Vengeance

SPOILERS for S4, E3! Vera was still at Downton. Not physically, no one ever saw her. But spiritually, yes, she was very much there. After she took her own life, she thought John would finally get what he deserved. But no, that little Anna of his had to get in the way. Now John was out of prison, and Vera was not happy. Vera sees the house party as a chance to strike back.
