Inigo Montoya wanted revenge. He wanted to find the six-fingered man and avenge his murdered father. He told this to anyone he came across. But there was another reason he was after the man, that he told no one and never would.
He was recounting the tale of his father's murder to the man in black when he was overcome with memories.
He remembered that day like it was yesterday. It was implanted in his mind and would never leave. He told people of the sword his father had made for the six-fingered man. He told them of the man's cheapening the price and of how he then killed Domingo Montoya. After that he let people believe it had ended with the man scratching Inigo on both cheeks with his rapier.
But those scars were not from a rapier. He had received them from a dagger.
He still remembered launching himself at the man after witnessing his fathers death. He still remembered the brief struggle before the man pinned him to the ground. He remembered the straddled legs and his clothes being torn off.
He still did not know if it all was to make him feel weak, or if the man had been saying this was all he would ever be good for now that his father wasn't around to teach him the art of sword making. He remembered the pain most of all. The unbearable pain, coupled with the man slashing his face with the dagger.
The memories were always too much for him. He found himself falling. He had to sit down. He ended up sitting on the rock beside the man in black.
Shaking his head he continued on, telling him why he worked for Vizzini.
The masked man looked at him wonderingly. "You do not tell the whole story. I can tell."
"You are mistaken, my friend," Inigo says emotionlessly. "That is all there is to tell."
Inigo was now fallen against a wall, the same dagger that slashed his face, implanted in his stomach. Thrown at him by the same man who had violated him those 20 years ago.
He couldn't give up now. He had to avenge his father and himself. For all the years of mourning his father. All the years of pain that followed such a break of innocence.
He now also had wounds in his shoulder and arm. But he was going to fight the pain and defeat this Rugen. Fight the pain and fight the memories that bombarded his mind as he looked at the man who caused them.
He didn't remember the ensuing duel after that. He never remembered leaving his spot on the wall. It was a blank to him. The next thing he remembered was having Rugen at the point of his weapon, giving him the same slashes he now bore. Telling him to offer him money, power, gifts.
And then with a sick sense of glee, he plunged his rapier into the man's stomach.
"I want my father and my innocence back you son of a bitch!" he said coldly, loving the look of pain in Rugen's eyes as they crossed for a few seconds, then lost all life in them.
Removing his sword from the abdomen of the Count, he let him collapse onto the floor.
Many people think that after exacting your revenge on someone there's a moment of happiness and victory. No. That may come during the act but afterwards, Inigo didn't feel a thing.
He left the room to search for Westley, not glancing back once.
