What news??? No one has said that she is returning.... Only that they are missing her, and she has been gone for far too long.
I have a creepy feeling that we have seen the last of Morag. I don't think the actress is interested in returning, and I think that the writers is not interested in having her back on the show either.
I will be very surprised if she ever comes back, especially if she is coming back for more than a wedding or a birthday.
With the clowns who are now running the show I wouldn't expect it either, all they can be relied on for is ****ty story lines, love triangles and continious bad boys coming into the bay.
