Who is Valjean? Who is Cossitte? What is the relastion of Valjean and Cossitte? What charactiristics does Valjean have? this is my project.......
A discussion of who each of these characters can be found in the Character Analysis section of the enotes study guide. (Click on "Character Analysis," and then start with Valjean. Then read the discussion of the other characters. Those sections will sum up the characters and the relationship between the two that concern you most.
As for the forgiveness, I think you're talking about the Bishop's choice to give Jean Valjean a second chance. That's discussed in Themes section of the enotes study guide.
Jean Valjean is an ex-convict who spent 19 years in the galleys. He's inexpressively generous and kind and he has a true Christian heart. When Fantine died, he undertook the job as a 'father' for Cosette, the daughter of Fantine. Having never experienced love or care, his love for Cosette as a 'father' bloomed through the years.
Valjean is an ex-convict. Cosette is the daughter of Fantine. Is taken care of by the Thenardiers, but is used as their personal "slave". Valjean takes care of cosette and Valjeans characteristics are helping the poor, redeeming himself etc. Its in the enotes study guide.
