China Beach

KC makes it clear to Colleen that the subject of the baby is not to be brought up again. This helps explain how Colleen would have known all along in previous seasons (episodes set after this one but produced before) that KC had a child but never discussed it.

The events in this episode with McMurphy arriving in Vietnam precede any other. If the series were shown in chronological (rather than production) order, this would be first.

This is the first ever episode in which the romance between Major Lila Garreau and Sgt. Pepper gets it's confirmation.

When Beckett is first speaking to Sgt. Morgan, Beckett calls himself by the rank of "Private", but is wearing the rank of "Specialist 5", a higher grade than Private.

When Sgt. Morgan is introducing himself to Beckett, he specifies his rank as "Staff Sergeant" but is wearing the rank of "Sergeant", which is a lower rank.

At the end of the episode Dr. Richard recites to McMurphy the famous Shakespeare's Saint Crispin's speech from Henry V given at the Battle of Agincourt: "We few, we happy few, we band of brothers; For he to-day that sheds his blood with me shall be my brother."

According to Boonie "Chao Ong" is a greeting that means hello and goodbye.

In the opening of the Hot Spell episode everyone at China Beach is trying to beat the heat. McMurphy steps over a fence and stands in a lawn sprinkler. It is very clear that she is wearing shorts and combat boots, yet as she bends to get closer to the water source she is clearly barefoot.

McMurphy now has three medals – one that was given to her by Dewey as he left the hospital to go home and the two that the VC Nurse (who had been awarded by mistake) left her as she was leaving-escaping the hospital.
