Eponine lives with Cosette in their house.
Eponine is named after Eponine Thenardier from the book Lés Misérables by Victor Hugo.
Eponine Pontmercy was born two minutes before her sister, Cosette to Marius and Fantine Pontmercy. Eponine was the rather more arty one, with Cosette being more braun. Eponine wore pink dresses while Cosette wore camo shirts. At age 16, Cosette and Eponine made a pact that if in 15 years the two of them hadn't been married, then they would join the army. At age 30, the two realised and remembered their pact, and moved to Riverview. Eponine and Cosette started training together.
