So far this season Sanctuary is running a touch over 1.3 million when you factor out Chimera - which you have to do because their split showing leaves one unable to accurately know how many viewers it actually had. Last season the move to Tuesdays with no advance announcement hurt them and they pulled a 1.15. So they are up somewhere between 150,000 to 200,000 over last season. That is good.
