Nathan Horton is Melissa Jennings son. He came to Salem to intern at Salem University. He resides with Maggie and Mickey Horton, along with Mia and Melanie. He's a decent guy, caring and is getting friendly with Melanie and Stephanie. He fell in love with Melanie, but she married Philip Kiriakis, so Nathan tried moving on with Stephanie. They moved in together, got engaged, but when Nathan learned that Stephanie lied about Parker (Jonas) Kiriakis' paternity, he left her. He also admitted to himself he never stopped loving Melanie. Nathan felt there was nothing left for him in Salem when Melanie rejected him, so he moved to Baltimore, for an internship with John's Hopkins. He will return to Salem shortly.
