The same question every week, just in a different way.

What if, after weeks of Benji not giving away anything at all about Ethan during the polygraph sessions at the beginning of Rogue Nation, the CIA decides to try a more persuasive measure by using an upgraded lie detector on him, which gives him small electroshocks every time he is caught lying? And as they are suspecting that Benji has so far outwitted their detector, being an agent who has had training in how to do that, Hunley tries to subdue him by yet another measure?
And how will Brandt and Ethan react later, when they find out?
