With Shink acting as our secret informant, the Death Council never expected that the contact that they had worked with so many times had suddenly become their mortal enemy. Since the Death Council wasn't on guard against Shink at all, capturing the Death Council members went incredibly easily.
Although it was still the "same Shink" waiting for them at their typical meeting location, Shink was now loyal to a different party. It took only a single moment for the dark ranger to capture all of them.
