"Mad Men:" "Nothing happened here"

Apologies to AMC, who in fact did send out this week's "Mad Men" episode; it just arrived today (usually they're in my hands by Wednesday).

Last week's episode ended powerfully, with Betty (January Jones) receiving confirmation on something she's intuited for some time now: that Don (Jon Hamm) was cheating on her. This revelation gnaws at her as she's preparing a dinner party for Don and some colleagues. Eventually, and finally, she confronts Don; inevitably, he stonewalls.

"You think you know me - well, I know what kind of a man you are," she tells him, her sweet voice turned bitter and brittle.

Meanwhile, Father Gill (Colin Hanks) entreats Peggy (Elisabeth Moss) to work up a poster for a dance for young parishioners. Busybody biddies at the church find her work a touch on the risqué side and ask for changes, as if a chaste sales pitch will lure the kids in. "You asked me to do this based on my expertise," Peggy - who didn't think this act of charity would entail so many headaches - tells Father Gill, only slightly trying to hide her exasperation.

The episode sort of plays out in a prolonged hush. In one a disquieting sequence, characters sit alone, engulfed by the mistakes of their pasts. I know the feeling.

- "Mad Men:" 10 and 11 p.m. Sunday, AMC.
