Elyse is a civilian girl with the 2nd Massachusetts Militia Regiment. Once she had her arm wounded by unknown reasons. She and her father, Frank, visited Anne Glass to treat it. She went with Terry Clayton to go to a safehouse, which her father was at first opposed to, but finally accepted it. Elyse left the school with Hal, Lourdes, Ben, Matt, Jimmy and Rick among others during the Mech attack.
