Theory as to what became of Vanessa
By now if you're reading this thread you noticed that Vanessa from the first film was revealed to be a Fembot "all along". Basil also comments that he knew the whole time but I believe this was just a joke to speed the story along.
I believe somewhere during the infiltration of Virtucon Vanessa got replaced by a Fembot duplicate as kind of back up plan in the event Dr. Evil's main plan failed. So what happened to the real Vanessa???
1. She died in the explosion and her remains were never found.
2. Dr. Evil is holding her captive somewhere. Presumably in some remote location in Nevada.
3. Vanessa survived the explosion but is an amnesiac.
4. Vanessa survived the explosion but has been in an coma the whole time.
5. Vanessa survived but opted to keep her survival a secret and is doing black ops type work for the MI6 or retired from the Spy Life and is living under an assumed name in an undisclosed location.
If there's ever a chance to bring Liz Hurley Back for Part 4, it would be nice if they was to tie up that loose end but I highly doubt that they will since Austin Powers is played for laughs.
