a. In all this, he becomes involved in the life of a young woman, pregnant, whose husband, an environmental radical, wants an abortion.

Is (a) grammatical?
It is definitely understandable, but I don't like the way 'pregnant' is placed. I think it should be 'who is pregnant'.
If the 'a young woman' was the subject of the sentence that kind of thing would work, but in this case, it is not the subject of the sentence.
