I’ll be totally honest I started writing Walking the Blades pf Truth to rewrite Harry’s fifth yeat because I couldn’t stand the fact that Sirius died. I think that if Sirius had been able to do something besides stay in that awful place he would not have done half of the reckless things that led to his death. So what job that I give him? The Ministry of Magic still believed him a murderer so it obviously couldn’t be something walking around in human form. At first glance it couldn’t be anything that made use of Padfoot either because the Death Eaters were most likely aware of him. So I thought, and I thought some more. I was already toying with the idea of sending a Muggle born disabled child to Hogwarts and then it clicked. A collar could be enchanted to make Padfoot look like a golden retriever and he could be at school in the guise of a service dog.
This does not mean that Harry will not have to deal with Dolores Umbridge. As you might imagine she is going to be just as awful to Pheya as she is to Harry though for different reasons. If you read up to the current installment which is only chapter 2 you know Pheya makes a big deal about actually being special. Growing up disabled you hear that word so many times you get sick of it. I was in high school when the Harry Potter books started but I will tell you that I ate them up because there was a series of books that did not treat the disabled or chronically ill (Mad Eye Moody and Remus Lupin) as unmentionable or nonexistent, that in fact showed them as strong, capable even cool adults.Hephaeta is supposed to be a feminine form of the name Hephaestus Greek God of the forge who was also lame. Her dad would have named her that even if she had been able bodied but wondered many times when she was small if his choice of name doomed her to the fate of her disability. Totally irrational but guilt and grief often are. Pheya is not a transfer student she will start as a first-year and will not be in Gryffindor, meaning that Sirius’ interactions with Harry will be limited but at least he will be able to keep aneye on him.
