The actress is best known for her work with the Royal Shakespeare Company, most recently in productions of King John and Richard III. On British television, Dionisotti played recurring roles on Harbour Lights and Forever Green, and guest-starred on programs such as Doctors, Midsomer Murders, and Poirot.
Lady Waynwood (spelled Waywood on the CV, likely a mistake) is the head of her house, and sworn to House Arryn of the Vale, much like Bronze Yohn Royce whose casting was revealed last week. Similar to Royce, she was not present in A Storm of Swords, but it appears that the lords and ladies of the Vale are making their collective presence known early.
In other casting news, Gabrielle Dempsey will be playing the part of an Innkeeper’s Daughter in the first episode of season four, according to her CV. A 2010 graduate of the Central School of Speech and Drama, this will be Dempsey’s first television role.
There are a few inns in the book that forms the basis of season four, and so it’s not clear which innkeeper’s daughter Dempsey might be playing. The most notable inn is visited by Arya and the Hound but the first episode of the season seems far too early.
Ours is the Fury: I can think of a few reasons to introduce House Waynwood earlier along with Royce, so this is more good news. Dionisotti is a great actress, so I think she’ll be a wonderful Lady Waynwood.
