It was the collapse of the market that finally did him?

Are those dot's supposed to be a space, like a fill in the blank? Im just going to interpret it that way.

"It was the collapse of the market that finally did destroy him"

dramatic irony occurs when the reader/audience knows more about a character's situation than the character does. the one main effect is that it gives the reader a sense of superiority, or detached superiority. the reader not only seemingly discovers what is revealed, but feels superior for doing so.

roses are red,

violets are black,

for what you said,

i hope you sit on a big fat tack.
