[Peggy and Jarvis] have this very witty banter back and forth where she’s constantly having to go, “Look, dude, I don’t need your help! I am fine.” But it’s a lovely dynamic between them because they’re both British. They both have that wit and that satire. Their language is a game of chess back and forth. It’s a great game that they play and I think they get tremendous enjoyment out of it. And their relationship grows over the season. They become very close. They also provide the comic relief of the season. You see the serious aspects of what they have to do but then you have these great moments of comedy between them. He becomes like her comic sidekick.
