The mum found her real mum, and discovered she had been in prison for the neglect and death of her other dd.
She then realises she has treated her own dd badley and rings her only to discover she is in hospital having the baby. She gets there just in time and the daughter has a baby boy. The nan goes to visit them in hospital and has a stroke.
Eventually they all go home again and live happily ever after.
I thought it was a bit dull and boring and predictable.
