Questions about The Diplomat (no spoilers for season 2)

[CitrusPocket]

I’m only on the first episode of S2. Who is Margaret Roylan again?

arch conservative mentor and advisor to the prime minister

Thanks and why is she missing?
I should have put all my questions in the OP! 😳

And why is Kate's phone call to her so important? How is that linked to the car bomb?

If you knew the answer, then it would be a spoiler!

Forget the main storyline, their marriage is WEIRD!!!!

My husband is hot as well but also can't stop meddling in my career. WIBU to LTB?
