Sam: I’ve got a bad feeling about this.
Cherlyn: After 28 years of marriage, I know every feeling you got!
Sam: I’m your husband.
Cherlyn: Well, of course you’re my husband. Unless you want to be that evil black beard again.
Sam: Why am I here?
Cherlyn: Oh no you don’t! Don’t you start that!
Sam: Start what?
Cherlyn: That…that craziness about hearing voices. Not another word.
Sam: I heard voices?
Cherlyn: I said not another word.
Sam: But what do you mean?
Cherlyn: That is it! That is it. You have gone and done it. You have ruined everything. I am no longer in the mood so you can hang up your holsters until next Saturday night...Aren’t you gonna stop me?
Sam: Stop you?
Cherlyn: I’m gonna call my mother!
(She leaves the room)
Sam: Oh boy!
Al: You’re not going to believe this yo-yo in the Waiting Room.
Sam: Larry Stanton?
Al: Lawrence Stanton III, actually. You’ve a lucrative law practice in Baton Rouge, Louisiana and your counterpart in the Waiting Room thinks he’s dead.
Al: He thinks that I’m St. Peter and that I’m going to send him to hell for over-charging his hours. Reminds me of my last two divorce lawyers.
Sam: Do you remember Larry Stanton? I remember…uh…there was a hanging and a lot of people and he was hurt, I think he tried to save her.
Sam: No, no, no. Not her. That’s Mrs. Larry Stanton – she wants to melt me down!
Sam: Are they going to be all right, Al?
Al: Yeah. Ziggy says that since Sammy Jo is carrying your genes and now that you’ve cleared Abigail, the curse is broken. Abigail gets married in two years to a wonderful guy and they move to Chicago and she’s happy, Sam. She’s really happy.
Sam: How do you know all this?
Al: Sammie Jo told me.
Sam: Sammie Jo?
Al: Sammie Jo is working with us on Project Quantum Leap, Sam.
Al: Yes, and a matter of fact she has a theory on how to bring you back home.
Al: Ziggy hasn’t the slightest idea why you’re here. I suggest you open the door and see what drifts in.
Al: Don’t look at me, I don’t make up these assignments!
Sam: I have a daughter, Al!
Sam: Does she know that I’m her father?
Al: No. And Ziggy says after this leap you won’t know either.
Sam: I’ll know, Al. I’ll always know.
Sammie Jo: (to Sam) I’ll never forget you!
