If you fear for your life and know for a fact that an assassin is planning to kill you, because they believe in false accusations made by others. Fake your death by suicide until the ambulance picking you up is at the hospital. Do this so the lone ambulance attendant who makes the ride to the ER doesn’t murder you.
Hope the killer gets conned by a member of We “R” US, a doctor on board a Boeing supersonic about to be airborne, convincing the assassin to leave the plane’s makeshift ER. Then the doctor can takeover and save your life.
Ultimately, the secret agent should be reassigned to South America for failing to make the hit. Only then will you understand what blank stares are about.
