"His old mother was the only person who never forgot".
This is a deeply sympathetic quote as it shows how much she loved him and how she would avenge him. In carrying out her plan, she showed no mercy. At the end of the story Widow Saverini feels relieved and very happy. She eventually sleeps for the first time since the death of her son.

This demonstrates that her grief stricken state was eased after her plan had worked.
There are many quotes that could show how innocent Antoine is.
"Antoine Saverini was treacherously knifed".
This quote shows that it was a vicious killing and that he was living in an environment full of danger and that he was an innocent man but knifed after a quarrel. Also it was a random violence and it could have happened to anyone on any other day.
We are made to dislike Nicolas Ravolati as he was the man who killed Antoine on purpose and without any reason. Also the fact that he ran away is another reason to dislike him.
"treacherously knifed by Nicolas Ravolati, who escaped to Sardinia the same night".
This is a quote of sympathy towards Widow Saverini and disgust and hate towards Nicolas Ravolati as he killed someone in such a bad way. The murder that Nicolas Ravolati committed could only be justified if one of Antoine's family had killed a member of Nicolas's family - and he was taking revenge - but we don't know that, and it could be only out of disgust and hatred which would not be justified as he would be breaking the law.

"And howled into space. Since her master's death, she often howled in this way, as if calling him. She would not be comforted, as if her animal soul also carried an indelible memory.
