Nelson Duvall is a minor character on How to Get Away with Murder. He is the eldest son of Edith Duvall. He and his siblings were all accused of poisoning their mother, however, it was later revealed that none of the siblings were accountable; it was his mother, Edith who poisoned herself.
After Nelson, Karen and Jared are accused by their mother of poisoning her with antifreeze, the two seek council with Annalise Keating and her teaching clinic. The students interview the three siblings. Nelson reveals to Michaela and Asher that his mother called her "Half Nelson" because he has a below than average IQ. Asher finds a possible suspect for the case due to a compromising email mentioning antifreeze. When questioned about it, Karen tells them that she was involved with the email, making them unusable. During Jared's deposition, the ADA asks Jared about his love life and Edith jokes about Jared's non-existing love life. This causes Jared to lash out at his mother and tells her that he wishes she was dead. At Edith's deposition, Laurel and Annalise question her. When Annalise and Laurel managed to get to the bottom of her lies, the ADA advises Edith to get her lawyer before answering any more of their questions. She insists that they should continue and she eventually cracks and admits that she poisoned herself as her children take her for granted and wanted to show them that they shouldn't. The prosecution drops the charges against the siblings. ("Call It Mother's Intuition")
