Was Seth turning into a female fly?
At one point we can briefly see Seth’s penis in a jar, alongside other jarred extremities that have fallen off during the gruelling transformation. As nasty and depressing as this is, it doesn’t make much sense because the male
fly does in fact have a penis. Like many animals, their penis is internal and only comes outside the body during sex. So did he just grow a second internal penis? Or is he actually changing gender? Because he would have no reason to lose his penis if he were staying male.
This brings up a new question. If he got stuck in the pod with a female fly, would he actually change gender? Or maybe he would meet the gender halfway and carry characteristics of both sexes, much like he carries characteristsics of both species.
