and so far we haven't had any evidence that TV!Harry ever had
Yes, that! I was wondering about that. I'm really curious to see how many of Harry's family-friends show up on the show if (and when, knock on wood!) they get a second seasons. It made sense for plot development in the first season to have it be kind of Harry (and Bob!) against the world, and Murphy be the reflection of his struggles with the normal world.
But in a second season, it would make sense to bring in folks like Thomas and Michael and Elayne, or one or two of the secondary characters, to flesh out Harry and Harry's past. And Mister and Mouse! I would love to see Mister and Mouse.
As much as I like the show I hope they don't go much deeper into the mythology behind the magical world much more than they have. I love that mythology, but I don't think they format they're working in--scfi MOTW with added continuity--really lends itself to the grand political details Butcher describes so well in his book.
And gosh I really love Blackthorne. So much!
SPN: The supernatural newsletter, much like its other fandom counterparts, is a mighty and awesome resource. I'd read it if I wasn't skirting fandom at the moment. I already got spoiled for the Bones finale from a damnable flickr set, and I have no intention of being spoiled for Supernatural.
