Makes sense to me.  They could at least bond on the level where Davis is clearly passionate about the music, and her songs.  But he wouldn't think twice about changing them up in the middle of a show, and clearly isn't professional.  Davis would ply all his charms on her when he could, though he wouldn't be pushy if she clearly wanted nothing to do with him.  He'd try to at least get her to party, get wasted, have an orgy, and bond with Davis that way.  He's probably more entertaining to her when his antics are at a party rather than a show.
