Tristan: I live in torture, thinking of these moments. With every look he gives you, I get sicker and sicker. There is a burning in me I feel on fire, and there's guilt I can't get rid of either. Does it make you happy to know that?

Tristan: What's your name?
Isolde: Oh, I think it's better if we don't bother with names.
Tristan: How can I thank you if I don't have your name?
Isolde: You just did. If you insist, my name is Bragnae. I'm a lady in waiting at the court. My parents are dead. My mother is the source of the kindness you find so puzzling. My father would've left you where you fell.
Tristan: Tristan of Aragon.
Isolde: Well Tristan of Aragon, I'd guess about you too, but I think I've already seen everything.

Isolde: Tristan, if we do this...
Tristan: For all time they will say it was our love, brought down a kingdom. Remember us. *pushes the boat away*

Tristan: Come with me. Come with me!
Isolde: I can't!
Tristan: Why not? Please!
Isolde: Tristan, we both know this can't be, we've known it from the start. That doesn't mean it isn't true, it is, it just cannot be. I want to know that you're alive somewhere thinking of me from time to time. I want to know that there's more to this life and I can't know that if they kill you. Please! Go.

Isolde: If things were different, if we lived in a place without duty, would you be with me?
Tristan: That place does not exist.
Isolde: I'll pretend it's you.

Tristan: Your marriage will end a hundred years of bloodshed.
Isolde: *crying* My marriage to another man!

Lord Marke: Did I love him like a son? Or did I misuse him for my own purposes?

Tristan: You're promised?
Isolde: Yes.
Tristan: What's he like?
Isolde: Dark. Tall. Nearly twice your size. An absolute gentleman.

Tristan: You were right. Life is greater than death, and love is greater than both.

Tristan: I am delivered.
