Purgatory

I was intrigued by this story in Welsh Icons about the new series of Being Human:

     

There are a few changes afoot when viewers meet the friends at the beginning of the new series. Werewolf couple George (Russell Tovey) and Nina (Sinead Keenan) and reformed vampire Mitchell (Aidan Turner) have fled their beloved shared house in Bristol and are looking for a new house to rent in Barry, Wales. They are also without ghost Annie (Lenora Crichlow), who is stuck in purgatory and desperately trying to escape.

The subtlety of the plot is proving too much for me. Do they mean that Annie has been left behind in England?
