When Hank is badly beaten, he names a member of the Warren family as the prime suspect. Bridey receives the results of the paternity test she ran on Adam, and the answer is shocking and definitive. The pock-marked man begins to send post cards from around the country to Adam, giving Nina and Agent Clements a real shot at catching him. In the past, we see how John's grief led to his affair with Nina.
