniel?
Daniel: The message wasn't in my dad's heart! It was right over there! (Points to painted heart on the side of the toilet) The note by my dad's heart was a decoy!
Kerry: That's nice and all but the key is still in that hole!
Daniel: All right then. I'll just stick my hand in the toilet.
Heather: No! That's just plain wrong. Besides, you don't have to stick your hand in the toilet, just the top.
Daniel: Oh yeah. Duh!
Kerry: Kid, don't do it. It's just disgusting.
He opens the top and reaches in to find a black bag. It contains three things: a tape, a photo, and a key.
Heather: Give me the tape.
Alison: Give me the photo.
Kerry: And let me see the key.
He gives the items to them. Heather plays the tape.
Hello,
If you want to see Diana again, I'll give you a hint at where she's at. She's in a 'safe and secure place'. Hahahahaha. Maybe you should've stayed at the station, Officer Kerry, instead of beating me up for me to take you here, just like what Eric did. The timer in Jack's pocket signaled when the safe would open. Poor Diana, waking up here, wondering where she is and what's going on, just like before. I bid you all a found farewell.
Kerry: No fucking way!
Alison: Look at this.
Alison shows them the photo. It's the picture of Alison and Diana tied up, the same one Adam and Dr. Gordon found. Alison screams. Kerry calms her down and then tries out the key, surprisingly, it's the key that unlocks the chains.
Kerry: Holy shit! It works!
Alison: Thank you God!
Alison steps out of the chain, followed by Heather, and then Daniel. The four of them open the door.
Daniel: The moment of truth!
They open the door and Daniel dashes out.
Amanda: Nice try. (She has the gun aimed at his chest and shoots him. He falls over, Alison screams, and Kerry aims her gun at Amanda.) You didn't think it would be that easy, did you?
(Daniel is dying)
Daniel: Alison...Alison...
Alison: I'm here Daniel.
Daniel: I'm gonna get to be reunited with my father. (smiles)
Alison: May heaven be good for you.
Amanda: Ahhhh, isn't that sweet?
Kerry: It's you!
Amanda: You can't shoot me first.
Kerry: I can try bitch!
Alison, despite all the fear she's in, remembers the glass that Daniel used to stab Jack. Alison runs into the room.
Heather: Alison, what are you doing?
Alison: Hold on a minute!
Amanda: Apparently you want to die.
Kerry: Shut up bitch!
Alison walks out and fakes a seizure. Heather freaks out, thinking she's really dying. Kerry does too, but keeps the gun aiming at Amanda. Amanda reaches down with the other hand to grab her, just like she did with Laura. Alison the jumps up and stabs Amanda. She falls over. Amanda wakes up in the dark bathroom, chained to the pipe. She sees Alison at the door.
Alison: This is the end of you Jigsaw. I'm gonna get my daughter back, and sadly, you'll be chained to a pipe.
Amanda begins to laugh insanely.
Amanda: Good work. Hahahahahahaha.
Alison: I'll be the one with the last laugh this time bitch! Game over!
She closes the door on Amanda, who is still laughing insanely. Alison looks down at the dead Daniel, cries, and says her goodbye. She goes outside where Heather and Kerry are waiting in the van. They drive over to the police station where they find Diana on the ground with a gas mask on. They take it off of her.
Alison: Diana!
Diana: Mommy!
They give a huge warm hug, Diana cries with her mom and Heather and Kerry cries too.
Alison: I missed you baby.
Diana: I missed you too mommy.
Alison: I love you.
Diana: I love you too. Mommy?
Alison: Yes?
Diana: Where were you at this whole time?
Alison: Oh...I was helping out Officer Kerry.
Diana: I felt so alone.
Alison: I felt alone without you too.
They hug again. Kerry offers to give Heather, Alison, and Diana a ride home. They accept. Alison and Diana lives happily ever after. But Heather committed suicide a month later, 'to join her beloved Adam.' And although things went back to normal for Officer Kerry, she still remembers her cases with Jigsaw. Investigators found the house a week after the game Daniel, Alison, Jack, Heather, and Kerry played., along with the bodies of Addison, Jonas, Obi, Laura, Gus, Xavier, Jack, Daniel, Det. Matthews, Adam, Zep, the leg of Dr. Gordon, and the strange guy with the hooded robe and painted face in the room with the furnace. Investigators finally opened the bathroom door to find something strange. It wasn't the dead bodies in there, but the living one that shocked them. She was almost dead, and was lying on the ground, still chained to the pipe. She looked up at them and grinned.
Amanda: Investigators, I'm ready for my closeup now. Hahahahahaha.
Reporter 1: Who the hell is this?
Amanda: Game over. (grabs the hacksaw)
