A flashback from the last movie plays,
as we see the aforementioned envelope was indeed placed into Gordon's
office. More flashbacks follow, showing Gordon becoming Jigsaw's
disciple after surviving his test just like Amanda did. This all
fits perfectly and fixes various plotholes such as “how the hell
could a civil engineer perform such advanced surgery?!” that has
been hovering around these movies since the second one.
What's REALLY fascinating about this
reveal has nothing to do with the movie whatsoever. January 18th,
2009 YouTube user Toberoon uploaded a video called “Dr. Gordon
is alive!” where he posited a theory that Gordon survived the
events of the first movie and became Jigsaw's apprentice. One of his
biggest pieces of evidence was the opening Billy tape from Saw II,
which showed a cloaked “Jigsaw” limping towards Michael's
unconscious body to implant a key in his eye. Remember in Saw II when I asked you to remember
that? This is why.
Toberoon turned out to be 100% correct, as the
movie even shows him doing the surgery on Michael. Keep in mind,
this was uploaded before even Saw VI came out with its
spoilery envelope scene, so this video is some kind of amazing. Many
people have speculated the producers of Saw viewed this video,
smacked themselves on the forehead, and changed their plans to copy
it because it makes so much damn sense. Now I doubt this, as the
limping man HAD to always have been intended to be Gordon but
still... it does make one wonder.
