(Rick can't forgive that Ilsa's gone back on her word[1]. He refuses to lend a hand to Laszlo by not offering the exit visas, though Laszlo promises a extremely high price. Learning this, Ilsa determines to go alone to see Rick.)

Rick: How did you get in?
Ilsa: Stairs from the street.
Rick: I said this morning that you'd come around[2] but this is a little ahead of schedule. Well won't you sit down.
Ilsa: Richard I have to see you.
Rick: Oh, it's Richard again, we're back in Paris.
Ilsa: Please.
Rick: Your unexpected visit isn't connected by any chance with the letters of transit. I think as long as[3] I have those letters I'll never be lonely.
Ilsa: You can ask any price if you want but you must give me those letters.
Rick: I went all through that with your husband, it's no deal.
Ilsa: I know how you feel about me but I'm asking you to put your feelings aside for something more important.
Rick: Do I have to hear again what a great man your husband is, what an important cause he's fighting for?
Ilsa: It's your cause too. In your own way you were fighting for the same thing.
Rick: I'm not fighting for anything any more, except myself. I'm the only cause I'm interested in.
Ilsa: Richard. We loved each other once. If those days meant anything at all to you...
Rick: I wouldn't bring up Paris if I were you, it's poor salesmanship.
Ilsa: Please, listen to me. If you knew what really happened if you only[4] kenw the truth.
Rick: I wouldn't believe you no matter what you told me. You'd say anything now to get what you want.
Ilsa: You won't feel sorry for yourself, don't you? There's so much at stake and all you can think of is your own feelings, feelings. One woman has hurt you and you'll take your revenge on the resty of the world. You're a coward and weak. (Breaks) Richard, I'm sorry. I'm sorry but you are our last hope. If you don't help us Victor Laszlo will die in Casablanca.
Rick: What of it? I'm gonna die in Casablanca too. It's a good spot for it. Now if you'll...
(He is astonished at seeing that Ilsa's holding a small revoler in her hand, pointing at him.)
Ilsa: Alright, I've tried to reason with[5] you. I tried everything now I want those letters. Get them for me.
Rick: I don't have to. I've got'em right here.
Ilsa: Put them on the table.
Rick: No.
Ilsa: For the last time put them on the table.
Rick: If Laszlo and the cause mean so much to you, you won't stop at anything. Alright I'll make it easier for you. Go ahead[6] and shook. You'll be doing me a favor.
(Ilsa shivers. Then suddenly, she breaks down, covering her face with her hands. Rick walks to her. She flings herself into his arms.)
Ilsa: Richard, I tried to stay away. I thought I would never see you again. But you're to my life.
(Ilsa explains the whole matter to Rick. She marrired Laszlo young with a feeling of worship which she supposed was love. Months after Laszlo was apprehended by Gestapo and send to concentration camp, word came that Laszlo was shot to death when trying to escape. Then Ilsa met Rick, and found him the true love. When she were to leave Paris with Rick, a friend came to tell her that Victor was alive. He was very sick and needed her. She made no choice but left without saying goodbye. Rick forgives Ilsa, and for a more important cause, Rick deals with the enemy and helped the Laszlo get on the flight.)
