Headcannon about Nolan Price:
Nolan is a wizard from ilvamorny(the American wizarding school) and he actually works for the American ministry of magic. He took the job as the ADA because the ministry wants him to keep an eye on the muggles as a sort of "we can't afford for the world to almost end again because of an evil wizard" precaution. The reason hes able to work so many cases? Minerva gave him the timeturner that Hermione was using in PoA, because she met him when he was still in school and decided that he was responsible enough. He uses it so that he can work many cases at once. Sam has a feeling that something is off with Nolan, Jack knew 100 percent, and Nick is just oblivious. Everytime something REALLY bad happens(like the subway shooting) he's always afraid that another Wizarding war is about to go down because he was so traumatized by the last one.
He mostly focused on charms in school and is skilled at spells that have to do with persuasion, but he doesn't use his magic much because he might get caught. He was really good at Quiditch, but he preferred spending time in the libraries. He definitely would have been either a ravenclaw or a hufflepuff(sorry I don't know the american houses).
He told Grace immediately when they started dating, and was surprised to find out that she's a wizard supporter, because she has magic in her family. But Nolan actually got in a lot of trouble for telling her.
His family was a well respected Wizarding family, and helped a lot of muggle-born wizards during the war in the HP series. His mother was a muggle and his father was wizard. Both his brothers are/were very strong with their magic, but Thomas and Christopher went to a different school.
I think its a cool idea, and what if all the ADA's were some sort of auror(auer? Aouror?? Wizard fbi) and they make sure that the muggles behave themselves. Thats awesome in my opinion. Feel free to make your own theories building on this one, id love to hear yall's opinions.
