"What's happening that's made you so upset" (line 274)?
"My lord, I can't say I've come out of breath... / Many times I stopped to think things over--- / and then I'd turn around, retrace my steps" (line 256).
"What man would dare this" (line 286)?
"Someone as buried it and disappeared, / after spreading thirsty dust onto the flesh" (lines 282-284).
"...could this act not be something from the gods" (line 323)?
"No one can tolerate what you've just said, / when you claim gods might care about this corpse" (lines 327-328).

The messenger was the unlucky man that was chosen by luck of the draw to go to King Creon and deliver the bad news of Polyneices' body mysteriously buried. At the beginning of their conversation, the messenger begins by saying that he was very hesitant to relay the information because of how he knew Creon would react. This is very important because it shows that Creon is known to be strict in enforcing his rules and can become very harsh if someone disobeys them.
After the messenger comes to the conclusion and makes up his mind that he is expected and counted on to inform Creon of the news, he begins explaining how the body was discovered. Creon does not receive this information calmly, and instead begins questioning and threatening the lives of the guards who found him and those involved in the illegal burial of Polyneices.
As the messenger continues explaining the details of the despised burial to Creon who is growing more and more furious, the Chorus Leader inserts a comment that strikes Creon the wrong way. Creon snaps back responding with intense questions as to why someone could be foolish enough to believe that the gods would ever care about a body that killed a king. This single quote is a vital part of the plot because it plainly states that Creon believes that his own laws are higher than divine laws.
