"Briggs: [to his team, speaking about Ethan] Listen up. An American operative with a grievance against his country is missing and has malfunctioned. His agenda represents a threat to our national interests, and he must be neutralized at all cost. Anything in this man's possession is of vital importance and must be captured intact. The man himself is expendable. He is not to be underestimated. A master of infiltration, deception, sabotage, and psych warfare. For all intents and purposes, ladies and gentlemen... a mind-reading, shapeshifting incarnation of chaos. So, for your safety and the safety of those around him, do not consider him secure unless you have driven a wooden stake through his open heart. This is not a drill."
