"Yeah, bottle," Eponine says, distractedly. "Please, I mean." She's not exactly used to good manners.

As soon as the bottle's on the bar, Eponine presses the top to her lips and begins to guzzle. She doesn't stop until the bottle is completely gone. Blood drips from her mouth and down over her chin. Just as quickly, she wipes the sticky blood from her face, and sucks on her fingers to make sure every bit of the blood is consumed.
Meal completely consumed, Eponine grins sheepishly at Nancy.

"That were a bit disgusting to watch, weren't it? Sorry. 'Parnasse says I eat like a pig, but I don't care. It fills the belly, doesn't it? I should rather a full belly than to eat proper and lose half my meal 'cos I am too slow."
