September 1920. Edith is asked to write a regular newspaper column. She is excited about the opportunity, but most of the family is not supportive. Isobel helps Ethel by offering her a job as a servant; however, Mrs Bird refuses to work with Ethel and consequently leaves. The new maid Ivy draws Alfred's interest and receives Daisy's resentment. Matthew believes that Robert has been mismanaging the estate and finds an ally in George Murray, the family solicitor. Mary is angry when she discovers that Matthew has been discussing this without her father, Lord Grantham, present.
Sybil goes into labour and Lord Grantham hires a famous obstetrician, Sir Philip Tapsel, upsetting Dr Clarkson and Cora. The two doctors disagree over Sybil's care, Dr Clarkson insisting that Sybil is suffering from eclampsia and should be taken to hospital but Sir Philip arguing that Sybil is fit and healthy.
Despite the disagreement Sybil delivers a girl and all seems well, however during the night she becomes very ill and dies.
The next day Cora seems to blame her husband for the death, because of his refusal to accept Dr Clarkson's argument that Sybil was ill.
Poor Sybil and the Crawleys. :(
