The two travel to the hotel and discover White's secret room where they find co-ordinates pointing to Oberhauser's operations base in the desert. They travel by train to the nearest station, but are once again confronted by Hinx; they engage in a fight throughout the train in which Mr Hinx is eventually thrown off the train by Bond with Swann's assistance. After arriving at the station, Bond and Swann are escorted to Oberhauser's base. There, he reveals that Spectre has been staging terrorist attacks around the world, creating a need for the Nine Eyes programme. In return Spectre will be given unlimited access to intelligence gathered by Nine Eyes. Bond is tortured as Oberhauser discusses their shared history: after the younger Bond was orphaned, Oberhauser's father, Hannes, became his temporary guardian. Believing that Bond supplanted his role as son, Oberhauser killed his father and staged his own death, subsequently adopting the name Ernst Stavro Blofeld and going on to form Spectre. Bond and Swann escape, destroying the base in the process, leaving Blofeld to apparently die during the explosion.
Try to answer this question if possible (otherwise reply "unanswerable"): Swann is tortured as who discusses their shared history?
