Why is it ironic that blackie spoils the Shy Man’s plan to rob the house?

i believe the answer is inference

in my opinion i think it was not excessive at all. the maids turned against the queen in his absence, how could he ever trust them again? if he let them go they would surely spread the news of the suitor's deaths, which is much too risky. as for the suitors, they were selfish, rude, and greedy. the god's had apparently marked them for death, meaning odysseus made their death come faster.

i think your answers would be c and d☺
