 CONT: The amount of donut on Glens plate while he and Maggie were  in the interrogation room keeps changing. After Glen eats the donuts  and finishes, only half of a donut remains. But when the FBI agents  walk in, it can clearly be seen that there is one and a half donuts  on the plate. And when the agent slides the plate to the center of  the table, there is only a half donut on the plate again.
