This was a great treading-water episode. We've reached a particularly pleasing point in the storyline, and it makes sense to stop and have a picnic and enjoy the view.
I liked Roger's arrival home. The suitcase seemed not to be empty, which isn't always the case when characters are carrying suitcases around. And the way Roger looked around the foyer was very nicely done, as well as the whole set-to with Vicky, Carolyn, and Joe. But I agree with EmeraldRose that 6:30 in the morning is strange time for him to be getting home. Oh, well, maybe Liz didn't want him to leave Boston last night.
I've never liked either Carolyn or Vicky much, but I liked the scene with them in the drawing room, after Roger and Joe left. That's a very nice friendship.
The caretaker, in his Peter Pan collar, is one of my favorite minor characters. He and Roger really ought to be bosom buddies. Imagine them, two totally clueless guys discussing the state of the world over a glass of sherry - but I suppose every clueless person is clueless in his own way, so Roger's and the caretaker's minds will never meet.
