What was the deal with the elderly woman at the beginning?
And those children. At the beginning, the children are exciting about getting out of school but the KGB armed agents are outside. The children all stopped talking as they saw the armed agents. What, were children not allowed to express joys of leaving school and going home? Why would armed agents be outside a school anyway?
Also, when the agents broke into the apartment to find the agent who double crossed them, what was the deal with the woman. Did she not know they were police officers or were police offiers in Soviet Russia notorious for breaking into houses at the spur of the moment and attacking people. She was expecting to be raped so it seems.
