Rolanda is one of the few people to follow Dara Hubbell's group into Nuka-World. She and her friends are awaiting someone to help them travel to another world. She believes that Hubology saved her life and "expanded her mind."
Rolanda's last name is related to rotational movement (Hooper). This trait is shared by several of the other Hubologists as well (Tula Spinney, Maurice Turner, Phil Roller).
