Just a note, but in the article about Hicks and Newt and their potential futures, it should be observed that an early (and, presumably, completely different) draft of Joss Whedon's '
Alien Resurrection' script dealt with a cloned version of Newt. Don't know if she would have been a teenager or young adult, but considering the time at which it would have been written, may have served as a template for the superior - and emotionally believable - TV version of Buffy (who, ironically, also turned out to be a long-haired blonde).
The script's never made it to the public domain, but would be interesting to see if it contains any of Buffy's later more memorable/poignant lines.
Possibly not a conscious one, however. I recall that he mentioned being surprised when a fan pointed out to him the obvious similarities between the Betty crew and the one from his much later '
Firefly' TV series.
Also, do you know where to find a larger version of this image from your site? Been searching for ages!
