Rupert Graves and Jodhi May (minor spoilers)
Wow.
Just wow.
I know it's standard fare in these situations for the obnoxious upper class witch to go on her character's journey, then "see the light."
But that was really an amazing series of scenes. Tears flowing (c'est moi, not just the major's). Glad they hired two actors who could do justice to that one-off episode appearance/storyline.
Wow again.
