An entertaining season premiere. I was surprised with how much they put out there. The Cabal is going on the offense to take down the Sanctuary and to build up their own army of abnormals.
The episode picks up where last season left. Ashley has been modified as a test subject for the Cabal to create their own abnormals. Ashley tries to fight back , but the scientists control her.
Ashley has several powers which makes her dangerous plus she has the source blood in her. Dr. Magnus and Will eventually find out what's happening due to their persistence of capturing a rogue Cabal informant, Kate Freelander (is that her real name).
In short, the episode introduced a story arc that seems to be the basis for season.
