Biography
Santiago was born in Santiago, Chile (for which he was named) in a caravan at the foothills of the Andes Mountains. He travelled the world with his parents, protesting for environmental and political causes, but felt estrangement due to the family being separated all over the world for months at a time because of their lifestyle. When the Doctor, whom he had always wanted to meet before it was too late, was declared dead, he was taken to the UNIT base. There, he met aliens, including the Shansheeth and Groske, for the first time. He quickly made friends with Rani and Clyde and witnessed a plot by the Shansheeth and Colonel Tia Karim to steal the Doctor's TARDIS by making a key from the memories of his grandmother and Sarah Jane Smith. Santiago was advised to make some changes regarding the relationship with his parents. Santiago left with his grandmother to travel to Norway by hovercraft. (SJA: Death of the Doctor)
