All they needed to do was transfer the TK power into someone who's already comatose and will be dead within the hour. Mrs. Silvercrest has been replaying the DVD sets so I've done a little catching up. The bronzing process involves cryogenically freezing someone, but they're somehow awake afterward??? And is why on Earth are the bronzer, and the bronzed people, kept in the Warehouse itself? The Warehouse organization should be storing them far, far, from anywhere. For the writers, keeping the bronzer in the Warehouse makes it easy to introduce peril. In-universe it makes no sense at all (for that exact reason).
