Orphans getting injured in minefields while searching for scrap to sell and a young pregnant woman being shot, risking the lives of both her and her baby.
Being a father himself, Colonel Potter is naturally alarmed by the news of the orphanage being shelled, showing vivid concern for the children.
Androcles' Lion: B.J. tells the original story to the orphans bunking in the swamp. They fall asleep before he can finish but Hawkeye wants to hear the rest.
Ascended Extra: Nurse Kellye is the nurse that assists B.J. and Margaret in Sung Lee's Caesarean.
Beware the Nice Ones: An unrepentant Frank, on the lookout for a kid he assumes to be a thief, comes into the OR during his search and demands help from Colonel Potter, ignoring the wounded that have been brought in. After he ignores the colonel's order to get to work, Potter enlists Father Mulcahy to force him to scrub. The father responds without hesitation, dragging Burns into the scrubroom.
Big "SHUT UP!": Frank complains about having to take the orphans in again on account that they steal. Potter's response:
Colonel Potter: Burns, shut your face.
Bloodier and Gorier: More of the former when wounded are brought to the hospital. Lampshaded by Colonel Potter.
Colonel Potter: Let's get some of this blood off the floor.
Cerebus Syndrome: The episode starts off fairly lighthearted as the 4077 provides shelter for the orphans and spends time with them, then Sung Lee, whom Meg had been worried about, stumbles into camp after having been shot.
Companion Cube: One of the orphans steals Radar's teddy bear to sleep with. Radar gets it back at the end but also gives the kid a doll in return.
Continuity Nod: Colonel Potter asks Hawkeye medical advice in the OR, reminding the audience Hawkeye's chief surgeon.
Deadpan Snarker: Hawkeye noting the condition one of his patients is in during surgery.
Hawkeye: Send his X-rays to his draft board in case they like horror pictures.
Foreshadowing: Nurse Cratty comes into the Swamp, asking for a drink from the still, and expresses worry about Sung Lee who should have been at the 4077 already but is not.
Fridge Horror: In-Universe, Radar realizes he's singing a lullaby about her parents still loving her though her daddy's gone to war to a war orphan.
From a Certain Point of View: Frank received his Purple Heart for sustaining a wound described as "Shell fragment in the eye." Hawkeye, who treated that wound, immediately points out that said shell was an eggshell that got caught in Frank's eye when he panicked and broke the egg.
From Bad to Worse: Incoming wounded arrive just as B.J. and Meg begin to operate on Sung Lee.
PA Announcer: Attention, all surgical staff. Heavy night patrol action. Stand by for incoming wounded.
Hawkeye: Wounded. 4:30 am.
Hawkeye: You can set your watch by this war.
Getting Crap Past the Radar: Margaret, accompanying Frank looking for the Korean boy at the Swamp, looks down a picture scope belonging to either Hawkeye or B.J. and screams in horror.
Hawkeye: Once there was an army doctor. A bad, bad Major. And what did he do? He pretended he deserved something that only certain soldiers can have. He accepted a medal he wasn't entitled to.
Frank: If you think I don't know who you're talking about, you're a dumb Dora.
Loophole Abuse: The shell fragment Frank was apparently wounded from was a shell all right. An eggshell.
Frank: Nevertheless, it was the result of combat and it's on my service record as shell fragment.
B.J.: You were breaking open a boiled egg and got nervous.
The Main Characters Do Everything: When the doctors and nurses unanimously decide that a Caesarean is necessary to save both Sung Lee and her baby, Potter asks everyone if they have any experience in the procedure. Meg can't because of her arthritis and neither can Hawkeye as it's been some time for him. The task eventually falls to B.J. solely because he's fresh out of residency. It's all justified though as there is no time to call in an expert.
Mundane Made Awesome: Col. Potter's dramatic reading of a rifle maintenance manual and making it sound like an adventure story for the kids sharing his tent.
