The unnamed Vietnamese woman was the lover of Eddie Blake, aka the Comedian, while he served in the Vietnam War. She was present in Saigon in March 1971 when Jon Osterman (Dr. Manhattan) arrived in Vietnam and was reintroduced to Blake. On V.V.N. Night, in June of the same year, the then-pregnant Vietnamese woman accosted Blake in the US Embassy's Saigon Officers Club, slashing him across the face with a broken bottle when he refused to accept her unborn child as his own or offer his support. Blake was permanently scarred. In revenge, Blake shot her dead, along with the unborn child.
Although Osterman witnessed the confrontation, he chose not to intervene, which Blake called him on after Osterman asked him if killing the woman was really necessary. Blake pointed out that Osterman could have stopped the killing and that Osterman was "falling out of touch" with reality.
