The name on the painting could have something to do with the posession of Daud, as it seems to be a lot more complex than merely an image of the victim. Delilah made the brushes for Emily's painting from Emily's hair. The name of the posession target could be one of multiple layers of a painting.

Emily could have been what ended Delilah's friendship with Jessamine, which Delilah sees as her life being taken away. If this is true, then Delilah is also taking revenge on Emily by stealing her body.
