Hm. I just amused myself with the thought of how interesting it might have been if it turned out that future Admiral Janeway was in fact not a future Janeway at all.
There's plenty of that in Trek, didn't replacement doppelgangers turn out to be the Big Baddies in early DS9 realunch?
Oh and Kathryn J. would love to see the photo! That link leads me to a Twi'lek.
EDIT: clicked back and found the pic, thanks!
