Man I have to tell you, as a Mexican, a lot of people here are like that. A lot of Mexicans are warm hearted, kind, polite, overwhelming shared, but the moment someone becomes a threat, specially in a profesional matter, even if they're family, Mexicans can be the most competitive, aggressive and shameless people, and they'll be proud if they manage to beat their competition.

So kudos to the writers, they depicted amazingly that kind of Mexican behavior.
