Consider me thoroughly impressed. Sanctuary continues to push the boundaries, this time fully exposing the dark origins of the Five and the Sanctuary network. As we dig deeper into the show, the entire foundation of the show, and of which the title is based from, is shown to be mired in dirtiness.
The Five, with their enhanced powers, were employed by the British government to track down and take down Adam. Their reward was the funding they needed to continue to Sanctuary network, and we can assume that's where Magnus's great wealth comes from. It makes you wonder if they did anything else for hire, thinking it would also benefit the public.
We also learn how Adam is still alive. After falling off the cliff into a river, John found him, but let him go. From there, his body floated into Hollow Earth where he was revived. I can't say I'm too surprised, but he's the direct link to Hollow Earth.
In the meantime, traveling through space is extremely dangerous and has begun killing Magnus and Adam, inextricably tying their fates together. Magnus also retrieves John, who's hiding out in Cambodia, and she displays more badassery.
The biggest challenge for the writers is to keep the momentum going. So many times in the past, with the Cabal and its various schemes, the world seemed to be on the brink and the Cabal was poised to do something incredible. And then the situation dissipates and the Cabal is gone. Hopefully, the writers don't do that with Hollow Earth.
Score: 9.3/10
