Jack patiently heard the female agent speaking, but could not listen to what was happening to Allen. Instead he focused on the agent's words about them, which were the thoughts he had on their way to the government facility they were. He decided to not say a word and instead started tapping his index on the floor. At first it seemed like incoprehensible sound, but one of the agents could understand that he was using Morse code. He learned that when he needed to co-operate with a partner in a card game. The message was saying: "I understand your concerns...please let me speak to the one in charge privately."
