Shell isnt 2 obvious at all, considering Debra Stephenson is with Corrie, and come out of Bad Girls 2 years ago. She got shipped off 2 the funny farm, which would give no reason at all for her return. Debra has hinted she could return as kno-one knows whats coming. It would be a great cliffhanger if Debs did come back for one ep.
I could hardly see it being Bodybag, but hey who knows. I cant see it being anyone from this series or the last to do it either. A longer running cast member would have a lot of reasons to do it
