Medical question (huge spoiler, if you didn't see it RUN YOU FOOL!!)
Ok so Robert was a great... plastic surgeon? molecular biologist? whatever. Let's say he had the skill and technical prowess to do the sex change (kind of simple nowadays) and even the seemingly perfect face transplant (orders of magnitude more difficult in this day an age. Though now I think about, it could have been not a face transplant but plain old plastic surgery, but I digress), but were the physionomic changes addressed at all by the plot?
I grant that Vicente was short and kind of "delicate" but there is still a MALE SKELETON there beneath that skin... you know, wide shoulders, thin hips, marked eyebrow arcs, etc. Is there any possible explanation for Vera to have such a gorgeous feminine body, or is it just artistic license?
