It took several months, but even straitlaced, self-flagellating Prohibition agent Nelson Van Alden succumbed to Atlantic City's wanton pleasures like whiskey and loose women. But it only took one night in heaven with Nucky's castoff mistress, Lucy Danziger, to throw a huge curve onto his straight-and-narrow path. Nelson's indiscretion comes a couple of episodes after he heartlessly insists to his barren and miserable wife, Rose, that she not seek medical attention and instead trust in God to bring them a child. In Season Two, Rose, still infertile, learns of her husband's illicit affair and illegitimate daughter when she pays him an unexpected visit. Despite Van Alden's protestations that he planned to bring the baby, Abigail, home to Rose to raise as her own, she abruptly files for a divorce, no longer able to trust her secretive and philandering husband.
