Lucy is Dante’s right hand gal.  She keeps track of most of the goings-on in the drug den, now known as "the House of Cards". 

 

She comes from a heavily dysfunctional family and has been on the streets since a young age. During that time, Dante rescued an already tough and hardened Lucy, and brought her into his patchwork 'family'. She has become a mother figure to rest of his foster children and is usually somehow the most responsible of the group.
