Dialogue/Incident in a story that propels the action, reveals an aspect of the character, or provokes a decision. The story is the Tell-Tale Heart by Edgar Allan Poe!!

I don’t understand the question but I’ll answer it as much as I know from the story.

The narrator wants to kill his old man because of his eye. He thinks his eye is a vulture and hates it. He try’s to convince the readers that he is not crazy and it perfectly sane. When he decides he wants to kill him because of it he goes into his room for 7 days a night and watches him sleep. He can’t kill him when the old man is asleep because his eyes will be closed. On the eighth night the old man hears something and him and the narrator stay still for an hour. The narrator knew that the old man was terrified and could feel it. The narrator then made his lantern a little crevice dim ray and saw the old man’s eye and then heard a heartbeat. He held the day upon the eye and then waited. After waiting he threw open the lantern and leaped into the room, dragged the old man on the floor and pulled his heavy bed over him(which basically means he killed him). The last thing he hears from the old man are the heartbeats. The narrator then dismembered his corpse(cut off head, arms, and legs) took 3 planks of wood flooring, and put his body under there. He put back the 3 planks of wood. As the bell sounded the hour, 3 police officers came to the narrator’s house. They got word from a neighbor who said they heard a shriek in the middle of the night. The narrator then lets them in, examines his house, and they also questions . The narrator said he was “absent in the country”. He thought to himself that his manner and how nicely he was satisfied the police and he was going to get away with murder. He then starts hearing a heartbeat. As it keeps going, it gets louder and louder. The narrator at a point couldn’t take it anymore then admitted his crime of killing his old man.

So technically we see that the narrator is well, crazy and mentally ill. He couldn’t take how loud the heartbeats were.
If i didn’t answer your question(bc i don’t really get what the question is asking) please let me know! Thank you!

Counterclaim text which gives it a defensive manner
