Jamie nodded, leaning down a bit on the ladder so as not to tower over the other man. "Human transfiguration, yes. From what I've read, it was said to force a person into the opposite gender...rather painfully. Not precisely what I need. But, I'm hoping that if I can study it for a bit, I can extrapolate what I do need from the basic theory."
The last thing he wanted was to give Scorpius something that would basically be like the gender equivalent of being a werewolf. Or something that would just push him from one gender to another. But, Jamie figured he had to start somewhere and gender transformations weren't something wizards generally practiced or wrote about with the rare exception of metamorphmagi. They were still working on full societal acceptance for homosexuality, after all. And Scorpius had already been pushing the boundaries of gender roles before this. So, Jamie needed to work with what he could find, which wasn't much.
"The books I had access to at home were the sort that would probably have reference to that spell. At least some of them. Dad inherited Sirius and Regulus' house when Sirius died," he explained. "So, I grew up there and the library was made up of the Black Family's books. I think Dad gave them back to Regulus and Sirius. So, I'll have to ask one of them for access now. But, I wanted to be sure of what Hogwarts might or might not have had, first." Thinking back on the professor's first question, he shook his head. "I didn't think of the journals. Did Hogwarts keep any? I did my studies, but I wasn't much of a researcher in school, not until I had to be for the job."
