Have you tried giving her TV shows to watch for homework, and then discussing them in class?
I do this with all sorts of shows (because I understand - after a year of 3 lessons a week, you've very often talked about everything that you could possibly think of). It doesn't matter which TV shows/films you choose. You just have to decide on one (which the student likes) and then both watch it for the lesson. I have a number of lessons already written here, and available for free (they cover IT Crowd/Sherlock/The Office/Jamie Oliver....I'm currently writing lessons for the old 'Game On' BBC comedy)
English Video Lessons - Skype Lessons
But its not actually necessary to use my lessons - they are just for additional vocab + grammar and to give the TV show course some structure. You could just find something else which she would like to watch, and then watch it yourself too. That will give you something to talk about. She retells the plot, and then you discuss any themes which come up in the show.
