Jon is His Mother

"Dad? What the hell is going on?" Jon asked. "Dad? Jane, do I look like your father to you?" Jon's father asked. Why did he call him Jane? That was his mother's name. Then realization came to him.

This *must* have had something to do with that vague wish he made the previous night. But if Jon was his mother, what happened to his mother? Was she Jon now?
