I don't know. That was pretty deconstructionist of them. If there is a 4th season, they would have to do some serious rebuilding. I read that the Lois character was originally written to be Martha Jones (from Doctor Who) but she was busy doing Law & Order: UK so Lois was created. Also, Mickey Smith (also from DW) was to have most of Reese's lines, but Noel Clarke's off doing a film. I think it worked better not having two recognizable characters like that, though. However, if they do another season, I'd watch it if they get Mickey Smith back...
