Rosita was saved from the Cybermen by Jackson Lake, a man who believed himself to be the Doctor. They heard about people going missing and decided to investigate. She first met the real Tenth Doctor when a Cybershade was caught in a building. Rosita saved Lake and the Doctor from almost dying. She later told the Doctor about everything that was going on. The Doctor explained to her and the "Doctor" what had happened. Rosita went with the Doctor and even punched Miss Hartigan in the face when Rosita found out what she was going to do. Rosita saved the orphan children who lived at the work house, forced to work the mechanics of the CyberKing. After the Doctor went away she went to live with Jackson Lake and his son.
