Eponine

Destitute street wench, desperate lover, professional piner-from-afar, lacker of several marbles, wannabe romantic heroine, unwilling criminal, unlikely savior, and all-around very strange young lady, Eponine Thenardier is one of the protagonists of Les Misérables. According to Agent Maria Falcone's CAD, her species is "French." Make of that what you will.

Thanks to a mix-up by the Floating Hyacinth, she is apparently now an intern at the PPC.

Character History
Often depicted wearing a trademark big floppy hat, Eponine is a street girl who lives in the apartment next door to Marius with her family of criminals, whom she often serves as a lookout for. She's head over heels in love with Marius, but he's in love with Cosette, so she helps him out in any way she can in her own little stalkerish way. She creeps him out, but she's one of the closest things to a friend he has. After he decides to join the ABC to commit suicide by cop, she decides to do so as well, believing they will die romantically together. She can't go through with it, though.

She's the same in the musical, though we do get a bit more of her side of the story, which has inspired a lot of badfic.

In Badfic
She's beating off possession Sues with a stick. Alternately, she's a heinous bitch who does everything in her power to break Marius and Cosette up. The latter type often crops up to spite or parody the former, and really just serves to prove that Eponine is simply too complex a character for Suethors to grasp.

PPC
Ep is considered a rather high-risk character by the PPC due to the aforementioned possession Sues. One particularly atrocious fic featuring her being tortured and molested was slain by Agents Chliever and Winston, and she herself was portalled to Medical, from which she escaped. She currently resides in RC 77, very much intrigued by Chliever and Winston's washing machine. A series of small but annoying coincidences conspired to make her stay in the RC much longer than necessary, culminating in the Floating Hyacinth mistaking her for an intern, causing something of a Catch-22: the Agents can't send her home without being chewed out by the Marquis for getting rid of an intern, but if they reveal that she's not an intern, they'll get chewed out by the Hyacinth for hiding a canon.
