About Aggie and B.J.[]
When a bus full of wounded arrive, they are escorted by a surprising guest - journalist Aggie O'Shea, who was following a few soldiers as they make their way through their tour in Korea, and then reporting on what she experiences. She meets with the doctors and Margaret afterward, and Hawkeye doggedly attempts to romance her. But Aggie seems only interested in...B.J.
While in Post Op together, Aggie becomes quite flirty with B.J., continually rebuffing Hawkeye's advances. Her interest in B.J. is so apparent that everyone in camp notices, even the wounded.
That night, the two share a drink in the O Club, and Aggie lays it right on the line, letting B.J. know she's "very interested" in him, leaving B.J. flush and stunned into silence.
The next morning, everyone in camp is talking about B.J. and Aggie. After a rough night's sleep, he has a talk with Aggie in the x-ray room where he goes so far as to ask Aggie how long she can stay in Seoul. Her answer is, "As long as you want." B.J. confesses that while he has feelings for Aggie, he can't give up his one life line - the one he has to his family. Aggie confesses that she loves B.J., and they embrace in saying goodbye.
Weeks later, a care package from Aggie arrives, with presents for everyone. Potter's gift is an original drawing by Aggie, one of B.J, with a life preserver around him, emblazoned with the words "San Francisco." When Potter asks what that means, B.J. answers, "Beats me."
