I missed this episode the first time around -- I came in about 1974 or so. It would have been neat if they could have written Young Hi into some sort of recurring role (in fact, when I looked this up on IMDb I was thinking she might be the local that runs the officers' mess) -- but at least we did see the actress again in two other roles.
Very complex question, as Hitchcoc points out; the fact that Hawkeye did what he did changed very little for Young Hi -- or did it?
