Background:
[JVJ died jumping off a boat, and Javert adopted Cosette instead.
Javert thinks Cos Jav-raised would end up something like Mademoiselle Gillenormand. Except pretty.
Javert says, "If she rebelled as a teenager, her 'Papa' would beat her thouroughly."
You say, "Only once he caught her. If you were an informer's 'daughter', you'd get pretty good at being secretive."
You say, "Do you want to try that, then?"
You say, "It might be interesting."]
Javert takes Cossie from the Ts.
Then...
Javert takes Cosette home and raises her to be France's first female Inspector of Police?
Javert moves out of the attic of the police post and moves into an apartment with enough room so Cosette can have her privacy when she needs it. To do... um... girl stuff or whatever.
Javert laughs, pictures Cosette running into Jav's room in the middle of the night saying, "Um, Papa? I'm bleeding." And he of course rushes her to the hospital. All the nurses snicker at him.

Story:
Cossie walks the streets of Paris without fear, a gangly ugly young teenager taking notes on everything she sees. If it was a sketchbook under her arm, she would be a great artist, but instead, it is a book about the people of Paris, their habits and oddities.
Cosette observes very carefully.
Javert walks alongside Cosette, almost looking pleased at this girl who he's grown used to over the years, she perhaps can see this, even if the rest of Paris can't. He looks over her shoulder to her notebook and nods, appreciating her skill of noting everything around her.
Cosette says, "I think there's going to be trouble soon, Papa."
Cosette says, "Some of the students are really getting unruly."
Javert says, "Wise of you to note, Cosette, very wise. Yes, since the illness of Lamarque was announced, they will not hvae themselves silenced. But fear not, they will be silenced in short order when they try something."
Cosette nods. "I'm sure you're keeping a close eye on everything, Papa, and that Monsieur Gisquet is well prepared. He always is."
Cosette says, "I have faith in you, and in him, of course." She speaks M. Gisquet's name with as much reverence as Javert does, having only his example to follow. "I only hope my notes can be of some help to you."
Javert nods, "There will be trouble soon, and then it will be over." For any other lady her age, he would of course suggest she stay home until the storm is passed, but he knows her, he knows she can care for herself.
Javert smiles to her, and to her alone, "You are right to, we will care for you and the rest of honest Paris."
Cosette gives Javert a peck on the cheek.
Javert returns the gesture with a fatherly kiss on the forehead, "All right, I'll be home once I leave my post." and he goes off to where he will keep an eye out for wrongdoers for today, sure she will be fine without him.
Cosette walks down the street, saying, "Goodbye, Papa. Take care of Paris."
Cosette pauses to note down the passerby.
Javert smiles back to her, then turns his face to its chilling cold stare and walks away.
Cosette writes in her journal, 'Three bourgeosie, discussing Lamarque. They look nervous.'
Marius bites his lower lip as he watches the father and daughter part, for once, and he straightens as much as he can before walking in her direction.
Cosette continues writing, 'One student. Definitely nervous, and very scruffy. Perhaps on his way to a meeting of insurgents, as there is a nest nearby.'
Marius passes very close to her, only daring to glance at her and hope that she'll acknoledge his existance.
Cosette merely continues writing, not glancing at the boy whom she has already recorded.
Marius passes by her. He frowns, ignored. He turns around and begins to walk by her again.
Cosette looks up. "Are you lost, Monsieur?" she asks politely.
Cosette writes, 'Student seems confused.'
Marius drops his mouth open as if to speak, but is silent. She speaks! To him! >>> poetry, Marius, poetry! <<< he orders himself, "I-I" he stutters, "I am lost in the depths of your beautiful eyes, Mademoiselle." he manages.
Cosette blinks. 'I believe you have mistaken me for someone else,' she says primly.
Cosette looks back at her notebook, then realizes that the last three 'disheveled student' entries have been this boy.
Cosette says, "Or perhaps not. In any case, I think you should go now."
Marius takes a bashful half-step toward her, "I have never seen another as radiant as you."
Marius says, "I never want to look at another girl again, if she's not you."
Cosette closes her notebook with a bang. "Then you shall be sadly disappointed. I have a job to do here, Monsieur, and you impede me. Leave me alone, or I shall walk away from you."
Tears come to Marius' eyes. "Do not walk away, I beg you. I shall die if you do." Wiping his eyes with his jacket sleeve, "I will leave you. But I will always adore you." and he turns away to do as she has asked.
Cosette is completely unmoved. "If you do not want me to have my father escort you to the madhouse, you would be wise to leave me alone in the future."
Cosette says, "What is your name?"
Cosette opens her notebook again.
An audible sob, and he speaks, not daring to look back at her, "Marius." as he walks away.
Cosette makes a note of that in every place in the last several days where she's seen him. Then, she looks back at all the notes that were, she now sees, this Marius boy, and shakes her head. "I shall have to tell Papa," she says to herself, "and he will be upset that I didn't realize I was being watched sooner than this."
Cosette looks up as Javert comes home from his day at the post. "Papa, something very odd happened today. A boy, a student, came up to me and told me..." she consults her notebook. "'I am lost in the depths of your beautiful eyes, Mademoiselle.' I got him to leave me alone, but he said, 'I will leave you. But I will always adore you.' I think he is mad, and I don't know what to do.
Javert raises an eyebrow, "This was the first time you've met him?"
Cosette says, "Apparently not. I looked through my notebook. He's been following me off and on since some time in May."
Cosette looks at the floor. "And I didn't realize it. I am sorry."
Javert sits down across the room from Cosette. "Since last month?" he thinks. "You should have noticed, Cosette." he frowns, "You're usually so good at observing your surroundings." A pause. "Is he republican, do you believe?" Noting she said he was a student.
Cosette nods and points to several notes in the journal, turning it so Javert can read from it, too. "I saw him with the students who go to the Cafe Musain. He's usually with them, even in the times I've seen him recently, so I just counted him as one of the group. I didn't realize he was looking at me like that." She shudders. "He must be insane."
Javert stands up and steps closer to look at the contents of the book, reaching for it gently, "May I?"
Cosette says, "Of course, Papa."
Cosette gives Javert the book.
Cosette says, "You can see that I just recorded him as a student in shabby clothes until today, when he approached me. I never saw him looking at me with more than a glance."
Javert lifts the book and begins tooking through the pages at all the entries which he can tell have recently been added upon with the word, "Marius". "Marius?" he asks, just to make sure, as he reads.
Cosette says, "Yes. I was hoping he would give me his last name, but he did not."
Javert comments almost to the book as he reads, "I believe I have heard of him by way of my informants in the area. Seems like he's always daydreaming, they say." Daydreaming about his little girl? He shudders internally at the thought.
Cosette nods. "Either that or he's listening to those other students."
Javert nods and shuts the book, now addressing Cosette sternly but kindly, "While it is a great help to take notes on your environment, it helps even more to go back and read over them once in a while, looking for connections you may have missed previously." From his manner, he does not seem to be about to get angry at her, especially as no harm has come from the lapse.
Cosette says, "He frightened me, Papa. That he could have been thinking like that about me since I first noted him down, and I didn't even know. Why would he think like that about me?"
Cosette says, "Yes, Papa."
Javert says, voice gaining an edge of anger, "Because there are people, especially those sort of people, who do not care to behave toward young ladies like they ought to." and his voice softens a bit, "And, whether you see it or not, you are turning into a young lady. And a..." he thinks, not unsed to noting it about women, of course, "very pretty one at that."
Cosette blushes. "Oh, Papa." She thinks for a few minutes. "I think I scared him off, for now at least, and if he's with those students he won't live very long, anyway."
Javert nods, "True." he says shortly, and he gives her a supportive pat on the shoulder, "I'm sorry if you were frightened."
Cosette smiles. "I'm not, really, now that you're here. I just was for a few minutes, then, when that stupid boy wouldn't leave me alone."
Javert thinks, "Cosette?" he questions softly.
Cosette says, "Yes, Papa?"
Javert says, "Would you feel safer in situations such as that if I allowed you to carry a pistol?"
Cosette says, "He didn't want to hurt me. He was just a little intense."
Javert says, "Still. Paris, despite all my efforts, is not a safe place. And with all the tension right now, I think you ought to be armed. But I will not force you to carry a weapon against your will. What do you think?"
Cosette says, "If you'll teach me how to use it safely, then it would be good, I suppose."
Javert nods, "Very well. Tomorrow I will take you over to the station and teach you."
Cosette smiles. "Thank you. I don't think I would ever want to shoot someone, but to have the capability, well, that's something else."

Javert steps in the front door, looking generally calm but with a hurried aura about him. "Cosette?" he calls.
Cosette comes to the door after a moment. "Yes, Papa?"
Javert looks to her calmly. "It's started. I'm sorry, but I'm going to have to postpone our appointment for shooting lessons."
Cosette says, "Oh, dear. Do you have urgent orders?"
Javert nods, briefly saying, "Mm-hmm," as he steps across the room with a brief hug for his daughter then goes into his room and closes the door, "I'm going to go and see what's happening with a small group of students." comes his voice through the wall.
Cosette says, "Where will you be if I need you?"
A few moments of silence. Javert exits in plain civilian garb, frowning slightly at her, "Don't come find me. It'll not be safe for you. If you have a problem, go see M. Delphax at the post."
Cosette frowns. "If I promise not to come, will you tell me where you are?"
Javert looks to her, taking her at her word, "I'll be in the south Rue de la Chanvrerie." He leans down to kiss her a farewell on the forehead.
Cosette says, "Be careful, Papa."
Javert nods, "I'll be back soon." he silently adds, "I hope." as he steps away through the door.
Cosette waits at home for hours. As it grows later and later, she makes her decision.
Cosette changes into the boy's clothes she bought for just such an occasion.
Cosette gets the pistol she was to learn how to use, and sticks it through her belt. She also brings along a sharp knife.
Cosette smudges charcoal on her face to obscure her features.
Cosette heads for the Rue de la Chanvrerie.
A student standing near the edge of the barricade spots her as she approaches, "Who are you, boy?" he calls out.
Cosette says, "Theodule Thenardier. Vive le republique!"
Cosette nearly chokes on the words, but sometimes, it doesn't matter.
The student looks at the slight form, "How old are you?" They've already tried to get rid of Gavroche to little success, the last thing they need is more kids running about.
Cosette says, "Old enough to die for my country."
He pauses. "Fine, then, come over to the back alley, the barricade's smaller there, and you've got a better chance of getting over without being shot."
Cosette takes the advice and goes around.
Cosette climbs into the barricade and looks around, trying to conceal her disgust.
Marius sits, staring into space, on the inner edge of the barricade, nearby where Cosette enters.
Cosette notices that horrid student who approached her the other day.
Marius notices her as she notices him, and his eyes grow wide as he stares into those gorgeous eyes of hers.
Cosette bites her lip, thinking about how to deal with this boy. "Marius," she says softly. "Come with me."
Marius rises to his feet, not taking his eyes off of her, and he steps to her, saying quietly, "You don't despise me any more?"
Cosette smiles as sweetly as she can. "Come and see." She beckons him back into the Rue de Mondetour.
Marius smiles boradly and follows her, walking in a dream he's had, many, many times.
Cosette takes out a little knife while she is facing away from him and holds it in her palm, then turns to face him in the street outside the barricade. "Oh, Marius."
Cosette reaches out with her knifeless hand to gather him close.
Gavroche * No, that hand is down at her side. the other is reaching out to embrace him.
Marius mumbles, "Mademoiselle..." and reaches out reverently, almost afraid to touch the beautiful being.
Cosette pulls him close, whispering, "Marius," and kissing him. At the same time, she uses her other hand to slide the knife into his breast, and holds him to her to stop him from crying out.
Marius' face contorts into one of agony, and he tries to yell, but it is muffled in her shoulder.
Cosette holds Marius to her as he dies, then checks his pulse. Nothing. She retrieves her knife, wipes it on his vest, and sheathes it again. "Oh, Papa. Where are you?" she asks the air, then climbs quietly back into the barricade.
Cosette wanders through the barricade, observing.
Cosette looks at all the stupid students, and tries to stop herself from telling them that they will all die, no matter what happens.
A small group of students are standing about the entrance to the wine shop, the central organizational point of the barricade.
Gavroche says, "By the way, you'll give me his musket? I leave you the musician, but I want the clarinet."
Javert scowls slightly after the gamin as he leaves to do some errand or other for the rebels.
The crowd of rebels begins to disperse, now that the excitement is over.
Cosette catches a glimpse of Javert and begins to make her way toward him.
Javert looks to the door as another figure stands there now. His eyes widen slightly at the familiar face and form, then narrow. "You promised." he hisses at her.
Cosette bites her lip. "But you're tied to a post."
Javert glares, "I noticed. You still should not have disobeyed me. You are in danger, now."
Cosette draws her knife, still warm from the blood of Marius, and prepares to cut the bonds. "So are you. At least I am not a captive. And I didn't lie. I said 'if I promise,' not 'I promise.'
Javert frowns as there's nothing he can say about that, it being true. He looks down at the knife. "You've been busy?" he asks, noting the blood.
Cosette slices one of the cords, and unwraps the rest. "Yes. That boy I told you about."
Javert nods, "So he was here." He stands still, for now, next to the post, so that any rebels casually glancing in the door as they pass will not notice anything is wrong.
Cosette takes both of Javert's wrists and wraps the rope loosely around them so that it resembles another bond.
Javert * Dam. Hm. Didn't they store their meager surplus of guns and ammo in here?
Gavroche * For the purposes of our story, yes.
Cosette picks up all the ammunition she can find and gives it to Javert so he can hide it inside his coat.
Cosette lets the rope go so he can move for a few moments.
Javert pockets the ammunition. "Thinking to fight out?"
Cosette says, "No, just disarm them."
Javert looks to the door, the rebels running about now, frantically trying to get ready for the battle. "When the fighing starts, we'll try and leave, before they need to come abck and reload. A short window of time, but if we get it, we can get out."
Cosette nods. "Yes, Papa. Are you still upset with me, then?"
Javert looks to Cosette. "You're a very bright and promising girl. I don't know that I can stay angry at you for long. And for now, let's just try and get out. We'll worry about the rest at home." He looks up and out the door, waiting for the first sound of gunfire, the signal to move, and move quickly.
Cosette waits silently, reassured that, for now, she has a reprieve.

Bang.
A gun fires from the barricade. Javert springs away from the post, hopefully followed by Cosette, and reaches the door of the cafe as all the rebels are busy shooting.
Cosette follows quickly, a gun in her delicate hands.
Javert looks both ways then ducks along the side of the building, reassured that Cosette is with him, he pauses as the corner he turns provides temporary shelter.
Cosette says, "They are all going to die."
Javert nods, "Yes. Then order will be restored." and he herds Cosette in front of him this time, going towards the alley.
Cosette goes as quickly as she dares.
Cosette climbs over the short barricade, looking back for Javert instead of at the corpse of Marius.
Javert goes along behind Cosette, and they safely reach the alley, where they are free to hurry up slowly.
Cosette says, "Where shall we go for help?"
The sound of gunfire fades slightly as they walk away. "For help?" asks Javert.
Cosette says, "To end this silly riot."
Cosette says, "The National Guard cannot see that there's a back way into this barricade, but we know. I don't want you going back alone, Papa."
Javert looks to her. "First thing coming first: You are going home. Then I will return to the post to inform M. Gisquet of the back entrance, and the National Guard will be employed accordingly."
Cosette sighs. "But didn't I help you, Papa? And I wasn't hurt. If the whole National Guard suddenly stops shooting at the front and comes round to the back, they'll realize their mistake and shift the barricade. It has to be more subtle."
Javert blinks to her, "You've been reading up, haven't you? In any case, the Guard know what they are doing, and they will know what to do with the information I give them."
Cosette shakes her head. "They couldn't have saved you, even if they'd known you were there, and cared. I saved you. Me. Your little daughter. Please, trust me."
Javert says, "What do you contrive, child?"
Cosette says, "We would need five other men, all disguised, all young so that in the thick of things, they would not stand out from the other students. They could infiltrate the barricade as I did, just by walking in, and the leader is easy to spot in his popinjay vest. Once he is gone, the insurgents will lose momentum. A few more of the key players gone, and they will surrender. They are only brave because their leaders are brave."
Javert says, "Surrender? Only to be taken into custody and executed."
Cosette says, "But that is easier than battering the guards to death against the strongest part of the barricade."
Cosette says, "If you want to do this, now is the only time."
Javert looks at her, "All right, then. Let's go talk to the Prefect about it."
Cosette smiles radiantly. "Thank you, Papa!" She nearly runs off through the streets.
