Ooo yes, I like the Easter Egg theoty, but I think it is very likely that he likes those names a lot too.
But yes, easter eggs. I rememeber when I read Half Moon Investigations.... 4/5 years ago? Man thats a long time.. But anyways I remember squealing when I saw Art Fowler when reading it. It was a great time and just... So many crossover opportunities.
YES A SUPERNATURALIST SEQUEL WOULD BE SO AMAZING!!!!!
