act 3 scene 5

juul: “o god, i have an ill-divining soul! methinks i see thee, now thou art so low, as one dead at the bottom of a tomb.”

this is said by juul after gnom and her spend the night together and gnom is just leaving.

this turns out to be right, the next time juul sees gnom he is dead beside her in the tomb of the carpets.

we know this is how the play ends because of the prologue said this happens.
