Margaret phones Elizabeth asking her and Phillip for dinner with Peter.
Yeah, that lasted for about a minute before the slideshow got a whole lot more promiscuous.
Elizabeth plays dumb when Phillip starts wondering what this formal dinner could possibly be about.

Margaret is 23 and therefore cannot marry without royal permission until 25, which soon becomes important.
Hey, let bygones be bygones.
“Mummy, this is a surprise.”
“Why would you dangle Scotland under my nose?”
Peter and Margaret meet up away from prying eyes in a gorgeously shot scene.
(Where can I get Margaret’s riding outfit?)
They kiss one more time, and it’s all rather tragically romantic.
The press pays little attention to the Queen and keeps commenting on Peter’s position as “staff.”
Elizabeth gives Tommy the okay to do whatever he sees fit with Peter.
We’re treated to the sequence from the top of the episode as operators track down the Queen.
She’s finally found at Sandringham House and Margaret lets Elizabeth have it.
“You fail to protect me.
I will fail to protect you in return.
You reap what you sow, sister.”
A line has definitely been drawn.
I’ll be curious to see how Margaret’s lack of support affects their private and public relationship.
I would not go so far as to say enemies, but let’s go with not-fans.
Wallis Simpson and the former king are loving the turn of events.
The episode wraps with the nearly nonexistent Phillip taking off to a “perfectly innocent” house party.
Doubtful, very doubtful.
Storm clouds are brewing on the marriage front.
