My little origins (V)

On the way back, Donkey discovers that Fiona is under a curse which causes her to turn into an ogre every night at sunset (and then turn back again the next morning). The only way to break the curse is to receive "true love's first kiss". While Fiona laments to Donkey that she is ugly, Shrek (who having finally made up his mind to propose is bringing flowers to her) overhears this part of the conversation and thinks that Fiona is calling him ugly.
