About PVT Weston[]
When Klinger becomes mysteriously ill and delirious as the 4077th gets swamped with a horde of casualties, and one of those brought in is DOA - a young man named Weston. As Weston body is put off to the side, we see what can only be called Weston's ghost rise up from it. Klinger is somehow able to see Weston, and communicate with him, but of course no one else can. Is Weston even there, or is he a figment of Klinger's fevered imagination?
As Weston wanders about the camp, he watches people squabble over life's "petty" problems; the surgeons, Hawkeye and Charles argue over which nail each of them gets to hang their clothes on in the Scrub Room, B.J. and Margaret squabble over which fork B.J. likes to use in the Mess Tent, etc.
Weston can't quite accept he's dead, because he says he "doesn't feel dead." He gets upset when he sees his friend Hicks shed tears over his death, uncomfortable over Hick's glossing over all of his faults, just because he's dead. He watches B.J. and Father Mulcahy go through this personal effects, like his wallet, which he fondly recalls getting for the first time. While watching Hawkeye, B.J., and Winchester get drunk, Weston starts to feel different - he says that it starts to look like "everyone is made up of little dots."
Finally, Weston walks across the compound, and we hear random snippets of conversations taking place all over the 4077th - some of them serious, some of them silly.
On a road outside the camp, Weston is greeted by another soldier who is also dead. He points down the road, partially covered in fog, and they walk down it together, along with some other recently dead. They continue walking until they're out of sight.
