Pete spots Howard and Beth Dawes on his commuter train and she awkwardly blows him off. Later, he gets a call from Beth, telling him to meet her at the same hotel he wanted to meet her at a few episodes back.
"I'll be under the name Mrs. Campbell. This could be your last chance," she says cryptically.
Turns out that by "last chance," she means "last chance to have sex with me before I undergo shock therapy treatment (um, yeah, really random).
Turns out Beth is "blue." Pete pushes back the sympathy to have sex with sad Beth and then asks, "Don't tell me you're not happy now. Don't tell me you're not better."
As if sex with Pete Campbell is the cure to depression. Maybe it is. But I doubt it.
"I should go," Beth says.
"Why?" Pete responds.
"Because it works," Beth says.
Later, Beth undergoes the shock therapy treatment and Pete visits her the hospital, posing as her "brother." In what is definitely the saddest hospital visit ever, Beth doesn't recognize him as Pete relays how much in love with her he is and that it's the biggest issue in his life and how sad he is at home with his wife.
"He needed to feel that ... he knew something," Pete says, telling his story as if he's talking about someone else. "That all this aging was worth something."
Beth says that the hospital can help with that situation and that's that. Pete's out the door.
He goes home and Trudy shows him a mock-up of the pool that she wants to install.
"I don't know, Trudy. It's awfully permanent," Pete says, in what is perhaps the worst response to a wife wanting a pool.
Pete eventually confronts a drug Howard on the train about his treatment of Beth and they get into a brawl (Pete gets punched again!). Howard is dragged off the train, but after the guy taking tickets urges Pete to apologize, Pete refuses and he's punched (again!) by the train conducter.
When Trudy sees a battered and bruised husband come home, all she can say is that they're looking for a apartment for him in Manhattan "first thing in the morning." In what is perhaps the most clueless moment ever by wife on TV, she apparently buys his excuse that he "drove into a ditch."
Seriously, did you expect Pete and Trudy to last this long.
The final montage scene was epic. Not only did we see Peggy spotting two dogs mating, we see Roger Sterling's bare butt as he preens in front of the window.
Again, one of the final scenes of Season 5 is of Roger's bare butt. Should hold you over until next year, right?
