Two new nurses arrive at the 4077th, one of whom is Hawkeye's ex-girlfriend Carlye Breslin, from when he did his surgical residency in Boston.
Attention all personnel! The following tropes are assigned to the 4077th:
- Absence Makes the Heart Go Yonder: Carlye was happily married until she arrived at the 4077th. By episode's end, she's had an affair with Hawkeye.
- Cerebus Retcon: This episode gives Hawkeye abandonment issues dating well before the series started, making Trapper's leaving with no note that much worse.
- Change the Uncomfortable Subject: When Hawkeye asks B.J. if he ever cheated on his wife, Peg, he tells Hawkeye, "Never." When Hawkeye then asks if B.J. had ever thought about being unfaithful, B.J. says, "That's a different subject." Hawkeye responds, "Aha! So you have thought about it!" Which prompts B.J. to respond, "No, but it is a different subject."
- Commitment Issues: Hawkeye literally proposes himself into a corner of Carlye's tent in a misguided attempt to get her to stay.
- Deadpan Snarker: Carlye's wit is pretty much on par with Hawkeye's, and clearly a strong source of attraction between the two.
- Everyone Has Standards: Hawkeye insists that Carlye say he broke up with her if anyone asks.
- Freudian Excuse: Subverted, Carlye leaving definitely didn't help, but Hawkeye was a mess with her and before her.
- Green-Eyed Monster: Hawkeye appears to verge on this during his first conversation with Carlye:Carlye: No, he'll go back to advertising.Hawkeye: Ah, advertising.Carlye: Ah, does that white smoke coming out of your ears mean you've just elected yourself pope?
- Happily Married: In comparison to Hawkeye/Carlye dramatically making grand statements about love meaning you're obsessed with each other, and B.J. setting the stage for his own marriage issues, Potter has a minor b-plot about actually having hobbies. He's still in love with Mildred, but he recreates as well.
- I Want My Beloved to Be Happy: As much as Carlye had wanted Hawkeye to be more committed to her in their previous relationship, she also didn't want to stifle his surgical gifts, which factored into their breakup.
- Malaproper: A shocked Hawkeye accidentally says "surgical residency" as "regical surg-" before correcting himself.
- Married to the Job: Discussed. Carlye claims that she ended it (both times) because Hawkeye couldn't commit to anything other than his work.
- My Nayme Is: For some reason, Carlye's name has an "e" at the end of it.
- New Old Flame: Nurse Carlye Walton for Hawkeye, who lived with her when he was doing his residency.
- The One That Got Away: Hawkeye insists there's been nobody since Carlye, "Pale replicas at best". At the episode's end, he explains that he's okay with her leaving, but "she never altogether leaves".
- O.O.C. Is Serious Business: B.J. is floored when Hawkeye sees Carlye climbing out of her Jeep...and hides.
- Shout-Out: To Casablanca:Hawkeye: There are five MASH units in Korea, three evac hospitals, I don't know how many aid stations, clearing stations, hospital ships, whatever... and she had to land here.
- Special Guest: Blythe Danner as Carlye Breslin.
- Titled After the Song: The episode is presumably named for the 1945 Harry Warren-Mack Gordon standard.
