Reminder, #Sanctuary fans, this week's new episode airs Tuesday at 10 as well as Friday at 10. You've got TWO chances to see it! Enjoy!
@scifistorm It's primarily to keep it paired with it's normal lead-in, which has a special Tues showing.
I've uploaded the Sneak Peek and Trailer for the episode to the Chimera page for your enjoyment!
