Lord Darnley to Mary in Playing with Fire

Lord Darnley is one of the main characters and main antagonist in the final season. A nobleman with a blood-claim to the English throne, he became Mary's second husband, a union which could take down Elizabeth, giving the couple not just one nation, but two. He is also the ex-lover of Lady Keira and the father of Mary's child.

Early Life

His father was originally Scottish but later betrayed the Scottish for the English. He has a blood claim to the English throne.

Throughout the Series

Season Four

Lord Darnley makes his first appearance in With Friends Like These.


Darnley is kind, charming, and breezily confident. However, his strengths are overshadowed by his blinding ambition and focus on self-preserverance, which he reinforces throughout the series. And although he appears to be confident, he is shown to be very insecure, particularly in his lack of real power. Since he is the King Consort, he feels as though he is not Mary's equal but her underdog, which bothers him and he resorts to expedient ways of gaining power, to the point where he actively works against Mary and her people.

In Coup de Grace, Mary described Darnley as "not a complex man". She said that all Darnley ever needed and wanted was to be loved and respected. Darnley confirms Mary's belief by repeating it throughout the series.
