Season three of "Downton Abbey" ended with the death of Matthew. Mary had just given birth to their son. The trailer of season four - which is here - shows a Mary who is suffering to the point of despair. Granny tells her she must choose life or death.
Since Matthew's death some of us viewers have been wondering how this loss will affect Mary. Until now, as the oldest child she seemed cold, judgmental, and bossy. Now we find out that she really did at least have deep feelings for her husband. Will this dramatic shift in her circumstances soften her? Will she feel more compassionate of what others are going through? For example, will she understand why spinster sister Edith could take up with a married man?
Or will Mary harden into a bitter woman who has the responsibility of rearing a child? If she withdraws into a shell that will be a burden to the family as it tries to catch up with modern times. Mary, it's possible, could become the wrench in the smooth operation of a family just getting its bearing after losing daughter Sybil.
