Together with her brother, Miquel Domínguez, Eleana fought for the Confederación Nacional del Trabajo during the Spanish Civil War. In 1937, Eleana and her brother lived in Barcelona, an anarchist held city. There they befriended the Eighth Doctor and Anji Kapoor. Shortly after, Eleana found Miquel dead and unofficially identified his body. Eleana continued to be a friend of Anji for a number of months. However, when Eleana found that Anji had been keeping records of everything people, including Eleana, had said, she became angry as this could have incriminated her.
