Mrs. Patmore Frolics in Kate Middleton’s Coat:

Mrs. Patmore sneaks out (bless her heart) to help the former prostitute Ethel cook a lunch that doesn’t taste like crap. The coat she wore really looked familiar to us. Yes, it’s a more somber color than Kate’s, but Mrs. Patmore isn’t flashy.

Also funny–when Carson said, “If Mrs. Patmore wants to spend her time frolicking with prostitutes…”
Her response: “Do I look like a frolicker??”
