During his life in District 10 he had worked on one of the beef ranches, maintaining the genetic diversity of the herd with the implantation of long-frozen cow embryos.
He suggests to Katniss that District 13 needs all the refugees they can get because, ever since a pox epidemic killed many of their own and left even more infertile, they have needed a new genetic gene pool to draw from in order to have children and make their population more sustainable.
Dalton was part of a small group of District 13 people who were invited to a meeting by Haymitch Abernathy to brainstorm ideas to help the propos for the rebellion. It was apparent Katniss could not act well and the idea was suggested that she go to District 8 to visit an area that was bombed and that the footage be used for a promo/message to President Snow. At this meeting Dalton suggests that they should "wash her face," and goes on to say, "She's still a girl and you make her look thirty-five. Feels wrong. Like something the Capitol would do." Katniss later mentions that she is glad she washed her face because people recognize her with her imperfections, not the makeup.
- He is the only named person to live in District 10.
