Wow, Sanctuary did it again with another great episode. There's a lot going on with the search for the keystone as well as the main plot regarding various deaths around the country. "Vigilante" wraps up the episode earlier this season about the death of a priest who guided abnormals towards the Sanctuary. Christopher Heyerdahl plays double duty with both Bigfoot and John on screen a fair bit, and hits the right notes and Bigfoot catches the killer, a guy who's off his rocker and wants to rid the world of Abnormals.
Helen, suffering from the affects of radiation, travels with John to find the keystone, hitting a few dead ends before recovering the real ones. While the extent of plot development is only finding the keystone and getting the map in the end, there is a real intimacy between Helen and John, and we see how comfortable they are with each other when John doesn't have the entity.
The only mark on the episode is Will's FBI friend. Seriously, why was she in the episode? All she did was act cutesy-annoying and bother Will. Surely there could can be a better way to tie the deaths with the priest's death.
The midseason finale is next week, and the team will be heading to Hollow Earth. So excited!
Score: 8.9/10
