About Nurse Beddoes[]
We only see Nurse Beddoes once. Hawkeye has passed his longjohns to Trapper who has lost it to Radar in a poker game. In the mess tent, Hawkeye meets Beddoes and asks her to sit with him to keep warm. Beddoes says she cannot as she has promised to sit with someone else. That someone else turns out to be Radar! Radar proceeds to show off, inviting her to feel the longjohns, much to Hawkeye's annoyance. Radar offers to get Beddoes some more pie. She accepts, saying, "I gotta keep my energy up for later." (They obviously have a date). But Radar then trades the longjohns for a whole leg of lamb offered by the cook, so he breaks the date with Beddoes.
Later, when Hawkeye needs to perform an emergency appendectomy on Henry, he asks Radar to get Nurse Beddoes to assist - she must have been the nurse on duty that night.
