Homes was described as an "older guy" who never says much but can "shoot the dust off your boots at fifty yards". During their mission in the Capitol after Boggs transfers the Holo over to Katniss, Homes testifies to Jackson that Boggs truly did pass it onto her.
Further into the mission, when Jackson and Leeg 1 go missing, Homes informs Katniss that they stayed behind at the Meat Grinder to hold the mutts back. When Katniss tries to go back for them, Homes stops her telling her not to waste their lives and that it is already too late for them. Soon after, Homes is also killed and although his death is not described, it can be assumed that he was killed by the lizard mutts along with Finnick and Castor.
