If Hermione and Enjolras teamed up to try to get Eponine to listen and actually absorb (which she did), perhaps together they could actually get her to act on the advice they gave her, even if it was something along the lines of calling child services in order to help Azelma and Gavroche.

How badly did it backfire? Pretty badly. Okay, she got some coffee cake out of it, and half of a sandwich, but the food here was free anyway, so whatever.

Wordlessly, Eponine transfered her cigarette into her right hand, and held up her left hand, palm towards Hermione. On it was a careful line, the dark pink of freshly healed skin, spanning her palm. "I'd say pretty badly. But it could have been worse."
