Once again, no one can live happily ever after 
Ronnie's baby James, dies and she puts his body in Kat and Alfies son's crib, and steals their baby boy, Tommy.
Why oh why oh why do scriptwriters insist on portraying bereaved parents - mothers especially - as mad and deranged??? Maybe it's because they can't begin to imagine how awful the death of a child is, but really, whilst we are mad with grief, it is our own child that we want back, not someone else's stolen child. When are scriptwriters ever going to understand that?
Still, it'll be a riveting watch, no doubt.
