Thank you very much for reading and caring enough to comment. I appreciate it. No, Jack's gender wasn't switched, he's still a man. I don't know if he's supposed to have a vagina and womb canonically, or even where they would fit if he's just a giant head in a jar? It's very mysterious. But for the purposes of this fic, I decided that he has a female reproductive system always, and not just once in a while when he feels like it.
