I expect they had a number of ideas for season 2, but I can't imagine they would write full scripts until a new season had been greenlit.
Many shows have a bible, a book of facts about the characters and or places that aren't actually revealed right away on the show but are the basis for certain plot lines or character behaviours. And this bible is consulted when writing episodes. A show's bible will reveal hidden back stories and random facts. I would love to have seen this show's bible, if it had one. And or the content of what Lisa Ryder would have read at her reading for Winifred.
I miss this show. Doctor Who just ended in the UK (in about three weeks in the USA) and Scifi finished it's run of Sarah Jane adventures. So we have more filler Stargate and Ghosthunter reruns to look forward to for months and months and months...
The Scifi channel lost it's fantasy aspect and is now losing Scifi itself. It's becoming some mockery of an unreality Reailty TV channel. Especially with the return of Scare Tactics.
God, I miss The Dresden files...
