I wasn't expecting Dottie's homicidal fondness for Peggy, but Peggy's her equal in a way that most of the women Dottie interacts with are not.

And I really like the way Dottie and Peggy have respect for each other - a she's-capable-so-I-won't-underestimate-her sort of respect. It's always great to see female nemeses who don't descend into school-ground-type bitchiness.

Actually, Jarvis isn't the first butler whose age I've over-estimated, so that makes sense...
