Kathryn Prescott is set to reign on Reign Season 1.
But only for a day.
In casting news broken by TV Line, the actress (Skins) has landed the role of Penelope. The character is merely a kitchen servant... who finds a bean in her slice of cake and becomes temporarily queen, per castle tradition.
Described as shy, yet manipulative, Penelope will stick around for multiple weeks.
The series itself just returned from a long winter hiatus.
Watch Reign online right here and now if you need to catch up.
