I gave Matt arsenic so that if you try and transplant his heart it will fail.
Matt is strapped to a bed and locked in an operating room waiting for them to take his heart for El Patron.
El Patron is dying and he needs Matt to give him his heart. But Celia tells them that she gave him poison and that if they take Matts, heart, that it will kill El Patron.
When Celia tells El Patron about the poison his heart starts to fail and he goes into shock. Everyone rushes away and Matt is left with Tam Lin and Mr. Alacran. they tell him that El Patron is dead.
Mr. Alacran tells them they have no use for Matt anymore and that they should kill him. Tam Lin agrees and he tells Matt that they turned Celia into an eejit. When they get far enough away Tam Lin tells Matt that he needs to run away meet Maria at her school.
Matt spends the night outside and then heads off towards the border. He has to do some hard rock climbing but he makes it. he waits till dark and then makes a run for the border, farm patrol grabs his backpack but he shrugs them off and makes it to the other side.
