We found the oldest post-seine fic, dated between 1875 and 1898 (there are two versions so far) this Spanish theatre adaptation of les mis is a wild ride
Below, I translate the scene in which Javert tells the truth about Valjuan (Valjean) to Marius, after arresting Thenardier
Javert: take him away! Monsieur baron, excuse my impertinence and permit me say a few words
Marius: speak, Monsieur inspector
Javert: I know what this scoundrel has come here to do. And my conscience dictates I make some clarifications
Javert: There's in your family a man with a extremely mysterious side. Nevertheless his mystery doesn't hide a reality of infamy and crime, but in expiation, redemption and honor
Marius: and in what are you based to say it, Monsieur inspector?
Javert: In what! I'm going to tell you. I met that man in a nefarious age for him, when he was judged and convicted for the first time. I met him again twenty years later, when I was inspector in pontardier and him Monsieur le maire. I did my duty and had him convicted again as parole breaker and thief. But with everything, he went to the court to denounced himself! He was then convicted in toulon,from where he escaped once more as you know how. At last , Monsieur, the day you saw him at the barricades, I was due to die and he saved my life. He saved you through the sewers, exposing himself to dying or being rearrested! I apprehend him then....but I don't know why....for the first time I felt that inside my chest mercy weighted more than justice. So not only I allowed him to escape, but now I chase ruthlessly an idea: to save him! Because it is true that Valjean is an exconvict, but I, who has been following his life step by step, I can assure you that his touch doesn't stain, doesn't demean. On the contrary, it honors, Monsieur baron, it honors and elevates!
It is also extremely funny how they do the pardon thing too
Marius: You are right! But, who will erase the stigma from him? Who will rehabilitate him?
Marius: And how to acquire it?
Javert: Me, rightious inspector Javert. Me, who I have sacrificed my whole existence guarding the State, I have asked as my only reward Valjean’s pardon. And I’m awaiting to be given it any moment now
Marius: What are you saying? Is that possible?
Javert: Yes… But I warn you that I doubt that it arrives on time, Valjean is dying
Marius: What?! Grandfather! Cosette! Go, my good friend, hurry your attempt!
Javert: See you soon, monsieur baron. God wishes I could pay Valjean what I owe him. He gave me life, now I will save his honor!
