(Unkind) Spiteful Madame Thénardier

Lore
Surrounded in the deep red roses, Madame Thénardier smiles with contentment. here she can be free of any concern of her husband's metamorphosis or the arrangement of her daughter's undesired marriage. As she caresses the rose blossoms, a thorn catches her hand, and a red drop forms on her skin. though it seems like a bad omen, a twisted grin passes over her face as she licks up the cimson liquid.
