I always got the impression the stuff with Chris was phony. I never bought it. But at this point Chris hates her as he believes she nearly got him killed. And then Mateo and her own family - they despise her for Drew's death. Chris has been learning how to run Ewing Oil as JR would have done and Mateo isn't the kind of man you want angry with you, let alone hating you. I'm guessing about 10. Kids grow up fast on soaps. He is leaning to be protective of his mother. And while his parents haven't filled his head with anything bad about Elena, the Ramos's have. And it would be difficult for him not to listen to them as she is their side of the family. Chris might want to worry - what if Jack wants Ewing Oil? Lucy is the head of the family and it's not going to be easy to find a place for Mitch and keep this crew together.
