My Question for Q&A:
(I'm halfway through the episode, maybe someone asks this later)
I remember thinking it when I first saw the movie (I was 13 or 14 at the time):
So, they came up with the idea to swap their faces. They cut face from one and sew it on the other, along with hair and all, they fattened (or thinned down) them to look like one another, they installed the voice-changing microchip, and all of that was given to us in the sauce of a coocoo-crazy movie science.
If we go to this handwaved pseudo-science, WHY NOT JUST SURGICALLY REPLACE THEIR BRAINS? Not faces, voices and physicality, but just what's inside their heads?
What say you?
