Graham asked Stuart Gibbs:

Mr Gibbs, I am a Spy School and Hamilton fan. However, in Hamilton I noticed that the character Hercules Mulligan spies for the American army. also, In spy school, the Hale family are all spies and are direct descendants of Nathan Hale, Another American spy. now that I have reread Spy School, I wonder why aren't there Mulligan descendants in Spy School and if they are going to be mulligan characters in later books?

Stuart Gibbs I only made hale descendants because I figured it was funny if there was one family of spy descendants, but the joke would get old if there were two families. So I probably won't have any Mulligans in the books. Although i reserve the right to change my mind about this.
