"Her romance with Tom will be one of the main storylines of the series. He will begin to develop feelings for her and they start a secret affair. Tom will have an even bigger role in the new series after becoming the estate manager of Downton. The writers know he is a very popular character and the viewers were gripped by Lady Sybil's traumatic death."
