Shrek: [figuring out how to break his contract with Rumpel] If Fiona and I share true love's kiss, I will get my life back!
Donkey: [jumping out of his arms] Okay! This isn't a petting zoo! So where is this Fiona?
Shrek: Well, that's just it, you see. I don't know.
Donkey: You know, when I lose something, I always try to retrace my steps. So, uh, where did you leave her last?
Shrek: The last time I saw her... I told her I wished I'd never rescued her.
[realizing where she is]
Shrek: Oh, no.
Donkey: [cut to them approaching the castle] Shrek? Shrek! Shrek, no, wait! Wait, Shrek! What, are you crazy? That's the Dragon's Keep! They keep dragons in there!
