Just a small thing, but why wasn't Spratt informed ahead of time that the Dowager's luncheon with Lady Shackleton was set up to help Moseley shine? I thought that was very shallowly constructed. Would not the Dowager have known Spratt to be haughty and suspicious?
(A few of the 'situations' throughout Season 4's first episode were off character, too coincidental, etc. but this luncheon scene was almost silly. I still love this show incredibly, though!)
