Below is a sneak-peek clip of the mid-season finale of Sanctuary on Syfy! The series has enjoyed another successful start to its third season and will be finishing with a treacherous mission to the hidden city. Adam and Dr. Magnus exchange some potent words and fits of arrogance and fear are tossed around when the language brings family into play. Magnus knows she must lead her team to the city, but both Tesla and Druitt want to join the excursion. Dr. Magnus confirms that it would be too risky for them to come, and only creates more of a liability. Watch the clip and tune in to see if their voyage is successful and if the team can work together to make it in to the hidden city on the mid-season finale this Friday, December 17th at 10/9c on Syfy.
