Gabriel Castillo

Zoe Castillo's father Gabriel is a mild-mannered, Hispanic-complexioned bioneer who appears to be in his forties or fifties. He has a clear Oxonian accent (we know that the Castillos lived in London when Zoe was small) and is a contented 23rd century citizen whose job takes him all over the world. At the beginning of Dreamfall, Gabriel is preparing for a business trip to Bombay, possibly connected to a recent promotion, but he is slightly cagey about the details of his trip.

He is clearly used to just having himself and Zoe at home – Zoe's mother died when she was four and whether they were married or not is unknown. Helena Chang, another bioneer, mentions that she "knew a Castillo once. A long time ago," and says that Zoe looks very much like her father. Zoe's conversations with her imply that Chang is her biological mother, but as she makes no mention of Chang to her father, there is no way to gauge the likelihood of this from his reaction.

Gabriel is very protective of his daughter – it is possible this is somehow related to the circumstances of her birth. During the Collapse, when she ten, he made her stay indoors. If Zoe tells him she intends to have a party while he's away, he asks her if there will be any boys or alcohol, and if she tries to leave the house in her underwear he says "I'm telling you right now, no daughter of mine is going out dressed like that." He calls Zoe on her mobile throughout her journey to check up on her, and liaises with Wonkers and the home server to see if she is all right.
