Celia reveals that Steven is Matt's twin brother, created from Matt's own genetic material.
She explains the following:
* The cloning process: Celia was able to extract Matt's DNA while he was still a child. This was done secretly without his knowledge, as part of a plan to create a new clone of El Patron, the ruthless leader who had created Matt.
* Steven's purpose: The plan was for Steven to eventually grow up and replace El Patron, taking control of the drug empire. This plan was put in motion because El Patron feared he would eventually be poisoned or killed by his enemies.
* Matt's potential threat: Celia explains that Matt himself poses a threat to El Patron's control. If Matt's identity were to be revealed and he were to escape, he could disrupt the entire system.
* Steven's unknowing role: Celia emphasizes that Steven is completely unaware of his origins. He has been raised as a special child, trained for a specific purpose.
Celia's revelation is a pivotal moment in the book. It completely changes Matt's understanding of himself and the world around him. He is now faced with the possibility of having a brother who is both a potential ally and a pawn in a dangerous game.
