Smaller subplots first: Bobbi, for some reason, won't seem to go away, as she shows up to Don and tells him she's got an idea for a TV show starring Jimmy, and then apparently succeeds in getting in his pants again. Roger's daughter is engaged, and she defies her parents by insisting on not having a big splashy wedding. The nostalgia of his own wedding sends Roger into the arms of a hooker he once knew, as will happen. Peggy meets a young new priest at work, and he asks her for help with an upcoming sermon he has to give. Her assistance renders the speech a big hit, but this raises the long-simmering ire of her sister, who spills the beans about Peggy's pregnancy to the priest in confession. The priest, in turn, subtly lets on to Peggy that he knows, so we'll see where that goes.
Finally, Don and Betty are being amorous and romantic at the beginning of the episode, but things go south as Bobby keeps acting up. Don has to give him a talking-to, but it falls short of Betty's expectations, and things get more tense when a change in the American Airlines timetable not only forces Don to go in to work on Palm Sunday but to take Sally with him. We get to see everyone in their casual clothes, but Sally makes up for the comfortable atmosphere by talking about boobs with Joan and sex with Paul. On the day of the big pitch, all the players at SC wait anxiously in the conference room, only to find out from Duck that their big contact over at AA just got canned that morning. In the wake of this disaster, when Bobby acts up again at home, Don snaps and throws something, leading to a yelling and shoving match between Don and Betty, and some cracks in the Don Draper mask might be starting to show. I mean, we all figured Don's dad beat the crap out of him, but to hear him admit it to his son and wife is another story.
As a sermon can be heard in the background, we start on a close up of two gloved hands holding a booklet that holds "The Church of the Holy Innocents" Passion Sunday order of events (the date is April 8, 1962). We then see two boys who can only be Peggy's nephew and son, because next to them in a pew are Peggy, her sister Anita, and her mother. The sermon is of the fire-and-brimstone ilk that likely made Peggy stop going to church in the first place, and when the priest gets to the part about people living worthily and having their own crosses to bear, Peggy says she's not feeling well and walks out, much to her sister's annoyance, particularly since she needs Peggy's help with dinner. However, in the anteroom, Peggy runs into another priest, who... hey, it's Colin Hanks! I personally haven't seen him in anything since they killed him off on Roswell! Could it be that we were once so young? Well, he was, anyway. After finishing giving two apparently naughty boys a talking-to, Colin Hanks introduces himself as "Father Gill." He recognizes Peggy as "Katherine Olson's girl" (I seem to remember that this method of reference was common back then) and mentions that he's a visiting priest, and also, he's having dinner over at Anita's. This is enough for Peggy to change her tune and head back in. I don't think the sermoner would approve Peggy thinking the new priest is cute as an example of worthy living, but he'll at least be happy she's inside when the collection plate gets passed.
Cut to an overhead shot of Don and Betty having a morning lie-in. The phone rings, and Betty groggily answers and mumbles some things about a barbecue they're apparently supposed to attend, and Don's half on top of her practically before he's even opened his eyes. What's the story, morning glory? He breathes that Betty should cancel, and with a mischievous look, she does, telling "Caroline" that Don isn't feeling well. They reschedule, and when Betty hangs up, Don tells her he had an amazing dream. He doesn't mention if the dream was about her, but given the Valentine's Day droopiness, I suppose she's not in a position to split hairs. Their foreplay is interrupted, however, by the kids rushing in, and Don barks at them to get out. "We're... sleeping." Heh. I just hope the bed's strong enough to take it when you're "awake." Sally's got a great "I didn't just fall off the turnip truck" look on her face, but regardless, Don kicks her and her brother out and gets back to his, uh, nap.
