will be on Scifi channel
I have checked the Scifi website and this show will have episodes on starting Friday, October 13 @ 10 eastern or 9 pm central. They only have the episode listed upto "Progeny". I don't know if they're just airing all the episodes they aired or all the episodes that were ever made. If you know anything about that, please post something. I'm assuming it will be on every friday at that time but check your local TV schedule for local air times.
