Shrek: [after an attempt to break Rumpel's curse doesn't work] I don't understand. This doesn't make any sense. True love's kiss was supposed to fix everything!
Princess Fiona: Yeah, you know what? That's what they told me, too. True love didn't get me out of that tower. I did. I saved myself. Don't you get it? It's all just a big fairy tale.
Shrek: Fiona, don't say that. It does exist!
Princess Fiona: And how would you know? Did you grow up locked away in a dragon's keep? Did you live all alone in a miserable tower? Did you cry yourself to sleep every night waiting for a true love that never came?
Shrek: But... but I'm your true love.
Princess Fiona: Then where were you when I needed you?
Donkey: [Fiona leaves] Maybe you kissed her wrong?
Shrek: No. The kiss didn't work... because Fiona doesn't love me.
